Calcium

Calcium is a alkaline earth metal, and is the fifth most abundant element by mass in the Earth's crust. It is essential for living organisms, particularly in cell physiology, where movement of the calcium ion Ca2+ into and out of the cytoplasm functions as a signal for many cellular processes. As a major material used in mineralization of bones and shells, calcium is the most abundant metal by mass in many animals. It is uesd as a reducing agent in the extraction of other metals, such as uranium, zirconium, and thorium, as a deoxidizer, desulfurizer, or decarbonizer for various ferrous and nonferrous alloys, and as an alloying agent used in the production of aluminium, beryllium, copper, lead, and magnesium alloys. It is also used in the making of cements and mortars to be used in construction and in the making of cheese, where calcium ions influence the activity of rennin in bringing about the coagulation of milk.

Calcium Borate

Calcium borate can be prepared by reacting calcium metal with boric acid. A hydrated form occurs naturally as the minerals colemanite, nobleite and priceite. One of its uses is as a binder in some grades of hexagonal boron nitride for hot pressing. Other uses are flame retardant in epoxy molding compounds, a ceramic flux in some ceramic glazes, reactive self-sealing binders in hazardous waste management, additive for insect-resistant polystyrene, fertilizer, and production of boron glasses.

Calcium Boride

Calcium boride is a compound of calcium and boron. It is an important material due to its high electrical conductivity, hardness, chemical stability, and melting point. It is used in the manufacturing of boron-alloyed steel and as a deoxidation agent in production of oxygen-free copper. It can also serve as a high temperature material, surface protection, abrasives, tools, and wear resistant material. It is highly conductive, has low work function, and thus can be used as a cathode material. It is also a promising candidate for n-type thermoelectric materials, because its power factor is larger than or comparable to that of common thermoelectric materials Bi2Te3 and PbTe.

Calcium Carbide

Calcium Carbide is a chemical compound containing calcium and carbide.Pure form of calcium carbide is colorless, but most of the material is produced industrially.It is made in a kind of furnace called an electric arc furnace, which can reach temperatures much hotter than those that are obtained through simple combustion. The basic chemical method used to make the material has not changed since it was discovered in 1888.Calcium carbide reacts with nitrogen at high temperature to form calcium cyanamide.Calcium carbide is used in carbide lamps, used in the desulfurisation of iron, as a fuel in steelmaking to extend the scrap ratio to liquid iron,as a powerful deoxidizer at ladle treatment facilities.Calcium carbide is used in toy cannons such as the Big-Bang Cannon, as well as in bamboo cannons.

Calcium Carbonate

Calcium carbonate is a chemical compound. It is a common substance found in rock in all parts of the world, and is the main component of shells of marine organisms, snails, pearls, and eggshells. It is the active ingredient in agricultural lime, and is usually the principal cause of hard water. Calcium carbonate is commonly used medicinally as a calcium supplement or as an antacid, but excessive consumption can be hazardous. The main use of calcium carbonate is in the construction industry. It is used in the oil industry in drilling fluids as a formation bridging and filtercake sealing agent and may also be used as a weighting material to increase the density of drilling fluids to control downhole pressures. It is widely used as an extender in paints and as a filler in plastics. It is also used in adhesives, sealants, and decorating fillers. Calcium carbonate is a common ingredient for many glazes/ceramics in its white powdered form.

Properties Suppliers
Calcium Chloride Hexahydrate

Calcium chloride hexahydrate is used as a brine for refrigeration plants, ice and dust control on roads, and in concrete.

Properties Suppliers
Calcium Chromate

Calcium chromate normally occurs as the dihydrate. It is used as a pigment, a corrosion inhibitor, and in electroplating, photochemical processing, and industrial waste treatment.

Properties Suppliers
Calcium Cyanamide

Calcium cyanamide is a calcium compound used as fertilizer, first synthesized in 1898 by Adolph Frank and Nikodem Caro. It is formed when calcium carbide reacts with nitrogen. It was used to produce sodium cyanide by fusing with sodium carbonate, which was used in cyanide process in gold mining. It can also be used in the preparation of calcium cyanide and melamine. Thiourea can be produced by the reaction of hydrogen sulfide with calcium cyanamide in the presence of carbon dioxide.

Properties Suppliers
Calcium Formate

Calcium formate, is the calcium salt of formic acid. It is used as a food additive. The mineral form is very rare and called formicaite. It is known from a few boron deposits. It may be produced synthetically by reacting calcium oxide or calcium hydroxide with formic acid.

Properties Suppliers
Calcium Hydride

Calcium hydride reacts vigorously with water liberating hydrogen gas. It is thus used as a drying agent. It is widely used as a desiccant for basic solvents such as amines and pyridine. It is also used to pre-dry solvents prior to the use of a more reactive desiccant.
