Measurements of the phase transformation temperature of gypsum-anhydrite, included in quartz, by microthermometry and Raman microprobe techniques. Reaction of this partially or completely dehydrated gypsum with water leads to a setting and crystallization reaction which is the base of working as a binder. Anhydrite is orthorhombic and does not react with hydrochloric acid. Anhydrite is a hard crystal with a hardness rating of 3.5 and approximate density of 3.0. At room temperature, insoluble anhydrite dissolves very slowly to the extent of 0.24 g per 100 g of water and does not absorb moisture from the air. 3 2H2O) into Anhydrite(CaSO4) is a reveresible reaction .Gypsum with aqueous salt solutions transformed to anhydrite at 90.5C because of the sediment l. What Type Of Reaction Is Gypsum -> Anhydrite? If gypsum had been completely dissolved prior to calcite precipitation, the mesh would not have been able to form a self-supporting structure and so would have collapsed to the floor of the pore.
