Alumina is one of the most cost effective and widely used material in the family of engineering ceramics. Alumina ceramics al o alumina or aluminium oxide al 2 o 3 is a major engineering material. Dilatometry and thermal expansion coefficient cte testing services. Kyocera is the global leading manufacturer of superior precision fine ceramics advanced ceramics.

Aluminum oxide al 2 o 3 ceramic properties. Alumina can be produced in a range of purities with additives designed to enhance properties. 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. It offers a combination of good mechanical properties and electrical properties leading to a wide range of applications.

Variations are possible among various commercial grades. Dielectric loss tan δ 1mhz 25 c. Once fired and sintered it can only be machined using diamond grinding methods. Our dialometry testing services use netzsch dil 402 pc or similar instrument.

1 x 10 4 to 4 x 10 4. Alumina ceramics are commonly subdivided according to their alumina content ranging from 80 to more than 99. The following values are given for a temperature around 20 c. Maximum use temperature c.

Alumina alpha al2o3 99 5 categories. Cte is usually given in units of um m c or ppm c. Choose professional dilatometry and thermal expansion coefficient cte testing services from mse analytical services. Coefficient of thermal expansion.

Higher purity alumina demonstrates enhanced wear and corrosion resistance creating a continuous scale of various alumina grades compositions and performance. The coefficient of thermal expansion for a material is usually specified over a temperature range because it varies depending on the temperature. Alumina also known as aluminum oxide is a hard wearing advanced technical ceramic material frequently used in a wide variety of industrial applications.
