Cte Of Alumina Ceramic

Our dialometry testing services use netzsch dil 402 pc or similar instrument.

Cte of alumina ceramic.

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. Learn about product material coefficient of thermal expansion. Once fired and sintered it can only be machined using diamond grinding methods. Alumina is one of the most cost effective and widely used material in the family of engineering ceramics.

Variations are possible among various commercial grades. Cte is usually given in units of um m c or ppm c. Dilatometry and thermal expansion coefficient cte testing services. Property values below are taken from literature and manufacturer sources.

Alumina ceramics are commonly subdivided according to their alumina content ranging from 80 to more than 99. Coefficient of thermal expansion. 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. 1 x 10 6 c. 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. Dielectric loss tan δ 1mhz 25 c. This material has superb material characteristics such as high electrical insulation high mechanical strength high wear and chemical resistance.
