RUBIES FOR REFERENCE TEMPERATURE STANDARDS.

Abstract

The vapor-phase growth technique was further developed for the growth of sapphire and ruby single crystals. Impurity content below 3 ppm was attained. Electron-microprobe technique was improved and used to demonstrate chromium doping uniformity of plus or minus 5ppm. (Author)
