Si3N4 silicon nitride ceramic block brick customized

Reputation depends on quality,  quality comes from Hard!


Machinable Glass Ceramic:

The Si3N4 ceramic material is subjected to a high temperature pre-oxidation treatment at 1400-1500 °C to form a Si2N2O phase on the surface of the ceramic material, which can significantly improve the oxidation resistance and high-temperature strength of the Si3N4 ceramic. The mechanical properties of the Si3N4 ceramic produced by the hot press sintering method are superior to those of the reaction-sintered Si3N4, and the strength is high and the density is high. However, the manufacturing cost is high and the sintering equipment is complicated. Due to the large shrinkage of the sintered body, the dimensional accuracy of the product is limited, it is difficult to manufacture complicated parts, and only parts with simple shapes can be manufactured, and the machining of the workpiece is difficult.

properties:

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.
