High Temperature Thin 96% Alumina Al2O3 Ceramic Sheet

Main chacteristics of Alumina Ceramic sheet:

1. Good thermal shock resistance, greater than 220 T(℃) under rapid raising temperature and cooling

2. High thermal conductivity of 96% alumina, up to 24 W/m.k at 25℃, It's fit for heat insulation application
3. Good surface roughness, even if flatness of large size ceramic sheet to be 0.05mm after precision grinding
4. High dielectric strength, low dielectric constant and dielectric loss. It's an ideal material for insulation fileds.                     
5. Laser cutting or precision machining cutting makes tight tolerance.

The description of alumina ceramic sheets

We have been making alumina (Aluminum oxide, Al2O3) ceramic sheets for over 15 years under rigorous quality control with carefully selected high purity ceramic materials ranging from 95% to 99.8%.
All these alumina sheets offer extraordinary properties of electrical insulation, thermal conductivity, breaking strength and high-temperature resistance.  Furthermore, one of the unique properties is its superb surface roughness to be Ra0.2 which result in excellent adhesion strength with a thin film and thick film metallization due to fine particles, also it can play a very important role in sintering process which work as alumina ceramic setter.
The regular forming methods we use include tape-casting, isostatic pressing, dry pressing. We are dealing with a variety of selection of thickness from small-size to large-size capability. With our comprehensive types of manufacturing equipments, we have capability from prototyping to mass production in a short term.
