SPECIFICATION FOR ESP CERAMIC MATERIAL
The 51A body is a high quality aluminum oxide porcelain (alumina-silicate material) generally conforming to C610 – IEC 60672-3. The material is specially developed for high performance in demanding operating environments. It is excellent for continuous use at very high temperatures in DC applications due to its high volume resistivity.
Material data is obtained and presented in accordance with IEC standards. The numerical values determined according to these tests only apply to the prescribed specimens. These cannot be extended to specimens and ceramic products of other shapes and sizes or of another type of manufacture.
