Product DescriptionCaO is an efficient and commonly used desiccant widely used in food industry, industry, and agriculture.Calcium oxide (CaO) undergoes a vigorous chemical reaction with water to form calcium hydroxide and release a large amount of heat, thereby absorbing moisture in the environment. The reaction formula is as follows:CaO + H2O = Ca(OH)2 + HeatThis reaction is irreversible and achieves thorough water absorption (approximately 0.32 parts of water can be absorbed by 1 part of calcium oxide). Additionally, the calcium hydroxide formed after water absorption is in a stable solid state, which is not prone to reabsorbing moisture, ensuring long-lasting drying effectiveness.The exothermic nature of the reaction can also accelerate water evaporation, indirectly enhancing the drying efficiency. SpecificationProduct InformationCAS Number: 1305-62-0Molecular Formula: Ca(OH)2Molecular Weight: 74.09 g/molAppearance: White or off-white odorless powderSynonyms: Slaked Lime, Hydrated Lime, Calcium HydroxideProduct OverviewHydrated lime, chemically known as calcium hydroxide (Ca(OH))2, is a versatile and essential industrial chemical with a wide range of applications across multiple sectors. Our company is committed to providing high - quality hydrated lime products that meet and exceed international standards, ensuring reliability and performance for our customers worldwide.Key FeaturesHigh purity calcium hydroxide (Ca (OH)2, commonly known as slaked lime) has irreplaceable application value in fields with strict requirements for purity and performance due to its high purity (usually ≥95%), extremely low content of impurities (such as heavy metals, acid-insoluble substances, etc.), and strong reactivity.The application essence of high-purity calcium hydroxide is to utilize its high alkali purity, low impurity interference, and strong reaction controllability to achieve functions that traditional lime cannot replace in the chemical industry, environmental protection, food and medicine, and other fields. With the improvement of industry standards, its application scenarios will continue to expand towards high-end and refined directions.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.
