Cte Of Alumina Ceramic

It offers a combination of good mechanical properties and electrical properties leading to a wide range of applications.

Cte of alumina ceramic.

1 x 10 4 to 4 x 10 4. Coefficient of thermal expansion. Variations are possible among various commercial grades. Alumina oxide ceramics al2o3 is the most widely used fine ceramics material.

Maximum use temperature c. Dielectric strength 6 35mm ac kv mm. Alumina is one of the most cost effective and widely used material in the family of engineering ceramics. 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.

Fine ceramics typically have a low coefficient of thermal expansion which indicates their expansion ratio due to changes in temperature. Our dialometry testing services use netzsch dil 402 pc or similar instrument. The coefficient of thermal expansion for a material is usually specified over a temperature range because it varies depending on the temperature. Cte is usually given in units of um m c or ppm c.

Property values below are taken from literature and manufacturer sources. Choose professional dilatometry and thermal expansion coefficient cte testing services from mse analytical services. The following values are given for a temperature around 20 c. Dilatometry and thermal expansion coefficient cte testing services.

Aluminas are used in both general use and specialized applications. This material has superb material characteristics such as high electrical insulation high mechanical strength high wear and chemical resistance. Alumina aluminium oxide al 2 o 3. Dielectric loss tan δ 1mhz 25 c.

Alumina can be produced in a range of purities with additives designed to enhance properties. Volume resistivity 25 c ω cm 10 14. Once fired and sintered it can only be machined using diamond grinding methods. Coefficient of thermal expansion.

Learn about product material coefficient of thermal expansion. Higher purity alumina demonstrates enhanced wear and corrosion resistance creating a continuous scale of various alumina grades compositions and performance. Alumina ceramics are commonly subdivided according to their alumina content ranging from 80 to more than 99. 1 x 10 6 c.
