Silicon nitride
Has high strength. Especially hot-pressed silica nitride which is one the hardest materials on the planet. It can withstand temperatures up to 1200degC and maintain its strength. After heating, it will not turn into a melted substance and won’t decompose till 1900degC.
Silicon nitride resists chemical corrosion with amazing strength. It is resistant against almost all organic and inorganic acid solutions. It’s also a highly-performance electrical insulation material.
Ceramics made of silicon nitride have many excellent properties. They are used for bearings as well as turbine blades.
(1) Application to ironmaking refractories
Recent years have seen significant improvements in the corundum-silicon-carbide-silicon-nitride products used for large-scale blast-furnaces. In the middle section and load-bearing part of coke kilns, large blast furnaces are commonly made from silicon oxynitride refractory materials, or silicon carbide.
2) Application in steelmaking Refractories
The bottom ladle material has been made of silicon nitride in recent years. The addition of a silicon nitride slide plate material improves wear resistance and erosion resistance of the slide, as well as the service life and cost of steel per tonne of ladle refinement.
(3) Application to refractory smelting non-ferrous metals, such as copper, aluminum, zinc, etc.
Silicon nitride does not wet metal solutions at high temperature, so it is suitable for high-temperature products in the nonferrous metal smelting processes, such as thermowells. Smelting furnace linings. Container linings. Crucibles. Silicon nitride ceramic products have good thermal shock resistance and can be used stably for a long time at high temperatures or in high-temperature-low-temperature cycles.
(4) Application in kiln furniture materials
The ceramic shed consists of a silicon-nitride-bonded silicon carbide prepared by reaction sintering at high temperatures in nitrogen atmosphere, with silicon carbide powder as the raw material. Fine metal Si powder is also used. This material has a greatly improved performance.

Silicon Nitride as a Refractory Material
The excellent high temperature properties of silicon nitride are considered to make it a promising material for high-temperature structures. These include high high-temperature strengths, corrosion resistance and good wear resistance.(1) Application to ironmaking refractories
