Cte Of Alumina Ceramic

Alumina can be produced in a range of purities with additives designed to enhance properties.

Cte of alumina ceramic.

Alumina also known as aluminum oxide is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications. Higher purity alumina demonstrates enhanced wear and corrosion resistance creating a continuous scale of various alumina grades compositions and performance. Once fired and sintered it can only be machined using diamond grinding methods. Our dialometry testing services use netzsch dil 402 pc or similar instrument.

Learn about product material coefficient of thermal expansion. Variations are possible among various commercial grades. Fine ceramics typically have a low coefficient of thermal expansion which indicates their expansion ratio due to changes in temperature. The following values are given for a temperature around 20 c.

Coefficient of thermal expansion. Alumina aluminium oxide al 2 o 3. Alumina is one of the most cost effective and widely used material in the family of engineering ceramics. Choose professional dilatometry and thermal expansion coefficient cte testing services from mse analytical services.

Aluminas are used in both general use and specialized applications. Kyocera is the global leading manufacturer of superior precision fine ceramics advanced ceramics. Coefficient of thermal expansion. 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.

Volume resistivity 25 c ω cm 10 14. The coefficient of thermal expansion for a material is usually specified over a temperature range because it varies depending on the temperature. Alumina oxide ceramics al2o3 is the most widely used fine ceramics material. Alumina ceramics are commonly subdivided according to their alumina content ranging from 80 to more than 99.

Dielectric strength 6 35mm ac kv mm. Maximum use temperature c. Alumina alpha al2o3 99 5 categories. It offers a combination of good mechanical properties and electrical properties leading to a wide range of applications.

Aluminum oxide al 2 o 3 ceramic properties. Alumina ceramics al o alumina or aluminium oxide al 2 o 3 is a major engineering material. 1 x 10 4 to 4 x 10 4. Dilatometry and thermal expansion coefficient cte testing services.

Cte is usually given in units of um m c or ppm c. Property values below are taken from literature and manufacturer sources.
