Calcium carbonate (customary name – calcite) consists of a carbonic acid calcium salt.. What are the features of calcium carbonate? This inorganic compound has … WebThe reason is that sodium carbonate reacts with calcium chloride to form CaCO 3. The ability of calcium carbonate to improve wear resistance has also been verified in plastics, rubber, and other materials (Chen et al. 2005; Wen et al. 2024; Mohsenzadeh et al. 2024). An important reason is the high wear resistance of CaCO 3 itself (Zeng 2010).
