Calcium Chloride is an inorganic compound composed of calcium and chlorine ions, with the formula CaCl₂. It commonly appears as white crystalline flakes or granules that are highly soluble in water. Its hygroscopic nature means it readily absorbs moisture from the air, which is why it’s often used as a drying agent or desiccant.
Functionally, Calcium Chloride works by releasing calcium and chloride ions in solution. These ions affect various chemical and physical processes depending on the application. For dust control, it attracts water from the atmosphere into the surface layer of unpaved roads, maintaining moisture levels that reduce dust emissions effectively. In de-icing, it lowers the freezing point of water, causing ice and snow to melt at lower temperatures than pure water would allow.
The compound also accelerates cement hydration in concrete, shortening cure times and improving early strength gain. In water treatment, it serves as a source of calcium ions to correct water hardness or aid coagulation. Food processing applications benefit from its stability and ionic strength, as it regulates firmness or acts as a preservative in certain conditions.
Key properties critical to performance include high solubility (approx. 74.5 g/100 mL at 20°C), a neutral to slightly alkaline pH in solution, and a density around 2.15 g/cm³ in solid form. Purity varies with application but typically exceeds 90% for industrial grades. Bulk supply from reputable regional suppliers like Zenco Systems Ltd ensures product consistency, with packaging designed to prevent moisture ingress and maintain chemical integrity in transit and storage throughout East Africa.
