일반 설명

Calcium oxide (CaO), also known asquicklime, is an ionic compound widely recognized for its high reactivity andversatility. This product features a particle size of <160 nm, a density of3.3 g/mL at 25 °C, and an assay of 98% trace metals basis. Calcium oxideappears as a white solid and is highly hygroscopic, readily reacting withmoisture in the air. Calcium oxide is extensively utilized in variousindustrial applications, including the production of cement and glass, where itacts as a flux. It is also employed in the steel industry as a slag conditionerand in the manufacturing of calcium hydroxide through hydration. Additionally,CaO is used in water treatment processes to adjust pH levels and in theproduction of calcium-based chemicals. CaO is also used in:Synthesis of Nanoparticles:Calcium oxide serves as a precursor in the synthesis of calcium-basednanomaterials, which have applications in catalysis and drug delivery. Glass Manufacturing: Fluxing Agent: CaO is used as a flux inglassmaking to lower the melting point of silica, improving the melting processand enhancing the properties of the glass.
