Silicon Nitride Si3N4 Ceramic

Silicon Nitride (Si3N4) is a relatively costly, high-temperature, structural ceramic
used where heat resistance, hardness, and strength are a premium.
It is very hard, and therefore can be used in high wear applications or applications requiring a fine surface polish.
Silicon Nitride is fabricated using either sintering, reaction bonding, hot pressing, or hot isostatic pressing.
The material properties resulting from these processes vary considerably

it is one kind of technical ceramic materials which has very good performance in high temperatrue.

Its mechanical strength can be kept up to 1200ºC. Its hardness and wear resistance performance ranks high
among all technical ceramic materials.

It has high electrical resistivity, high dielectric constant and low dielectric loss, is a choice for electrical insulation.

Furthermore, it has good chemical stability and resistance to oxidation.

As a result, silicon nitride ceramic has the best comprehensive performance and most wide application in high
temperature field.
