Application

Calcium chloride hexahydrate serves as an effective phase change material (PCM) primarily used in the storage of solar energy and in various building applications. This colorless to off-white crystalline solid is known for its deliquescent properties, meaning it readily absorbs water from its surroundings. Upon heating to 100°C, these crystals release water, making them particularly suitable for managing thermal energy in various systems.
