calcium | Definition, Properties, & Compounds | Britannica
Calcium constitutes 3.64 percent of Earth’s crust and 8 percent of the Moon’s crust, and its cosmic abundance is estimated at 4.9 × 10 4 atoms (on a scale where the abundance of silicon is 10 6 atoms). As calcite (calcium carbonate), it occurs on Earth in limestone, chalk, marble, dolomite, eggshells, pearls, coral, stalactites, stalagmites, and the shells of many marine animals.

Calcium chloride for ice removal, ice melt, snow removal, …
Calcium chloride is a naturally occurring compound produced and found worldwide and commercially sold for ice melting, snow melting, and dust control appliions. Typically, when calcium chloride is found in nature, it is in a liquid form and always coupled with other mineral salts, such as potassium chloride (potash), sodium chloride (salt brine), and magnesium chloride.
Bentonite - an overview | ScienceDirect Topics
Early uses of bentonite in the 1800s, included lubricant for wagon wheels, sealant for log cabin roofs, and soap. Modern uses are highly variable. In foundry or metal casting, bentonite is mixed with sand to make the molds. The bentonite forms a pliable bond with
Properties | Bentonite
Bentonite vitrifiion temperature is higher than other clays. Therefore, when used as an additive, it makes green sand more durable, and, in particular, more resistant to heat stress. Surface properties (coagulation– absorption – adsorption) Bentonite absorption – adsorption properties are determined by the high specific surface and free charges present on each micelle.
