Mineral Trioxide Aggregate (MTA)

Calcium Sulfate Submicron: Calcium sulphate (CaSO4) occurs in nature in both the anhydrous and the hydrated form. It is found firstly as the mineral known as anhydrite, however the latter is apparently best known as alabaster or gypsum. Calcium sulphate also exists in forms known as selenite, terra alba, satin spar, satinite, and light spar.

Calcium Sulfate Submicron: It is only slightly soluble in water. It is permitted as a food additive in most foods with no other restriction other than good manufacturing practice. It is intended to be used in food supplements as an alternative source of calcium. Calcium sulphate is utilized as a food additive and it is used to stabilize the food. It is also utilized to firm foods and regulates their acidity levels. It is present in a different type of processed foods.

Calcium sulfates a compound of calcium and sulfate, occurring as Gysum or as plaster of paris. Calcium sulfate use in medicine and dentistry. It exists in two forms (alpha and beta), which differ greatly in physical properties. It has been used in bone regeneration as a graft material and graft binder/extender and as a barrier in guided tissue regeneration. It is an unusually biocompatible material.

Both hemi-hydrate and anhydrite are used as calcium sulphate binders for structural mortar and concrete. The benefit of using calcium sulphates instead of cement as a binder is the fact that the fabrication of calcium sulphate is more environmental friendly than that of cement.
