SECTION 10: Stability and reactivity
10.1 Reactivity
No rapid reaction with air No rapid reaction with water
10.2 Chemical stability
no data available
10.3 Possibility of hazardous reactions
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).
10.4 Conditions to avoid
no data available
10.5 Incompatible materials
Many metal oxo-compounds (nitrates, oxides and particularly sulfates) and sulfides are reduced violently or explosively (ie undergo 'thermite' reaction) on heating an intimate mixture with aluminum powder to a suitably high temperature to initiate the reaction. Sulfates, including calcium sulfate
