Use of Different Types of Aluminum-Containing Raw Materials in Type-E Fiber Production

Abstract

A comprehensive study was performed of various types of aluminum-containing raw materials and their effect on glass formation during smelting of borosilicate glasses for type-E fiber. It is shown that on use of non-metallurgical alumina, as compared with metallurgical alumina, disthene-sillimanite concentrate, and kaolin, a savings of energy resources for glass formation processes from 2.64 to 16.30% obtains.
