[0002] Calcium hydroxide is a white powdery solid with the chemical formula Ca(OH)2, commonly known as slaked lime and quicklime. Its aqueous solution is called clear limewater. Calcium hydroxide has the general properties of an alkali and is a strong alkali. Calcium hydroxide is a binary strong alkali, but is only slightly soluble in water. Calcium hydroxide is widely used in industry. In order to ensure the storage of calcium hydroxide and reduce the rapid reaction of carbon dioxide in the air with calcium hydroxide when air enters it, the calcium hydroxide needs to be dried to reduce its reaction rate with calcium hydroxide during work and increase the shelf life of calcium hydroxide.
