1. As a filler, for example, it can be used in epoxy adhesives.
2. As an analytical reagent, it can be used as an absorbent for carbon dioxide and sulfur dioxide in gas analysis, a reagent for spectral analysis, a high-purity reagent in epitaxial and diffusion processes in semiconductor manufacturing, and for drying ammonia and dehydrating alcohols in laboratories.
3. As a raw material, it can be used to manufacture calcium carbide, soda ash, bleaching powder, etc., and is also used in leather making, wastewater purification, and the production of calcium hydroxide and various calcium compounds.
4. It can be used as a building material, a metallurgical flux, a cement accelerator, and a flux for phosphors. 5. Used as a vegetable oil decolorizing agent, drug carrier, soil conditioner, and calcium fertilizer;
6. Also used in refractory materials and as a desiccant;
7. Can be used to formulate agricultural machinery adhesives No. 1 and No. 2 and underwater epoxy adhesives, and also as a reactant for pre-reaction with 2402 resin;
8. Used for acidic wastewater treatment and sludge conditioning;
9. Can also be used as a boiler shutdown protection agent, utilizing the hygroscopic capacity of lime to keep the metal surfaces of the boiler's steam-water system dry and prevent corrosion. Suitable for long-term shutdown protection of low-pressure, medium-pressure, and small-capacity drum boilers;
10. Can react with water to prepare calcium hydroxide, reaction equation: CaO + H₂O = Ca(OH)₂, which is a combination reaction.
