Calcium sulfate hemihydrate（Cat No.:M119936）, is a chemical compound commonly known as plaster of Paris. It is produced by partially dehydrating gypsum, a naturally occurring mineral. When mixed with water, calcium sulfate hemihydrate undergoes a rapid and controlled setting reaction, forming a hard and durable material. This property makes it valuable in construction, especially for creating casts and molds. It is used in medical applications for casting broken bones and dental impressions. Additionally, it is used in art and sculpture.
