Cte Of Alumina Ceramic

Cte is usually given in units of um m c or ppm c.

Cte of alumina ceramic.

The following values are given for a temperature around 20 c. Higher purity alumina demonstrates enhanced wear and corrosion resistance creating a continuous scale of various alumina grades compositions and performance. Alumina ceramics al o alumina or aluminium oxide al 2 o 3 is a major engineering material. Property values below are taken from literature and manufacturer sources.

Coefficient of thermal expansion. Alumina aluminium oxide al 2 o 3. It offers a combination of good mechanical properties and electrical properties leading to a wide range of applications. Maximum use temperature c.

Once fired and sintered it can only be machined using diamond grinding methods. Variations are possible among various commercial grades. Learn about product material coefficient of thermal expansion. Coefficient of thermal expansion.

Choose professional dilatometry and thermal expansion coefficient cte testing services from mse analytical services. 1 x 10 6 c. Dielectric loss tan δ 1mhz 25 c. Kyocera is the global leading manufacturer of superior precision fine ceramics advanced ceramics.

Alumina can be produced in a range of purities with additives designed to enhance properties. Alumina is one of the most cost effective and widely used material in the family of engineering ceramics. Dilatometry and thermal expansion coefficient cte testing services. Fine ceramics typically have a low coefficient of thermal expansion which indicates their expansion ratio due to changes in temperature.

Alumina also known as aluminum oxide is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications. 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. Aluminum oxide al 2 o 3 ceramic properties.
