Physical Properties:
Appearance: White powder or fine crystals.
Density: Approximately 2.24 g/cm³ (at 25℃).
Solubility: Solubility in water decreases with increasing temperature, but it remains a strong alkali.
Hygroscopicity: Easily absorbs carbon dioxide and water vapor from the air, gradually turning into calcium carbonate and water.
Chemical Properties:
Strong Alkalinity: Reacts with acids to form salts and water.
Thermal Stability: Loses moisture to form calcium oxide when heated to 580℃.
Reactivity: Reacts with various non-metallic oxides to form corresponding salts, such as reacting with carbon dioxide to form calcium carbonate.
