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

In order to remove hydrogen in the aluminum liquid, the Silicon Nitride Ceramic hollow degassing rotor is used to feed nitrogen or argon, and the gas is dispersed by high-speed rotation,finally achieve the effect of neutralizing and discharging hydrogen.
ï?¬Compared with graphite rotor, Silicon Nitride Ceramic will not be oxidized under high temperature environment, so it will not pollute the aluminum liquid, and the service life is much longer;
ï?¬The property of high thermal shock resistance ensures that the degassing rotor will not break during frequent intermittent operation;
Because Silicon Nitride Ceramic is of high density and high strength, it assures that degassing rotor can be reliable and stable in high speed rotation.

Silicon monoxide, white cubic crystal or brown powder, is insoluble in water, soluble in a mixture of dilute hydrofluoric acid and nitric acid, reacts with boiling caustic soda solution to form silicate and hydrogen, can be oxidized by halogens, and is easily oxidized in the air to form a protective film of silicon dioxide and become inactive. It has strong reducing properties at high temperatures and can reduce water vapor, carbon dioxide, limestone and other substances; it is often obtained by sublimation of silicon dioxide and elemental silicon powder in a high vacuum above 1400�°C in industry; it is often used to prepare optical glass and semiconductor materials.
Uses Used to make optical glass and semiconductor materials. The overview, physical and chemical properties, preparation methods, and uses of silicon monoxide are edited and compiled by Ding Hong of Chemicalbook (2015-11-16) Chemical properties White cubic or loess-colored amorphous powder. When heat-treated in air, the loess-colored powder turns into white powder. Melting point is greater than 1702�°C. Boiling point is 1880�°C. Relative density is 2.13. Insoluble in water, Chemicalbook is soluble in a mixture of dilute hydrofluoric acid and nitric acid. Uses Silicon monoxide powder is extremely active and can be used as a raw material for the synthesis of fine ceramics, such as silicon nitride and silicon carbide fine ceramic powder raw materials. Uses Used in the preparation of optical glass and semiconductor materials Uses As a raw material for fine ceramics, it has important value. It can also be evaporated in a vacuum and applied to the metal reflector used in optical instruments as a protective film. It can also be used to manufacture semiconductor materials. It is also used in optical glass.
