Calcium | Article about calcium by The Free Dictionary
Today, calcium metal is usually prepared by electrolysis of fused calcium chloride to which a little calcium fluoride has been added. It is used in alloys with other metals, such as aluminum, lead, or copper; in preparation of other metals, such as thorium and uranium, by reduction; and (like barium) in the manufacture of vacuum tubes to remove residual gases.
Design of an inorganic dual-paste apatite cement using …
The use of hydraulic calcium phosphate cements (CPCs) as bone substitute is impaired by their relatively poor handling due to the need to mix a powder and a liquid during surgery. The aim of the present study was to assess the possibility to design CPCs as inorganic dual-paste cements, where both pastes would be stable for years, but would react as soon as they are mixed together.

METHOD OF PREPARING FIBROUS MAGNESIUM OXIDE - …
16/1/1973· When magnesium chloride is used in the reaction mixture with calcium, barium or strontium chloride auxiliary salt, normally from 2 to 40 mole percent of the magnesium chloride is employed. This 40 percent limitation can be increased as and if sodium, lithium, or potassium halide auxiliary salts are added to said calcium, barium, or strontium salts in increasing amounts.

Fluorine - Production and use | Britannica
Production and use Fluorspar is the most important source of fluorine. In the manufacture of hydrogen fluoride (HF), powdered fluorspar is distilled with concentrated sulfuric acid in a lead or cast-iron apparatus. During the distillation calcium sulfate (CaSO 4) is formed, which is insoluble in HF.) is formed, which is insoluble in HF.
The Use of Barium in Clay Bodies
Fused solubles on the surface can also stick ware together or to kiln shelves and they can seal the surface causing premature bloating during firing. Clay body and material supply companies commonly add barium carbonate to clay bodies in small percentages (0.1-0.8%) to solve this problem (heavy clay industries use more barium, others strive to reduce it to a minimum, often for production reasons).
