An improved method for simplifying a slip casting appliednconventional all ceramic core molding process by molding an allnceramic core from a ceramic sheet. In the method, there is preparedna slurry which consists mainly of alumina, spinel,nalumina/zirconia powder, by adding thereto a dispersant, anbinding agent, a plasticizer, a solvent and the like. The slurrynis formed into a sheet having a thickness of 0.1mm to 1.0mm fornthereby fabricating a tooth molding mass by using a heatnhydrostatic pressing at a pressure of 15 Kgf/cm 2 to 150 Kgf/cm 2 atna temperature of 50°C to 110°C, with slurry composition fornfabricating an all ceramic jacket crown applicable to annartificial crown comprises. |
