Depositing monocrystalline gallium arsenide on substrate - by vapour phase epitaxy at below atmospheric pressure

Abstract

Abstract Materials to be subjected to a glass melting process are preheated by gently moving the material and exposing it during movement to a hot gas flow derived from the melting and of a glass-making furnace and flowing at a low speed. Used for preheating glass-making ingredients. The materials, including cullet, can be preheated in a loose state, without briquetting them and without causing segregation.
