Dielectric Properties of High Alumina Fire Clay

Abstract

This work is concerned with the examination of the electrical properties of high ahumina content product as well as the other related properties such as porosity and mechanical properties at temperatures (20, 50, 70, 90) C. It can be concluded from this investigation that, the dielectric behavior of the high alumina product was improved with increasing the alumina content in the fire clay product which make sure to be used for dielectric purposes. Also this work showed that the fire clay end product is generally accepted as electrical insulator.This product still needs further improvement if it is to be used for industrial purpose applications.
