Description


95% 99% Alumina Al2O3 Ceramic Disc / Cylinder / Disk / Alumina Ceramic Wafer

Tag: Alumina ceramic wafer Alumina ceramic cylinder

Large diameter Alumina Wafers

We are able to manufacture alumina wafers up to a maximum size of φ300mm (φ12 inch).
With a high density and few pores, it is possible to form fine circuit patterns.
We also handle substrates with fine rounded/square holes or slits, as well as polished substrates.

95% 99% Alumina Al2O3 Ceramic Disc / Cylinder Alumina Ceramic Wafer

Main Applications

  • Substrates for thin film circuits
  • Sensor component substrates
  • Substrates for semiconductor processing

Features

  • Able to manufacture up to a maximum size of φ300 mm (φ12 inch).
  • 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.
  • The high bending strength allows a reduced thickness.
  • The small dielectric loss tangent in the high frequency band makes it ideal for use with high-frequency circuits

7. Application: for refractory furnace or kiln, electron vacuum decices, spaceflights, pharmaceutical engineerings or other mechanical applications

Treatment process of alumina ceramic wafer

A treatment process of alumina ceramic wafers comprises the following steps of (1) washing with distilled water: washing ceramic wafers with 100% pure water, and drying; (2) washing with acetone: soaking the washed ceramic wafers in 70-80% acetone, and drying; (3) alkali washing: soaking the ceramic wafers washed with the acetone in 10-20% sodium carbonate solution, and drying. The treatment process of the alumina ceramic wafers has the beneficial effects of being large in hardness, excellent in wear resistance, light in weight, strong in surface adhesive force (10-20 times of that of the untreated ceramic wafers), and firm and durable after being combined with rubber through glue.
