The pure material is colorless, while pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC 2 (the rest is CaO (calcium oxide), Ca 3 P 2 (calcium phosphide), CaS (calcium sulfide), Ca 3 N 2 (calcium nitride), SiC (silicon carbide), C , etc.). In the presence of trace moisture, technical-grade calcium ...
Calcium peroxide or calcium dioxide is the inorganic compound with the formula CaO 2. It is the peroxide (O 2 2− ) salt of Ca 2+ . Commercial samples can be yellowish, but the pure compound is white.
A CAS Registry Number has no inherent meaning, but is assigned in sequential, increasing order when the substance is identified by CAS scientists for inclusion in the CAS Registry database. A CAS RN is separated by hyphens into three parts, the first consisting from two up to seven digits, [ 9 ] the second consisting of two digits, and the ...
Lime is an inorganic material composed primarily of calcium oxides and hydroxides. It is also the name for calcium oxide which is used as an industrial mineral and is made by heating calcium carbonate in a kiln. Calcium oxide can occur as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. [1]
Bioglass 45S5 or calcium sodium phosphosilicate, is a bioactive glass specifically composed of 45 wt% SiO 2, 24.5 wt% CaO, 24.5 wt% Na 2 O, and 6.0 wt% P 2 O 5. [1] Typical applications of Bioglass 45S5 include: bone grafting biomaterials , repair of periodontal defects, cranial and maxillofacial repair, wound care, blood loss control ...
Calcium silicates are produced by treating calcium oxide and silica in various ratios. Their formation is relevant to Portland cement. [5] Calcium silicate is a byproduct of the Pidgeon process, a major route to magnesium metal. The process converts a mixture of magnesium and calcium oxides as represented by the following simplified equation: [6]
