Gypsum is a mineral consisting primarily of calcium sulfate dihydrate ($\text{CaSO}_4 \cdot 2\text{H}_2\text{O}$). It is widely used in various industrial applications due to its characteristic properties, notably its ability to readily undergo dehydration and chemical reaction when heated or mixed with water. When heated, the mineral loses its bound water molecules, forming anhydrite, which changes its physical characteristics. Industrially, it is a vital component in the production of various binding materials and plasters. Furthermore, the mineral's chemical composition makes it useful in certain chemical processes and as a source of sulfates in scientific experimentation, making it significant in the fields of materials science and chemistry.
