Application note
Alumina Ceramics   (99%Al2O3---Cordierites)

Alumina ceramic is the most widely used material out of a variety of fine ceramics, it is also featured with the same crystal structure as sapphire and ruby after sintering process ( ). This material is applied to widely diversified industrial field for its superb material characteristics such as high electrical insulation, high mechanical strength, high wear and chemical resistance.

Suggested material for application
● Electrode Assembly or Insulator in BBQ Grill        95% Al2O3 / Steatite
● Lamp holder and base, electrode end insulator      95% Al2O3 / Steatite
● Mechanical Seal ring or Electron tube housing      95% Al2O3
● Valve Discs                                     95% Al2O3
● Hybrid IC Substrate                              95% Al2O3
● Crucible, Nozzle, Sagger, heat corrosion and wear resistant parts  99 % Al2O3
● Semiconductor Processing Equipment parts         Cordierite or 99.5% AL2O3

Silicon Nitride

Silicon nitride ( ) exceeds other materials in thermal shock resistance. This material does not deteriorate at high temperature, therefore it's appropriate for automotive engine and parts for gas turbine, including turbocharger rotor, glow plug of diesel engine and hot plug. It is expected that the field range this material can be applied to will widely expand.
● Molten Metal Parts
● Gas Turbine Parts

 

 

 

Silicon Carbide

Silicon carbide maintains its high mechanical strength up to as high temperature as 1,400 . Typical application is part for mechanical seal ring and pump due to higher chemical corrosion resistance than other ceramics.
● Mechanical Seal Ring
● High Temperature Resistance Parts

 

 



Zirconia Ceramics

Zirconia ceramic has high mechanical strength and toughness at room temperature out of a series of engineering fine ceramics. Zirconia was the first material adopted to fine ceramic scissors or knife application. Its excellent surface smoothness has brought this material into parts for pump products.
● Optic ZrO2 Ferrule
● Pump Parts, Knives
