Cte Of Alumina Ceramic

The coefficient of thermal expansion for a material is usually specified over a temperature range because it varies depending on the temperature.

Cte of alumina ceramic.

Variations are possible among various commercial grades. 1 x 10 6 c. Learn about product material coefficient of thermal expansion. Coefficient of thermal expansion.

Dilatometry and thermal expansion coefficient cte testing services. Kyocera is the global leading manufacturer of superior precision fine ceramics advanced ceramics. Alumina also known as aluminum oxide is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications. Dielectric strength 6 35mm ac kv mm.

Property values below are taken from literature and manufacturer sources. Once fired and sintered it can only be machined using diamond grinding methods. The following values are given for a temperature around 20 c. Alumina aluminium oxide al 2 o 3.

Alumina oxide ceramics al2o3 is the most widely used fine ceramics material. Higher purity alumina demonstrates enhanced wear and corrosion resistance creating a continuous scale of various alumina grades compositions and performance. Choose professional dilatometry and thermal expansion coefficient cte testing services from mse analytical services. Fine ceramics typically have a low coefficient of thermal expansion which indicates their expansion ratio due to changes in temperature.
