Silicon Nitride Ceramic:
In recent years, a large amount of research has been conducted on gas pressure sintering, and great progress has been made. The air pressure sintering silicon nitride is carried out at a temperature of about 2000 ° C under a pressure of 1 to 10 MPa. The high nitrogen pressure suppresses the pyrolysis of silicon nitride. Due to the high-temperature sintering, it is sufficient to promote the growth of Si3N4 grains with the addition of less sintering aids, and obtain a long columnar grain high-toughness ceramic with in-situ growth density > 99%. Therefore, gas pressure sintering is in the laboratory. It is still getting more and more attention in production. Air pressure sintering silicon nitride ceramics have high toughness, high strength and good wear resistance, and can directly produce various complex shape products close to the final shape, which can greatly Reduce production costs and processing costs. And its production process is close to the cemented carbide production process, suitable for large-scale production.
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.
