al2o3 Alumina Ceramic washers spacers sleeves shafts

Reputation depends on quality, quality comes from Hard!


Alumina Ceramic:

The main crystalline phase is α-A12O3. The density is 3.98 g/cm3 or more. The linear transmittance is 90% to 95% or more. The dielectric constant is greater than 9.8. The dielectric loss tangent is less than 2.5×10-4 (1GC), and the flexural strength is greater than 350-380 MPa. The breakdown strength is 6.0 to 6.4 kV/mm. Thermal expansion coefficient (6.5 ~ 8.5) × 10-6 / °C. Good alkali metal vapor corrosion resistance at high temperatures.
The raw material is Al2O3 with a purity of 99.99% or more, and a small amount of additives such as pure magnesium oxide, antimony trioxide or antimony trioxide are added, and continuous isostatic pressing, atmosphere sintering or hot press sintering is performed, and the grain size is strictly controlled. Highly dense transparent ceramic.Luminous tube for the manufacture of high pressure sodium lamps (working life can exceed 20,000 h). It can also be used as a microwave integrated circuit substrate, bearing material, wear-resistant surface material and infrared optical component material.

properties:

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
