Calcium is a reactive, soft metal that is a member of the alkaline earth elements. It is found in the minerals dolomite, gypsum, plagioclases, amphiboles, pyroxenes and garnets.
Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys.
Calcium compounds are widely used. There are vast deposits of limestone (calcium carbonate) used directly as a building stone and indirectly for cement. When limestone is heated in kilns it gives off carbon dioxide gas leaving behind quicklime (calcium oxide). This reacts vigorously with water to give slaked lime (calcium hydroxide). Slaked lime is used to make cement, as a soil conditioner and in water treatment to reduce acidity, and in the chemicals industry. It is also used in steel making to remove impurities from the molten iron ore. When mixed with sand, slaked lime takes up carbon dioxide from the air and hardens as lime plaster.
Gypsum (calcium sulfate) is used by builders as a plaster and by nurses for setting bones, as ‘plaster of Paris’.
Stanford Advanced Materials (SAM) now can provide various Calcium products including:

Calcium (Ca) Evaporation Materials
Micro calcium hexaboride has diverse uses in traditional & high-tech industries like mechanics, electronics, aeronautics, metallurgy, chemistry, environment, etc.
Our high-quality calcium nitride powder features in high purity and uniform particle size distribution. Different granularity can be provided according to customers needs.
Calcium fluoride has many uses in the fiber glass, ceramic, welding rod and glass industry, as well as in blending with burned lime & dolomite for the steel industry.
Calcium Fluoride is often used in spectroscopic windows and lenses due to its high transmission from 250nm to 7µm. Its low absorption and high damage threshold make it a popular choice for excimer laser optics.
