Cte Of Alumina Ceramic

Property values below are taken from literature and manufacturer sources.

Cte of alumina ceramic.

Variations are possible among various commercial grades. 1 x 10 6 c. Higher purity alumina demonstrates enhanced wear and corrosion resistance creating a continuous scale of various alumina grades compositions and performance. 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.

Kyocera is the global leading manufacturer of superior precision fine ceramics advanced ceramics. Alumina oxide ceramics al2o3 is the most widely used fine ceramics material. Coefficient of thermal expansion. Maximum use temperature c.

The following values are given for a temperature around 20 c. Alumina ceramics al o alumina or aluminium oxide al 2 o 3 is a major engineering material. Alumina aluminium oxide al 2 o 3. Cte is usually given in units of um m c or ppm c.

Fine ceramics typically have a low coefficient of thermal expansion which indicates their expansion ratio due to changes in temperature. Volume resistivity 25 c ω cm 10 14. Alumina can be produced in a range of purities with additives designed to enhance properties. Alumina ceramics are commonly subdivided according to their alumina content ranging from 80 to more than 99.

Our dialometry testing services use netzsch dil 402 pc or similar instrument. Alumina also known as aluminum oxide is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications. Dielectric loss tan δ 1mhz 25 c. Choose professional dilatometry and thermal expansion coefficient cte testing services from mse analytical services.

1 x 10 4 to 4 x 10 4. Alumina alpha al2o3 99 5 categories. Learn about product material coefficient of thermal expansion. This material has superb material characteristics such as high electrical insulation high mechanical strength high wear and chemical resistance.

Once fired and sintered it can only be machined using diamond grinding methods. Coefficient of thermal expansion. 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.

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