chemical stability silicon nitride Si3N4 ceramic rod bar
Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
For the Si3N4 and Sialon ceramic sintered bodies, a process of molding by superplasticity which maintains a single state without forming a composite material has been provided, and a sintered body formed according to the process is provided. a silicon nitride and a Sialon sintered body having a relative density of 95% or more and a linear density of 50 μm in a two-dimensional cross section of the sintered body in a range of 120 to 250; by stretching at a temperature of 1300 to 1700 ° C or The compression causes plastic deformation at a strain rate of less than 10-1 / sec to perform molding. The sintered body after molding has excellent mechanical properties particularly at normal temperature.
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
