Product introduction: 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. 1,product name:calcium metal 2,Shape :powder, lump and granulates 3,CAS:7440-70-2 4,Density:1.54g/cm 5,Melting point:850C 6,Boiling point:1440 C(lit.) 7,Application:Wheel keel 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.
