AB - COMMONEST INCLUSIONS IN OPTICAL VACUUM- COMPRESSED QUARTZ GLASS F. Ya. Borodai and M. I. Kharchenko UDC 666.22.666.192 Owing to its very favorable property of high transparency in the near infrared region, vacuum- compressed quartz glass is currently in wide use. The industrial process for the production of this glass since the time of its development (the start of the 20th century} has undergone considerable changes, and in recent years has been greatly improved. However, obtaining glass without visible inclusions still remains as one of the main problems in the production of quartz transparent glass. In transparent vacuum-compressed quartz glass melted from granules of rock crystal in graphite crucibles we encounter many inclusions, differing both in characteristics and in the nature of their formation. Nevertheless, the practice of melting vacuum-compressed quartz glass under production conditions shows that the most common inclusions are: smoky semitransparent; white, threadlike; smoky with a dense core~ and transparent glassy inclusions. Other inclusions are encountered much less fre- quently and only infrequently give rise to loss. The aim of this paper was to investigate the cause of the appearance of the above types of inclu- sions and to find methods of eliminating them. Smoky Semitransparent Inclusions
