Usage

Description

Calcium sulfate, also known as plaster of Paris or gypsum, is a naturally occurring chemical compound consisting of calcium, sulfur, and oxygen. It is widely found in nature as the mineral gypsum and is also produced as a byproduct of various industrial processes, such as flue gas desulfurization in power plants. With its diverse properties, calcium sulfate has a broad range of applications across different industries.

Uses

Used in Construction Industry:
Calcium sulfate is used as a building material for making plaster and drywall. Its ability to set quickly and adhere well to surfaces makes it an ideal component in the construction industry.
Used in Food Industry:
In the food industry, calcium sulfate is used as a food additive, specifically in the form of calcium sulfate dihydrate. It serves as a firming agent, helping to maintain the texture and stability of various food products.
Used in Agriculture:
Calcium sulfate is used as a soil conditioner in agriculture. It helps improve the soil structure and fertility by providing essential calcium and sulfur nutrients, promoting healthy plant growth.
Used in Tofu Production:
In the food industry, calcium sulfate is used as a coagulant in tofu production. It aids in the formation of tofu by causing the proteins in soy milk to coagulate and form a gel-like structure.
Used in Medical Applications:
Calcium sulfate has medical uses, such as in the treatment of bone fractures. Its ability to promote bone healing and provide structural support makes it a valuable component in orthopedic applications.
Used in Dental Applications:
