Two types of gypsum plasters are used to formulate underlayment products: alpha and beta. These terms describe the two crystal forms of calcium sulfate hemihydrate (the chemical name for plaster of Paris). The material we now call beta hemihydrate has been used for thousands of years and until the 1920s was the sole material used to create all ...
Alpha Gypsum is obtained by heating of gypsum stone under high pressure and Alpha Gypsum is chemically same with / 2H2O formula and beta gypsum but different from in the point of crystal structure. Structure of beta gypsum is needlelike and amorphous while crystal structure of Alpha Gypsum is geometric.
