Manufacturing method for non crazing heat resistant ceramic pottery and non crazing heat resistant ceramic pottery thereby

摘要

The present invention relates to a method for producing a heat-resistant, non-cracking heat resistant magnet, which comprises the steps of forming a material by a molding method such as a spinning method, a molding method, a casting method or the like, The surface of the fired material is coated with a ceramic coating agent and heat treated to produce a heat-resistant self-heating magnet. According to the present invention, since there is no crack in the surface coating layer of the heat-resistant magnetic material, the food can be easily cleaned without sticking to the food during cooking, and the pores and the surface irregularities are formed in the heat- And the adhesion between the surface of the heat resistant magnetic body and the coating layer is excellent, so that the coating layer is not desorbed or damaged even if it is used for a long period of time.
