Alumina Ceramic
Alumina ceramic is a kind of material based on alumina(AI2O3),which is used in thick film integrated circuit.Alumina ceramics have good conductivity,mechanical strength and high temperature resistance.It needs to be noted that ultrasonic cleaning is needed.Alumina ceramic is a kind of widely used in modern society,meeting the needs of daily use and special performance.
Zirconia Ceramic
Zirconia ceramics is a kind of ceramic material based on zirconia.In terms of structural ceramics, zirconia is different from traditional ceramics. Zirconia has very high strength, wear resistance and flexibility, which far exceeds most other technical ceramics. Zirconia is a very strong industrial ceramic with excellent properties in hardness, fracture toughness and corrosion resistance. Compared with metals,in daily use special ceramics have the characteristics of non-rusting, non-magnetic, wear resistance and insulation, so zirconia ceramics have high toughness, high bending strength and high wear resistance, as well as excellent thermal insulation and Coefficient of thermal expansion similar to steel, so it is widely used in the field of structural ceramics.
Silicon Nitride Ceramic
Silicon nitride ceramic material has the characteristics of high hardness, low density, wear resistance and high temperature resistance. It is an inorganic material ceramic that does not shrink when sintered.Therefore, it has been regarded as the material for making high speed and precision bearings.
