Product Introduction

Silicon Nitride Si3n4 Description

The process of preparing silicon nitride ceramic products generally consists of raw material treatment, powder synthesis, powder treatment, molding, billet treatment, sintering and ceramic body treatment. The type of silicon nitride ceramic preparation process is mainly distinguished by the different methods and sequences of synthesis, molding and sintering.

Ceramics commonly used molding methods are dry pressing, casting and injection, of which dry pressing molding is a widely used molding process, dry pressing molding, also known as molding, is one of the commonly used molding methods. Dry compression molding is after granulation of good fluidity, particle gradation of the appropriate powder, loaded into the metal mold cavity, through the pressure exerted by the indenter, indenter displacement in the mold cavity, transfer pressure, so that the powder particles in the mold cavity rearrangement deformation and compaction, the formation of ceramic blanks with a certain strength and shape.
