The porous silicon nitride ceramic material combines the excellent properties of both the silicon nitride ceramic and the porous ceramic and is a ceramic material having a communicating or closed pore in the body. Porous silicon nitride ceramics have been widely used in aerospace and environmental chemicals due to their special structure and properties, such as low density, high porosity, moderate dielectric properties, high specific surface area, high hardness, and high fracture toughness. Important fields such as biomedicine, national defense, and military.

Silicon Nitride (Si3N4) has good high temperature strength, creep resistance and oxidation resistance.
In addition, its low thermal expansion coefficient gives good thermal shock resistance compared with most ceramic materials. Silicon nitride is produced in two main ways; Reaction bonded silicon nitride (RBSN), and hot pressed silicon nitride (HPSN) and sintered silicon nitride (SSN). RBSN is made by direct reacting compacted silicon powder with nitrogen, and produces a relatively low-density product compared with hot pressed and sintered silicon nitride, however the process has only a small volume change allowing net shape forming. The HPSN and SSN material is made with sintering aids and offers better physical properties suitable for more demanding applications.

Typical Silicon Nitride applications include:

Bearing balls and rollers
Cutting tools
Valves, turbocharger rotors for engines
Turbine blades
Glow plugs
Molten metal handling
Thermocouple sheaths
Welding jigs and fixtures
Welding nozzles

Advantages

1.High hardness

2.Wear resistance

3.High fire resistance

4.Corrosion preventive

5.Good chemical stability

Ferro Silicon, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resultant alloy. Some of the primary benefits of adding Ferro Silicon to an alloy is to improve the corrosion resistant properties of the new compound, as well as to add to the high temperature heat- resistance properties of the new alloy, for example, in the production of silicon steel for use in transformer cores.

silicon nitride ceramics


Silicon nitride ceramic is an inorganic material ceramic that does not shrink during sintering. The strength of silicon nitride is very high, especially hot-pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density, high temperature resistance and other properties.
High temperature resistance, the strength can be maintained to a high temperature of 1200 without decreasing, and will not melt into a molten body after being heated, and will not decompose until 1900 It has amazing chemical corrosion resistance, and can withstand almost all inorganic acids and less than 30% caustic soda solution, as well as many organic acids; It is also a high-performance electrical insulating material.
Si3N4 can be used to manufacture ball bearings by virtue of its light weight and high rigidity. It has higher accuracy than metal bearings, generates less heat, and can operate in higher temperatures and corrosive media. The steam nozzle made of S ceramic has wear resistance, heat resistance and other characteristics, and it will not be obviously damaged after being used in 650 boiler for several months.
