CaCl2
ceramicCalcium chloride (CaCl₂) is an inorganic ionic ceramic compound with significant hygroscopic and deliquescent properties, making it fundamentally different from typical load-bearing ceramics like alumina or silicates. It is primarily used in industrial applications where its moisture-absorbing and thermal properties are advantageous rather than structural strength—including de-icing operations, dust control, food preservation, and as a drying agent in laboratories and manufacturing. Engineers select CaCl₂ when hygroscopic behavior is the design requirement, though its solubility in water and relatively low mechanical strength limit its use to non-structural roles where chemical function outweighs load-bearing capability.
