Heat Resistance Aluminum Oxide Ceramic Tube White Color For Industry
High pure and high temperature resistance 99% Alumina ceramic tube
1. Description
Alumina’s most notable characteristics are its high hardness and dielectric constant. These characteristics make alumina ideal for customer applications subject to high wear and/or low electric loss. This includes the manufacture of sensor caps, casings and scientific crucibles. A third characteristic of alumina: high mechanical stability, makes it the right choice for many other applications.
Alumina, one of the oldest technical ceramics, remains one of the most common still in use. Alumina, thoroughly documented since the 1920's, is an industry standard to which many other ceramic materials are compared.
