Study of Gypsum Dehydration Time in CaCl2 Solution

The preparation of the alpha form of calcium sulphate hemihydrate is technically relatively complicated The idea is to allow 15 molecules of water contained in gypsum to leave through dehydration in liquid form This can only be achieved under hydrothermal conditions, namely in an autoclave or by increasing the boiling point of the solution in which the gypsum is located during dehydration...
