Product Description

Silicon Nitride Si3N4 Ceramic Disc For Sintering

The description of the Si3N4 ceramic disc

Silicon Nitride (Si3N4) is a widely used technical ceramic material in high temperature application, it has high strength in both room temperature and high temperature condition, the strength of silicon nitride can be kept up to 1200℃; the low coefficient of thermal expansion make it a ceramic material possessing excellent thermal shock resistance; at the same time, it also has good thermal conductivity.
Except for the excellent properties in thermal application, silicon nitride also has good mechanical, chemical, electrical properties. It has good strength, good flexture strength and wear resistance;it is a good performance electrical insulation ceramic

The specification of the Si3N4 ceramic disc

1. We are supplying with many round ceramic wafer, square & rectangular Ceramic Substrate
2. The typical thickness of silicon nitride substrate covers 0.30mm, 0.5mm, 0.635mm, 1.0mm
3. The biggest diameter of round ceramic wafer can be up to 400mm in 3mm, 4mm, 5mm thick
4. The max. side-length of square and rectangular ceramic substrate can be 400mm by 500mm
5. Surface treatment: it can be one-side, or double side polished to be Ra0.4 or better

The main features of the Si3N4 ceramic disc
1. High thermal conductivity ( up to 70 W/m.k), 3 times that of Alumina Ceramic Substrate;
2. The bending strength is higher than that of the alumina substrate,
which is twice that of the alumina substrate;

3. The thermal expansion coefficient (3.1×10-6/℃) matches the semiconductor silicon material (3.5-4.0×10-6/℃);
4. Excellent electrical performance, with extremely high insulation resistance and low dielectric loss;
5. The compatibility of circuit materials is good, and multi-layer wiring can be performed to achieve miniaturization of the package;
6. High thermal shock resistance, from 0 ℃ to 200 ℃ and then cool down, repeat 10000 times;
7. Chemical resistance, resistant oxidization , acid, alkali corrosion, service life-span up to 10 years.


The application of the silicon nitride ceramic parts
Silicon nitride ceramics are widely used for precision shafts and axles in high wear environments,rotating bearing balls and rollers,cutting tools, engine wear parts, tappet shims,turbine blades, vanes, buckets, metal tube forming rolls and dies.
