Calcium is a silvery white metal that is harder and heavier than lithium, sodium, and potassium;
It melts at 815 C. The chemical nature of metallic calcium is very active. In the air, calcium is quickly oxidized and masked with an oxide film. When heated, calcium will burn and emit a beautiful glow of brick red. Calcium and cold water have a slower effect, and intense chemical reactions occur in hot water to release hydrogen (lithium, sodium, and potassium can cause intense chemical reactions even in cold water). Calcium is also easily combined with halogens,
sulfur, nitrogen, and the like.

Product use:
At present, in the steel industry, the main use of metal calcium is to process into metal calcium particles, and then to make calcium iron wire or pure calcium wire, and finally used for steel refining outside the furnace, its role is to desulfurization, deoxidation, increase the fluidity of molten steel. Promote the rapid rise of inclusions in molten steel, generally used in the production of high-quality steel; as a dehydrating agent to produce anhydrous alcohol; in the petroleum industry, as a desulfurizing agent, in the metallurgical industry, it is used to deoxidize or
desulfurize . However, calcium compounds have a very wide range of uses, especially in the construction industry.
Hydrous Kaolin is characterized by its fine particle size, high brightness and rheology. We develop fine and ultra fine grades of Hydrous Kaolin from our best reserves, for various industries including Paint, Paper, Printing Inks, Paper board, Rubber, etc.
Kaolin or china clay is a natural mineral found in partly decompo-sed granite, an igneous feldsparic rock. Chemically, kaolin is a hydrated aluminium silicate containing Al2O3.2SiO2.2H2O. Kaolin was first discovered in the mountainous province of Kiangsi, China in A.D. 500. The word â??kaolinâ?? derives from the Chinese character â??kaolinâ?? which means high ridge. It was first used by the Chinese to make high quality porcelain. At PURESIL INDIA, processed or refined kaolin is available in white powder form, granule cum powder form, and in lumps form. The various grades and their applications are:

Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. Bentonite is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite. The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al). For industrial purposes, two main classes of bentonite exist: sodium and calcium bentonite.
The chemical formula of Bentonite is Al2H2Na2O13Si4 (Sodium) and Al2H2O12Si4 (Calcium)
