STUDY OF METHODS FOR IMPROVING THE QUALITY OF SYNTHETIC QUARTZ Sixth Quarterly Report 15 October 1957 to 14 January 1958

摘要

The absorption spectra of X-irradiated Z-, plus X-and minus X-growth quarts produced in the absence of added aluminum are presented.nThe spectra of X-irradiated germanium-doped minor-r synthetic quartz are compared with those of germanium-free minor-r synthetic quartz and natural quarts.nPossible causes, and a remedy, of fissure flaws in quarts grown in small autoclaves are discussed. The flaws are believed to be related to a high crystallizing temperature, and to poor diffusion of reacting species.
