Effects of plaster to water ratio on physical and mechanical properties of ceramic pieces produced by the slip casting process

Abstract In the slip casting process, the relationship between the amount of plaster and water used in the production of molds influences the production of ceramic materials, because the higher the water content in the mixture, the lower the mechanical strength of the mold and higher the water absorption rate. In order to evaluate the influence of the variation in the plaster/water (P/W) ratio in the production of ceramic pieces, plaster molds with P/W ratios of 2.0, 1.67, 1.43, and 1.25 (100 parts of plaster/50, 60, 70, and 80 parts of water by weight) were manufactured and used in the produc...
