Description

There are countless chemical compounds in the world that are vital to human life. One of the most widely used of these chemical compounds is calcium sulfate, which is formed by the bonding of a number of calcium elements with the chemical symbol Ca, a sulfur element with the chemical symbol S, and four oxygen elements with the chemical symbol O. The chemical in question is considered to be the main cause of water hardness. Calcium sulfate is used to regulate the hardness of water for a variety of processes. Shanghai Chemex is one of the most reputable suppliers of this chemical in the world.

Physical and Chemical Properties of Calcium Sulfate:

In general, calcium sulfate is a solid substance that has a powdery state and appears as a crystalline white color. This chemical product has no odor ‌ and is a stable substance at room temperature. The most important physical and chemical properties of this compound can be summarized in the following table:

Chemical Structure Depiction chemical structure of calcium sulfate

Chemical Formula of Calcium Sulfate:

The chemical formula of calcium sulfate is CaSO4. It is composed of calcium cation and sulfate anion, which form an orthorhombic or monoclinic structure. Calcium sulfate has three hydrated forms: anhydrous, dehydrated, and hemihydrate.

Is Calcium Sulfate Soluble or Insoluble?

The physical properties of the three forms of calcium sulfate are different, but their chemical properties are the same. Calcium sulfate is insoluble in water without water, but both dehydrate and hemihydrate are slightly soluble in water.

Production and Synthesis of Calcium Sulfate:

The main sources of calcium sulfate are gypsum and anhydrite, which are mined. In addition to natural resources, this material is obtained as a by-product in the production of several products.

  1. As a by-product in the production of phosphoric acid from phosphate rock, hydrogen fluoride and refining on calcium sulfate precipitate are also obtained.
  2. Calcium sulfate is also a common precipitate in industrial heat exchangers because its solubility decreases with increasing temperature.

Calcium Sulfate Uses:

  • Gypsum is used in the production of molds that contain hard and complex shapes.
  • This combination is widely used in sculpture and decor.
  • Calcium sulfate is used in the production of pigments.
  • This compound is used as an additive agrochemical due to its sufficient calcium and sulfur for plant growth in arable lands.
  • Used in cement production and as a filler in paper production
  • This compound is also used as a raw material in the synthesis of other calcium compounds and the production of plaster Paris.

Calcium Sulfate in Food:

Pure calcium sulfate is widely used as a food additive in the food industry. It is a natural source of calcium, a pH regulator, and an anticoagulant, found in many foods such as bread, pasta, and animal foods. like Calcium propionate

    Is calcium sulfate good for bones?

    • china chemicals – 06/06/2022

      Calcium sulfate is an easily available, economic bone graft substitute. It is a bio-inert material that over a period of weeks gets resorbed and fibrovascular tissue takes its place which eventually allows neovascularization and bone formation within the area.
