FAQs of Calcium Sulphate:

Q: How is calcium sulphate dihydrate manufactured?

A: Calcium sulphate dihydrate is typically obtained from natural gypsum or synthesized by reacting calcium carbonate with sulfuric acid. This process ensures high purity suitable for industrial and pharmaceutical applications.

Q: What are the main industrial usages of calcium sulphate dihydrate?

A: It is used in the production of plaster of Paris, construction materials like drywall and cement, as a food additive (E516), a pharmaceutical excipient, and a soil conditioner to improve soil structure.

Q: When does calcium sulphate dihydrate decompose, and what does it form?

A: Calcium sulphate dihydrate decomposes upon heating at approximately 145C, forming the hemihydrate known as plaster of Paris, which is widely used in construction and medical casting.

Q: Where should calcium sulphate dihydrate be stored to maintain its quality?

A: It should be stored in a cool, dry place at room temperature, away from moisture, to prevent premature decomposition or clumping, ensuring product integrity.

Q: What is the benefit of using calcium sulphate dihydrate in food processing?

A: As a food additive (E516), it acts as a coagulant in tofu and other products, aiding in texture formation and stability, while being safe and compliant with food standards.

Q: Is calcium sulphate dihydrate soluble in water or alcohol?

A: Calcium sulphate dihydrate is slightly soluble in water (2.1 g/L at 25C) and insoluble in alcohol, allowing controlled application in industrial and food processes.

Q: How does calcium sulphate improve soil quality in agriculture?

A: In agriculture, calcium sulphate conditions soil by improving structure, reducing compaction, and supplying essential calcium and sulfur nutrients for plant growth.
