Calcium Sulfate Dihydrate (CaSO₄·2H₂O), commonly known as gypsum, is an inorganic compound whose fundamental chemical properties underpin its vast array of industrial, agricultural, and medical applications. As NINGBO INNO PHARMCHEM CO.,LTD., a leading China-based chemical manufacturer, we understand that a deep appreciation of these properties is key to leveraging gypsum effectively. Our commitment to producing high-purity Calcium Sulfate Dihydrate ensures that clients receive a product whose characteristics meet stringent application requirements.
Structurally, Calcium Sulfate Dihydrate crystallizes in the monoclinic system, forming soft, often tabular or prismatic crystals. Its molecular weight is approximately 172.17 g/mol. The compound is characterized by layers of calcium (Ca²⁺) and sulfate (SO₄²⁻) ions held together by hydrogen bonds involving water molecules. This structure dictates its physical properties, including its perfect cleavage and Mohs hardness of 1.5–2, making it a relatively soft mineral.
One of the critical chemical properties of gypsum is its solubility. It is slightly soluble in water, with solubility decreasing at higher temperatures (retrograde solubility), unlike many other salts. This characteristic influences its behavior in aqueous solutions and its effectiveness in applications like soil conditioning where gradual nutrient release is desired. The phrase 'chemical properties of calcium sulfate' often relates to this nuanced solubility.
When heated, Calcium Sulfate Dihydrate undergoes dehydration. At temperatures around 150°C, it loses about three-quarters of its water to form calcium sulfate hemihydrate (CaSO₄·½H₂O), known as plaster of Paris. Further heating to above 200°C results in anhydrous calcium sulfate (CaSO₄), or anhydrite. This thermal behavior is fundamental to its use in creating setting materials like plaster casts and drywall. Understanding these chemical transformations is vital for manufacturers looking to buy gypsum.
Gypsum is generally stable but can react with strong acids. Its low reactivity and non-toxic nature, especially when refined to food or pharmaceutical grades, make it a safe ingredient for many uses. NINGBO INNO PHARMCHEM CO.,LTD. focuses on producing gypsum with controlled purity and minimal impurities, ensuring optimal performance in applications ranging from industrial fillers to sensitive food products. Our role as a supplier of calcium sulfate dihydrate CAS 10101-41-4 is built on providing a chemically sound and reliable product.
In conclusion, the chemical properties of Calcium Sulfate Dihydrate – its structure, solubility, thermal dehydration, and reactivity – are the foundation of its widespread utility. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing gypsum of exceptional quality, enabling industries to harness these properties for innovation and efficiency.
