ABSTRACT:
A process for synthesizing single crystalline beryl out of a molten salt is disclosed. The process comprises the steps of providing at least one flux to which is added the component oxides of beryl and optionally a colorant. The mixture thus obtained is heated at a temperature higher than the melting point of the flux to thereby form a molten salt. After the formation of the molten salt, the salt is cooled below the temperature sphere of beryl formation and is thereafter reheatd and again melted. At this point beryl crystals are added to the molten salt which thereby form single crystalline beryl from the molten salt. By the use of the process of the present invention, superior quality single crystalline beryl is produced economically and at a high yield rate.
