Kainite
Kainite ( or ) (KMg(SO4)Cl·3H2O) is an evaporite mineral in the class of "Sulfates (selenates, etc.) with additional anions, with H2O" according to the Nickel–Strunz classification. It is a hydrated potassium-magnesium sulfate-chloride, naturally occurring in irregular granular masses or as crystalline coatings in cavities or fissures. This mineral is dull and soft, and is colored white, yellowish, grey, reddish, or blue to violet. Its name is derived from Greek καινος ainos("(hitherto) unknown"), as it was the first mineral discovered that contained both sulfate and chloride as anions. Kainite forms monoclinic crystals. Properties Kainite is of bitter taste and soluble in water. On recrystallization picromerite is deposited from the solution. Genesis and occurrence Kainite was discovered in the Stassfurt salt mines in today's Saxony-Anhalt, Germany in 1865 by the mine official Schöne and was first described by Carl Friedrich Jacob Zincken. Kainite is a typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaliophilite
Kalsilite ( K Al Si O4) is a vitreous white to grey feldspathoidal mineral that is found in some potassium-rich lavas, such as from Chamengo Crater in Uganda. It has a relative hardness In materials science, hardness (antonym: softness) is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. In general, different materials differ in their hardness; for example hard ... of 5.5.

Alum-(K)
Alum-(K) is a hydrous potassium aluminium sulfate mineral with formula KAl(SO4)2·12(H2O). It is the mineral form of potassium alum and is referred to as potassium alum in older sources. It is a member of the alum group. It occurs as colorless to white, soft isometric crystals and efflorescence coatings. Rare crystals are octahedral in form if occurring as precipitates from neutral water solution, but cubic in form if the solution is alkaline. It occurs as a precipitate around volcanic fumaroles and solfataras. It also occurs as an alteration in argillaceous sediments or coal beds which contain oxidizing sulfide minerals (pyrite or marcasite). Occurs associated with alunogen, pickeringite, epsomite, melanterite, gypsum and native sulfur. Occurrences include Mount Vesuvius, Italy and Alum Cave, Sevier County, Tennessee Sevier County ( ) is a county of the U.S. state of Tennessee. As of the 2020 census, the population was 98,380.

Kalinite
Kalinite is a mineral composed of hydrated potassium aluminium sulfate (a type of alum). It is a fibrous monoclinic alum, distinct from isometric potassium alum,American Mineralogist (1923) 8:15 named in 1868. Its name comes from ''kalium'' (derived from Arabic: القَلْيَه al-qalyah “plant ashes”) which is the Latin name for potassium, hence its chemical symbol, "K". A proposal to remove recognition of kalinite as a mineral species was submitted to the International Mineralogical Association, however, kalinite is still on the list of approved minerals. Many older samples, however, have been found to be potassium alum. Environment Kalinite is a rare secondary mineral observed in the oxidized zone of mineral deposits, as efflorescence on alum slates, in caves, and as a volcanic sublimate.American Mineralogist (1927) 12:14 It is associated with jarosite, KFe3+3(SO4)2(OH)6, and cuprian melanterite (pisanite), (Fe2+,Cu2+)SO4·7H2O, at Quetena, Chile Chile, ...

Kalicinite
Potassium bicarbonate (IUPAC name: potassium hydrogencarbonate, also known as potassium acid carbonate) is the inorganic compound with the chemical formula KHCO3. It is a white solid. Production and reactivity It is manufactured by treating an aqueous solution of potassium carbonate with carbon dioxide: :K2CO3 + CO2 + H2O → 2 KHCO3 Decomposition of the bicarbonate occurs between : :2 KHCO3 → K2CO3 + CO2 + H2O This reaction is employed to prepare high purity potassium carbonate. Uses Food and drink This compound is a source of carbon dioxide for leavening in baking. It can substitute for baking soda (sodium bicarbonate) for those with a low-sodium diet, and it is an ingredient in low-sodium baking powders. As an inexpensive, nontoxic base, it is widely used in diverse application to regulate pH or as a reagent. Examples include as buffering agent in medications, an additive in winemaking. Potassium bicarbonate is often found added to club soda to improve taste, and to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalgoorlieite
Kalgoorlieite (IMA2015-119) is a mineral from Kalgoorlie, Western Australia. Kalgoorlieite is the fourth oxygen-free arsenic-tellurium Tellurium is a chemical element with the symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionall ... mineral after benleonardite, debattistiite, and törnroosite. It was discovered in 2015 by a Curtin University academic Dr Kirsten Rempel while she was checking samples in the Kalgoorlie School of Mines Museum, and declared a new mineral in 2016, after verification and classification.
