Calcium Hydroxide Powder

Calcium Hydroxide Powder, commonly termed slaked lime, is an inorganic compound consisting of calcium and hydroxide ions with the formula Ca(OH)2. It appears as a white, fine powder with a slightly soluble nature, dissolving approximately 1.73 grams per liter at 20°C. This powder is commonly supplied in industrial-grade form with a typical purity aligning with standard specifications, suitable for various chemical and industrial applications. Handling requires attention to its high alkalinity and moderate caustic characteristics; it should be kept away from acidic substances to prevent hazardous reactions. This compound is typically used at dosage levels dependent on application, for example, water treatment often involves addition rates around 50 to 100 mg/L for pH adjustment. Buyers should note that its handling temperature should be controlled below decomposition thresholds, and it must be stored in moisture-free environments due to its reactivity with water. The powder form facilitates precise dosing and uniform mixing in processes where alkaline conditions are needed.

In industrial water treatment, Calcium Hydroxide Powder serves as an effective agent for raising pH and precipitating impurities such as heavy metals and phosphates, enabling the provision of cleaner water for manufacturing and municipal use. Without proper alkalinity control, water systems can suffer from corrosion, dirty processes, or environmental discharge failure. In construction applications, the powder enhances soil stability by chemically reacting with clay particles to increase load-bearing capacity and reduce plasticity, ensuring structural foundations and roadbeds meet durability requirements. This directly influences the longevity and safety of infrastructure projects.
