Material Introduction

Silicon Nitride (Si3N4) has the most versatile combination of mechanical, thermal, and electrical properties of any technical ceramic material. It is a high performance technical ceramic that is extremely hard and has exceptional thermal shock and impact resistance. It surpasses most metals high temperature capabilities and has a superior combination of creep and oxidation resistance. Additionally, its low thermal conductivity and high wear resistance make it an excellent material that can withstand the toughest of conditions in the most demanding industrial applications. Silicon Nitride is an excellent choice when high-temperature and high-load abilities are needed.

Product Features

√ low density, low weight	√ greatly electrical insulation
√ non-wetting to non-ferrous metals	√ high hardness, high wear resistance
√ low coefficient of thermal expansion	√ outstanding resistance to thermal shock
√ maximum service temperature up to 1,200 °C	√ superior corrosion resistance to molten metals
