Alumina Wafer Polished Refractory Insulation Hardness Wear Resistant Ceramic Wafer

Advantages of Alumina Wafers:

A.  Refractory.

B.  Self Lubricating

C.  Long Service Life.

D.  Good Polished Surface.

E.  Environmental and Healthy.

F.  Superior Mechanical Strength.

G.  High Corrosion and Wear Resistance.

H.  Good Insulation Performance Precision.

I.    High Temperature and Pressure Resistance.

J.   High Purity Zirconia and Alumina Ceramic Material.

 

Alumina Wafer is kind of structural ceramics, with insulation resistance, voltage resistance, high strength, good thermal conductivity, dielectric loss, stable electrical performance characteristics.

 

Alumina Wafer Used in electronic ceramic substrates, ceramic electrical insulation, vacuum devices, devices porcelain, spark plugs and other products. We can make the part by hot injection pressing, dry pressing, isostatic pressing and extrusion productive technology etc.

Main Applications

       A.  Substrates for thin film circuits

       B.  Sensor component substrates

       C.  Substrates for semiconductor processing

Features

         A.   Able to manufacture up to a maximum size of φ400 mm (φ16 inch).

        B.    The material has a low surface roughness (Ra 0.02μm or less) and few surface pores which makes it possible to form fine circuit      patterns.

         C. The high bending strength allows a reduced thickness.

         D. The small dielectric loss tangent in the high frequency band makes it ideal for use with high-frequency circuits.
