Cobalt(II,III) oxideCobalt(II,III) oxide is an inorganic compound with the formula Co3O4. Along with cobalt(II) oxide, it is one of two well characterized and stable cobalt oxides. It is a black antiferromagnetic solid. As a mixed valence compound, its formula is sometimes written as Co2+Co3+2O4 and sometimes as CoO·Co2O3. It occurs naturally as the rare mineral guite which is named in honor of Prof. Xiangping Gu (1964-).
Cobalt(II) nitrateCobalt nitrate is the inorganic compound with the formula Co(NO3)2.xH2O. It is a cobalt(II) salt. The most common form is the hexahydrate Co(NO3)2·6H2O, which is a red-brown deliquescent salt that is soluble in water and other polar solvents.
Ceramic glazeCeramic glaze, or simply glaze, is a glassy coating on ceramics. It is used for decoration, to ensure the item is impermeable to liquids and to minimize the adherence of pollutants. Glazing renders earthenware impermeable to water, sealing the inherent porosity of earthenware. It also gives a tougher surface. Glaze is also used on stoneware and porcelain.
Inorganic compoundAn inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds—that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as inorganic chemistry. Inorganic compounds comprise most of the Earth's crust, although the compositions of the deep mantle remain active areas of investigation. All allotropes of carbon and some simple carbon compounds are often considered inorganic.
Chemical formulaA chemical formula is any of several kinds of notation for expressing the composition and structure of a chemical compound. Chemical formulas use element symbols for the atoms of each chemical element in a compound. There are several conventional types of chemical formula that present different levels of detail.
CeramicA ceramic is any of the various hard, brittle, heat-resistant, and corrosion-resistantmaterials made by shaping and then firing an inorganic, nonmetallic material, such as clay, at a high temperature. Common examples are earthenware, porcelain, and brick. The earliest ceramics made by humans were fired clay bricks used for building house walls and other structures.
Vitreous enamelVitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating. The word vitreous comes from the Latin , meaning "glassy". Enamel can be used on metal, glass, ceramics, stone, or any material that will withstand the fusing temperature.
PericlasePericlase is a magnesium mineral that occurs naturally in contactmetamorphic rocks and is a major component of most basic refractory bricks. It is a cubic form of magnesium oxide (MgO). In nature it usually forms a solid solution with wüstite (FeO) and is then referred to as ferropericlase or magnesiowüstite. It was first described in 1840 and named from the Greek περικλάω (to break around) in allusion to its cleavage.SOLIDIn object-oriented programming and functional programming, SOLID is a mnemonicacronym for five principles intended to make source code more understandable, flexible, and maintainable. Although the principles apply to object-oriented programming, they also form a core philosophy for methodologies such as agile software development and adaptive software development.
AntiferromagnetismAntiferromagnetism is a type of magnetic ordering, along with ferromagnetism and ferrimagnetism. In antiferromagnets the individual magnetic dipoles are oriented in a way such that the bulk of the material has a vanishing total magnetization. In the simplest model, as shown in the picture on the right, neighboring moments in an ordered lattice are oriented antiparallel to one another.
KilnA kiln is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Kilns have been used for millennia to turn objects made from clay into pottery, tiles and bricks. Various industries use rotary kilns for pyroprocessing (to calcinate ores, such as limestone to lime for cement) and to transform many other materials.
Olive (color)Olive, also called olive green, is a dark shade of yellowish green, like that of unripe or green olives. As a color word in the English language, it appears in late Middle English.
GreyGrey or gray is an intermediate color between black and white. It is a neutral or achromatic color, meaning that it has no chroma. It is the color of a rain or storm cloud, of ash, and of lead. The first recorded use of grey as a color name in the English language was in 700 CE. Grey is the dominant spelling in European and Commonwealth English, while gray is more common in American English; however, both spellings are valid in both varieties of English.*As an Amazon Associate I earn from qualifying purchases.
