High-Purity Calcium Hydroxide

Calcium Hydroxide, commonly referred to as Hydrated Lime, is an inorganic compound with the chemical formula Ca(OH)2. It appears as a white powder or fine granules that are slightly soluble in water, producing a strongly alkaline solution with a typical pH range between 12.4 and 12.6. Finstar supplies a high-purity grade suitable for various industrial needs, typically having low moisture content that supports stable handling and consistent reactivity. This chemical is mainly used as a reagent or an additive in processes requiring pH adjustment, neutralization, or chemical intermediate functions. Buyers should note that Calcium Hydroxide is incompatible with acids and moisture-sensitive materials; safe handling includes keeping the powder dry in tightly sealed containers. Common usage rates for soil stabilization, for example, vary between 2% and 6% by weight depending on soil conditions, while for water treatment applications, dosages are typically calculated to maintain target pH levels between 7.5 and 9.5.

Industries engaged in water treatment rely on Calcium Hydroxide to achieve precise pH adjustment that facilitates removal of contaminants and protects system integrity from corrosion. Its alkaline properties make it essential to neutralize acidic waste streams, ensuring effluent compliance with environmental regulations. In construction, it improves soil properties by increasing load-bearing capacity and reducing plasticity, which directly leads to enhanced foundation stability and longevity of infrastructure projects. Without accurate dosing of Calcium Hydroxide, these critical processes risk inefficiency, equipment damage, or regulatory breaches.
