Synthesis of beryl crystals

摘要

A method for synthesizing beryl crystals from a raw material substantially that of natural beryl and at least one material of molybdates, vanadates and tungstates to form a flux is provided. The raw material and oxides are melted and a rotating beryl seed crystal is placed in contact with the rotating melt zone and drawn away from melt zone so that beryl crystal is synthesized as the seed crystal is withdrawn from the melt zone. The melt zone may be formed in a zone floating furnace with rotating axes or in a rotating crucible.
