Abstract: Quartz glass is a kind of high-purity basic material which is irreplaceable in national strategic and pillar industry and has drawn enough interests. Fused quartz glass occupied the highest production in quartz glass product industry for its extensive raw material, mature processing technique and size-controlled, etc. In this article, the effects of lattice impurities, inclusions, particle size distribution and crystal shape on fused quartz glass products were summarized in detail. Developments as well as improvements focused on electric melting method, flame fusion process, and plasma melting method in decades was induced. Above all, this work proposed the facing challenges in fused quartz glass industry and proposals for future reference.
