Abstract A technology for manufacturing ceramic crucible includes such technological steps as making mould, preparing daub with qualified viscosity, coating daut on external surface of mould and spreading dry sand on it, repeating the step layer by layer until its thickness reaches a predefined wall thickness of crucible, demoulding, natural drying and high-temp. sintering. It features that there are gaps between sand particles of its wall to increase its resistance against sudden temp. variation and prevent cracking. Its advantages include long service life and low cost.
