1 x 10 4 to 4 x 10 4.
Cte of alumina ceramic.
Kyocera is the global leading manufacturer of superior precision fine ceramics advanced ceramics.
Cte is usually given in units of um m c or ppm c.
The following values are given for a temperature around 20 c.
Fine ceramics typically have a low coefficient of thermal expansion which indicates their expansion ratio due to changes in temperature.
It offers a combination of good mechanical properties and electrical properties leading to a wide range of applications.
Alumina can be produced in a range of purities with additives designed to enhance properties.
The raw materials from which this high performance technical grade ceramic is made are readily available and reasonably priced resulting in good value for the cost in fabricated alumina shapes.

Coefficient of thermal expansion.
The coefficient of thermal expansion for a material is usually specified over a temperature range because it varies depending on the temperature.
This material has superb material characteristics such as high electrical insulation high mechanical strength high wear and chemical resistance.
Alumina ceramics are commonly subdivided according to their alumina content ranging from 80 to more than 99.
Aluminas are used in both general use and specialized applications.
