Cte Of Alumina Ceramic

Alumina ceramics al o alumina or aluminium oxide al 2 o 3 is a major engineering material.

Cte of alumina ceramic. Alumina alpha al2o3 99 5 categories. Alumina can be produced in a range of purities with additives designed to enhance properties. Cte is usually given in units of um m c or ppm c. Coefficient of thermal expansion.

Alumina is one of the most cost effective and widely used material in the family of engineering ceramics. Aluminas are used in both general use and specialized applications. Once fired and sintered it can only be machined using diamond grinding methods. Variations are possible among various commercial grades.

Property values below are taken from literature and manufacturer sources. Fine ceramics typically have a low coefficient of thermal expansion which indicates their expansion ratio due to changes in temperature. 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.

Maximum use temperature c. Alumina oxide ceramics al2o3 is the most widely used fine ceramics material. Higher purity alumina demonstrates enhanced wear and corrosion resistance creating a continuous scale of various alumina grades compositions and performance. 1 x 10 6 c.

Kyocera is the global leading manufacturer of superior precision fine ceramics advanced ceramics. Aluminum oxide al 2 o 3 ceramic properties. 1 x 10 4 to 4 x 10 4. 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 aluminium oxide al 2 o 3. It offers a combination of good mechanical properties and electrical properties leading to a wide range of applications. Our dialometry testing services use netzsch dil 402 pc or similar instrument.

The following values are given for a temperature around 20 c. Alumina ceramics are commonly subdivided according to their alumina content ranging from 80 to more than 99. Learn about product material coefficient of thermal expansion. Dielectric strength 6 35mm ac kv mm.

Dilatometry and thermal expansion coefficient cte testing services. This material has superb material characteristics such as high electrical insulation high mechanical strength high wear and chemical resistance.
