Air and Water Reactions:No rapid reaction with air No rapid reaction with water
Reactive Group:Salts, Basic
Reactivity Profile:CALCIUM SULFATE is non-combustible. Decomposes to give toxic oxides of sulfur, but only at very high temperature (>1500°C). Generally of low reactivity but may act as an oxidizing agent: incompatible with diazomethane, aluminum, and phosphorus. Certain forms of calcium sulfate react with water; others do not. INSOLUBLE ANHYDRITE or dead-burned gypsum is made by the dehydration of calcium sulfate dihydrate (gypsum) at high (> 600°C) temperature. 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. SOLUBLE ANHYDRITE, which is obtained by heating calcium sulfate dihydrate at a temperature below 300°C, has a high affinity for water and is used as a desiccant. Soluble anhydrite absorbs water to form calcium sulfate hemihydrate (Plaster of Paris).
Flammable Limits:Noncombustible Solid
