Explanation

In the process of dental porcelain fused to metal (PFM), the powder porcelain used to make the PFM prosthesis is processed by sintering. According to its composition and properties, it can be divided into feldspathic ceramic powder and alumina ceramic powder; according to melting point, it can be divided into high melting ceramic powder, medium melting ceramic powder and low melting ceramic powder. feldspar porcelain powder includes body porcelain and enamel. Body porcelain is mainly composed of feldspar, quartze, white clay, borax, silica, alumina, colorant, binder, etc. Glazed porcelain is mainly composed of quartze and borax. The porcelain fused to metal prosthesis made of porcelain powder has excellent physical and chemical properties, good optical properties, stable color, good biological properties, and the disadvantage is insufficient mechanical strength. The manufacturing of porcelain fused to metal powder mainly goes through the process steps of batching, grinding, sintering, quenching, milling, packaging, etc. porcelain powder is suitable for dental production of porcelain crowns, inlays, etc.
