CaO, Lime, CAS 1305-78-8, EINECS 215-138-9
Product Name: Calcium Oxide.
Chemical formula: CaO.
Molecular weight: 56.077.
CAS number: 1305-78-8.
EINECS number: 215-138-9.
Purity: 99.9%.
Appearance: White powder.
Characteristic: Absorbs water and carbon dioxide in the air. Calcium oxide reacts with water to form calcium hydroxide and releases heat. Soluble in acidic water, insoluble in alcohol.
Application:
1.Used for fillers, analytical reagents, carbon dioxide absorbers, spectral analysis reagents, epitaxial diffusion processes in semiconductor production, drying of ammonia gas, dehydration of alcohols, etc.
2.Calcium oxide is a raw material for manufacturing calcium carbide, soda ash, bleaching powder, calcium hydroxide, and various calcium compounds.
3.Used for leather making, wastewater purification, sludge conditioning, building materials, metallurgical fluxes, cement accelerators, fluorescent powder fluxes, vegetable oil decolorizers, drug carriers, soil amendments, calcium fertilizers, refractory materials, desiccants, desulfurization, coatings, etc.
4.Used for preparing agricultural machinery No. 1 and No. 2 adhesives and underwater epoxy adhesives, as a reactant for pre reaction with 2402 resin.
5.Used as a shutdown protection agent for boilers, utilizing the moisture absorption ability of lime to keep the metal surface of the boiler water vapor system dry and prevent corrosion. It is suitable for long-term shutdown protection of low-pressure, medium pressure, and small capacity steam drum boilers.
6.Used for calcium carbide, liquid alkali, bleaching solution, bleaching powder, tanning leather, metallurgy, wastewater purification, steel, pesticides, pharmaceuticals, non-ferrous metals, fertilizers, leather making, etc.
