Sodium Silicate
Sodium silicate is a generic name for chemical compounds with the formula or ·, such as sodium metasilicate , sodium orthosilicate , and sodium pyrosilicate . The anions are often polymeric. These compounds are generally colorless transparent solids or white powders, and soluble in water in various amounts. Sodium silicate is also the technical and common name for a mixture of such compounds, chiefly the metasilicate, also called waterglass, water glass, or liquid glass. The product has a wide variety of uses, including the formulation of cements, passive fire protection, textile and lumber processing, manufacture of refractory ceramics, as adhesives, and in the production of silica gel. The commercial product, available in water solution or in solid form, is often greenish or blue owing to the presence of iron-containing impurities. In industry, the various grades of sodium silicate are characterized by their SiO2:Na2O weight ratio (which can be converted to molar ratio ...

Basil Valentine
Basil Valentine is the Anglicised version of the name Basilius Valentinus, ostensibly a 15th-century alchemy, alchemist, possibly Canon (priest), Canon of the Benedictine Priory of Saint Peter in Erfurt, Erfurt, Germany but more likely a pseudonym used by one or several 16th-century German authors. According to John Maxson Stillman, who wrote on the history of chemistry, there is no evidence of such a name on the rolls in Germany or Rome and no mention of this name before 1600. His putative history, like his imaginary portrait, appears to be of later creation than the writings themselves. During the 18th century it was suggested that the author of the works attributed to Basil Valentine was Johann Thölde, a salt manufacturer in Germany who lived roughly 1565-1624. Modern scholarship now suggests that one author was Thölde, but that others were involved. Thölde published the first five books under Valentine's name. Whoever he was, Basil Valentine had considerable chemical kn ...

Silicic Acid
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula , most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as a synthetic product. Notable examples include fused quartz, fumed silica, silica gel, opal and aerogels. It is used in structural materials, microelectronics (as an electrical insulator), and as components in the food and pharmaceutical industries. Structure In the majority of silicates, the silicon atom shows tetrahedral coordination, with four oxygen atoms surrounding a central Si atomsee 3-D Unit Cell. Thus, SiO2 forms 3-dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms. In contrast, CO2 is a linear molecule. The starkly different structures of the dioxide ...

Johann Nepomuk Von Fuchs
Johann Nepomuk von Fuchs (15 May 1774 – 5 March 1856) was a German chemist and mineralogist, and royal Bavarian privy councillor. Biography He was born at Mattenzell, near Falkenstein in the Bavarian Forest. In 1807 he became professor of chemistry and mineralogy at the Ludwig Maximilian University, which was located in Landshut at the time, and in 1823 conservator of the mineralogical collections at Munich, where he was appointed professor of mineralogy three years later, when the university was relocated. He retired in 1852, was ennobled by the king of Bavaria in 1854, and died at Munich on 5 March 1856. He is largely known for his mineralogical observations and for his work on waterglass (sodium silicate). He used it to develop stereochromy, a kind of fresco painting where the pigments are fixed with waterglass. Historically, the substance was sometimes referred to as "Fuchs's soluble glass". Also, he developed a scientific method for the production of cement and made c ...

Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change. Contribution of Working Group III to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change Cambridge University Press, Cambridge, United Kingdom and New York, NY, USA Carbon dioxide is soluble in water and is found in groundwater, lakes, ice caps, ...

Calcination
Calcination refers to thermal treatment of a solid chemical compound (e.g. mixed carbonate ores) whereby the compound is raised to high temperature without melting under restricted supply of ambient oxygen (i.e. gaseous O2 fraction of air), generally for the purpose of removing impurities or volatile substances and/or to incur thermal decomposition. The root of the word calcination refers to its most prominent use, which is to remove carbon from limestone (calcium carbonate) through combustion to yield calcium oxide (quicklime). This calcination reaction is CaCO3(s) → CaO(s) + CO2(g). Calcium oxide is a crucial ingredient in modern cement, and is also used as a chemical flux in smelting. Industrial calcination generally emits carbon dioxide (), making it a major contributor to climate change. A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature processing (550–1150 °C, or 1000–2100 °F) within a controlled ...

Potassium Carbonate
Potassium carbonate is the inorganic compound with the formula K2 CO3. It is a white salt, which is soluble in water. It is deliquescent, often appearing as a damp or wet solid. Potassium carbonate is mainly used in the production of soap and glass. History Potassium carbonate is the primary component of potash and the more refined pearl ash or salts of tartar. Historically, pearl ash was created by baking potash in a kiln to remove impurities. The fine, white powder remaining was the pearl ash. The first patent issued by the US Patent Office was awarded to Samuel Hopkins in 1790 for an improved method of making potash and pearl ash. In late 18th-century North America, before the development of baking powder, pearl ash was used as a leavening agent for quick breads. Production Potassium carbonate is prepared commercially by the reaction potassium hydroxide with carbon dioxide: : 2 KOH + CO2 → K2CO3 + H2O From the solution crystallizes the sesquihydrate K2CO3·H2O ("potash ...

Potassium Silicate
Potassium silicate is the name for a family of inorganic compounds. The most common potassium silicate has the formula K2SiO3, samples of which contain varying amounts of water. These are white solids or colorless solutions.Gerard Lagaly, Werner Tufar, A. Minihan, A. Lovell "Silicates" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, 2005. Synthesis, structure, reactions Potassium silicate can be synthesized in the laboratory by treating silica with potassium hydroxide, according to this idealized equation: :\mathit + 2KOH -> K2O.\mathit + H2O These solutions are highly alkaline. Addition of acids causes the reformation of silica. K2SiO3 adopts a chain or cyclic structures with interlinked SiO32− monomers. Each Si is tetrahedral. Uses Woodwork protection against fire Impregnation of wood with a potassium silicate solution is an easy and low cost way for rendering the woodwork of houses secure against catching fire. The woodwork is first saturated with a dilut ...

Johann Rudolf Glauber
Johann Rudolf Glauber (10 March 1604 – 16 March 1670) was a German-Dutch alchemy, alchemist and chemist. Some historians of science have described him as one of the first chemical engineers. His discovery of sodium sulfate in 1625 led to the compound being named after him: "Glauber's salt". Life Born in 1604 in Karlstadt am Main, the son of a barber, he was one of a large family and did not finish school, but is thought to have studied pharmacy and visited laboratories.This section incorporates material from the German Wikipedia and the Galileo Project which are referenced to German sources He said that he was glad that he had not suffered the grind of high school but had instead learned by experience. He lived in Vienna (1625), Salzburg, Giessen, Wertheim am Main, Wertheim (1649–1651), Kitzingen (1651–1655), Basel, Paris, Frankfurt am Main, Cologne and Amsterdam (1640–1644, 1646–1649, 1656-death). He worked first manufacturing mirrors and later for two periods as ...
