Cte Of Alumina Ceramic

Aluminum oxide al 2 o 3 ceramic properties.

Cte of alumina ceramic. The coefficient of thermal expansion for a material is usually specified over a temperature range because it varies depending on the temperature. Alumina alpha al2o3 99 5 categories. Alumina oxide ceramics al2o3 is the most widely used fine ceramics material. Alumina aluminium oxide al 2 o 3.

Dielectric strength 6 35mm ac kv mm. Variations are possible among various commercial grades. 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. Alumina also known as aluminum oxide is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications. Once fired and sintered it can only be machined using diamond grinding methods. 1 x 10 4 to 4 x 10 4.

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. Cte is usually given in units of um m c or ppm c. Learn about product material coefficient of thermal expansion. 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. This material has superb material characteristics such as high electrical insulation high mechanical strength high wear and chemical resistance. Aluminas are used in both general use and specialized applications. Higher purity alumina demonstrates enhanced wear and corrosion resistance creating a continuous scale of various alumina grades compositions and performance.
