Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O.

The hemihydrate (x=~0.5) is commonly known as plaster of Paris. The dihydrate (x=2) occurs as a mineral known as gypsum. Calcium sulfate can be used as a high temperature oxidizer in orange color compositions. Excellent strobe compositions can be made with it.

Terra alba is a natural gypsum that can be used as an extender in paint and filler in grounds. Terra alba, calcium sulfate dihydrate, is made by fine grinding and air separating a select, high purity, white gypsum from Italy containing about 20% water of crystallization.

Naturally occurring or man-produced calcium sulfate dihydrate is subjected to a process which involves concomitant flash calcination, utilizing co-current contact of the gypsum with a gaseous heat source, and self-comminutation to produce the insoluble calcium sulfate anhydrite in relatively pure and finely comminuted form without the use of specially-sized feed rock and extensive mechanically ...

Calcium sulfate (1:1) 136.14 Dihydrate 172.17. Calcium Sulfate is anhydrous or contains two molecules of water of hydration. It contains not less than 98.0 percent and not more than 101.0 percent of CaSO4 i.e. Calcium Sulfate or Calcium Sulphate, calculated on the dried basis. Labeling— Label it to indicate whether it is Calcium Sulfate ...

It is still uncertain whether β-hemihydrate and dihydrate gypsum influence the properties, especially the phase conversion, of white calcium aluminate.

The calcium sulfate dihydrate phase was the major component found in the diffractograms of all generated samples after hydration, as displayed in Figure 10. This indicates that the samples were well hydrated as no hemihydrate or anhydrite phases were discovered. However, the intensity of the peaks differs slightly in length and positions.

At 20C (68F), calcium sulfate dihydrate – the form most commonly available – has a solubility of around 2.4 g/L. In practice this means that you can have up to around 550 ppm of Ca in solution from calcium sulfate dihydrate before you observe any precipitation happening.

Calcium sulfate dihydrate, therefore, is one part calcium sulfate and two parts water. b. Properties. In the manufacturing process, gypsum is converted to plaster of Paris and artificial stone by a process called calcining. The gypsum is first ground to a fine powder of particle size. Plaster of Paris is derived when the gypsum is subjected to ...

USG Terra Alba-F&P Grade, the dihydrate form of calcium sulfate, is made by fine-grinding and air-separating a select, high-purity white gypsum containing about 20% water of crystallization. U.S. Gypsum Calcium Sulfate products serve the food, beverage, and pharmaceutical industrial as industries as an economical source of supplemental calcium.

Anhydrite is a mineral from the Calcium Sulphate family (CaSO4). Anhydrite is an anhydrous compound - it does not contain water in its crystal structure, unlike other minerals. Anhydrite is a unique material with outstanding properties beneficial to many industrial applications.

Selenite, also known as satin spar, desert rose, or gypsum flower are four crystal structure varieties of the mineral gypsum.These four varieties of gypsum may be grouped together and called selenite. All varieties of gypsum, including selenite and alabaster, are composed of calcium sulfate dihydrate (meaning that it has two molecules of water), with the chemical formula CaSO 4 ·2H 2 O ...

Food and Pharmaceutical Grade. The ACG Food andPharmaceutical Calcium Sulfate Dihydrate, is a very fine, free-flowing, odorless, tasteless white powder produced by fine-grinding and air separating a select grade of high-purity white gypsum that is safe for use in food products as outlined in 21 CFR 184.1230 (April, 1986).

Gypsum, made up of 21% calcium and 17% sulfate, is one of the best sources of calcium for every plant in your garden. While many gardeners tend to rely on limestone to provide a rich source of calcium, limestone is not water soluble and must come into contact with soil acids before the calcium ions are released to plant roots.
