Appearance & Physical Properties
Calcium oxide presents white or off-white solid in normal storage conditions, available in powder, granular and flake forms. Minor gray or light yellow tint may appear due to trace industrial impurities. The product is highly hygroscopic, easily absorbing moisture and carbon dioxide from ambient air. It reacts violently with water and generates massive heat. As a typical inorganic oxide, it is soluble in acid and almost insoluble in ethanol. Stable physical form ensures convenient international transportation and long-term storage with sealed packaging.
Main Applications
Calcium oxide serves as a core industrial raw material for multiple global industries. In construction industry, it acts as essential material for mortar and concrete preparation. In chemical industry, it is used for pH adjustment, neutralization reaction and raw material processing. In environmental protection, it applies to wastewater treatment, flue gas desulfurization and soil remediation. Additionally, it is widely used in metallurgy, paper making, leather processing and agricultural soil improvement. The versatile performance makes it a high-demand chemical product for global import and export trade.
