Product Description

Silicon Nitride Protection Tube is our main popular products. It has good performace on thermal shock resistance, oxidation resistance, thermal shock resistance.  We have standard sizes in stock and also could supply customized sized as per your request.

Features of Silicon Nitride Protection Tube

Silicon Nitride Protection Tube also has good chemical stability and excellent resistance to acid and alkali. It can withstand high temperatures with no significant reduction in material strength. Its high thermal conductivity is 5 times higher than that of stainless steel. This product uses testing equipment for strict testing of products to ensure the quality and longevity of the products.

Sintering Method

Hot Press Sintering process description

The hot press sintered Si3N4 ceramic used by some companies in the United Kingdom and the United States has a strength of more than 981MPa. Additives and phase composition during sintering have a great influence on product performance. Due to the strict control of the composition of the grain boundary phase and proper heat treatment after the Si3N4 ceramic is sintered, it is possible to obtain Si3N4 ceramic materials whose strength (up to 490 MPa or more) does not decrease significantly even at temperatures as high as 1300 ℃, and is also resistant to creep Denaturation can be improved by three orders of magnitude. If the Si3N4 ceramic material is pre-oxidized at a high temperature of 1400-1500 ℃, a Si2N2O phase will be formed on the surface of the ceramic material, which can significantly improve the oxidation resistance and high temperature strength of the Si3N4 ceramic.
