Special Performance Gypsum Board Has Come A Long Way. F rom its initial introduction in the 1890s to mainstream usage by the 1950s, gypsum wallboard has become the primary interior partition covering and finishing surface for both residential and commercial construction. In the process, this costefficient, easytoinstall building material has experienced continuous development and
Gypsum, common sulfate mineral of superb industrial significance, composed of hydrated calcium sulfate (CaSO4 #183;2H2O). In properlydeveloped crystals the mineral normally has been called selenite. The fibrous large variety has a silky lustre and is known as satin spar; it is translucent and opalescent and is valued for ornaments and jewellery.

The term quot;synthetic gypsumquot; has been used widely to encompass materials produced by a variety of industrial processes. In addition to FGD gypsum, synthetic gypsum includes materials such as phosphogypsum, (a byproduct of processing phosphate ore to make phosphoric acid), Titanogypsum (a byproduct from the production of titanium dioxide), fluorogypsum (a byproduct from the production of
The physical properties of the two gypsum powders are different. The type gypsum powder has good crystallinity and solidity, so it can be used in ceramic molds, sculptures, gypsum lines and highend buildings. The type gypsum powder is mainly used for mortar levelling, gypsum board production
#0183;#32; Not all gypsum products display all of these desirable properties equally. Types of Gypsum Products Gypsum products are made from gypsum rock, which is a mineral found in various parts of the world. Gypsum rock is mined, ground into a fine powder, and then processed by heating to form a variety of products.

#0183;#32;Gypsum Gypsum is a useful mineral material. It is extensively applied as construction material, most of which is produced as plaster for painting walls or making decorative material in buildings. Some gypsum ore deposits contain about 80% gypsum, which is excellent for producing plaster. Raw gypsum ore could be processed into a variety of products
#0183;#32;Gypsum is heated to about 300 degree Frenheit to produce plaster of Paris, which is also known as gypsum plaster. It is mainly used as a sculpting material. Gypsum is used in making surgical and orthopedic casts, such as surgical splints and casting molds.
