Produced through the hydration of calcium oxide (quicklime), it is renowned for its strong alkaline properties and versatility across various industries.Key FeaturesHigh Purity: Food-grade calcium hydroxide boasts a purity level of ≥98%, ensuring suitability for sensitive applications.Fine Particle Size: Typically processed to pass through a 325-mesh sieve, resulting in a superfine powder that enhances reactivity and dispersion.Low Impurities: Stringent refining processes reduce heavy metals and other contaminants to meet international food safety standards.Stable pH: Exhibits a consistent pH of approximately 12.4 in a 1% aqueous solution, making it effective for pH adjustment applications.Technical SpecificationsParameterSpecificationParamaterSpecificationPurity (Ca(OH)2)≥ 95.0%Fe≤ 0.05Calcium Oxide (CaO)Approximately 73.0%Moisture Content≤ 0.12%Calcium Carbonate (CaCO3)≤ 1.7%pH (1% solution at 25°C)12.4–12.6Magnesium Oxide (MgO)≤ 0.35%Density2.24 g/cm3Acid Insoluble Matter≤ 0.1%SolubilitySlightly soluble in water; soluble in glycerol and acids; insoluble in alcoholHeavy Metals (as Pb)≤ 0.002%Mesh Size≥ 95% passing 325 meshProduct ApplicationCalcium hydroxide, also known as hydrated lime, is widely used across various industries due to its strong alkalinity, reactivity, and purity. It plays a key role in environmental treatment, such as wastewater neutralization and heavy metal removal. In flue gas desulfurization, it serves as an effective sorbent for SO2 control in power plants and industrial boilers. The construction industry uses it in the formulation of mortar, lime plaster, and as a cement additive. In the chemical sector, it is used for producing calcium salts, petroleum additives, and rubber processing agents. Food-grade calcium hydroxide (E526) is also applied in the food industry as a pH regulator for products like candies and beverages. Additionally, ultra-high purity grades are used in electronic applications, including high-end chemical synthesis and slurry formulations.Company ProfileCHANGSHU HONGYU CALCIUM Co., Ltd.Changshu Hongyu Calcium Co., Ltd., a specialized manufacturer of high-purity calcium compounds based in Jiangsu, China.
