Low-iron calcium hydroxide (chemical formula: Ca(OH)₂), commonly known as hydrated lime or slaked lime, is a high-purity inorganic white powder with ultra-low iron impurities.It features a whiteness of over 93% and a dry-basis purity of ≥95%, with high-end specifications reaching more than 98%.Manufactured from high-quality limestone through precise calcination, hydration and refined purification processes, the product has fine and uniform texture, no caking and good fluidity. It is slightly soluble in water with a strongly alkaline aqueous solution and excellent chemical reactivity and adsorption capacity.The core advantage of low-iron calcium hydroxide lies in its extremely low iron content, which effectively prevents adverse effects of iron ions on color, stability and subsequent chemical reactions, and avoids yellowing, discoloration and side catalytic reactions. It is specially applicable to high-end fields sensitive to iron impurities.Widely used in food processing (sugar refining, bean products, beverage pH adjustment), pharmaceutical synthesis, fine chemicals, high-grade papermaking, electronic materials, premium coatings, water treatment and other industries.
