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 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
