摘要: The idea and basic embodiment of the flame-fusion process were announced by Verneuil in 1902; initially only purpose was to make gem rubies.(1,2) chief virtues this method as far today’s technology research are concerned that it can be applied a variety oxides, no crucible is required hold melt. Problems connected with use crucible, such contamination or reaction material, thereby avoided, an advantage more important higher melting point crystal.
