Calcium Chloride Lumps, Grade Standard : Technical Grade for Industrial

Calcium chloride is a chemical compound with the formula CaCl₂. It is commonly found in solid form as white, hard lumps or pellets. These lumps are highly hygroscopic, meaning they readily absorb moisture from the air, making calcium chloride an effective desiccant and de-icing agent. Key Characteristics: Appearance: White to off-white, hard, crystalline lumps Odor: Odorless Solubility: Highly soluble in water, releasing heat (exothermic reaction); also soluble in alcohols like ethanol Hygroscopic Nature: Absorbs moisture from the environment, which can lead to the lumps becoming damp or dissolving into a liquid solution over time Chemical Formula: CaCl₂ Production: Source: Typically produced by the reaction of limestone (calcium carbonate) with hydrochloric acid, followed by evaporation and crystallization processes Processing: Can also be obtained as a byproduct from the Solvay process in the production of sodium carbonate (soda ash) Common Uses: De-icing Agent: Widely used to melt ice and snow on roads, sidewalks, and other surfaces due to its ability to lower the freezing point of water Dust Control: Used on unpaved roads and construction sites to control dust by absorbing moisture and binding dust particles Desiccant: Employed in moisture control applications to keep environments dry, such as in packaging, storage, and drying tubes in laboratories Concrete Accelerator: Added to concrete mixtures to speed up the curing process, especially in cold weather conditions Food Additive: Occasionally used as a firming agent in canned vegetables, or to maintain the texture of cheese in the food industry
