The issues of improvement and optimization of the properties and structure of porous molds used in the ceramic industry are still relevant. In this work, plaster materials based on the mix of α- and β-calcium sulfate hemihydrate (α-CaSO4·0.5H2O, β-CaSO4·0.5H2O) were received and their properties were studied. Based on the test results of the strength characteristics, water adsorption and kinetics of formation process, the optimum composition of gypsum binder was proposed for application in technical ceramics production.
