| titleOfInvention | Production of beryl single crystal |
| abstract | PURPOSE: To produce a high quality beryl single crystal having little irregularity in the color by additionally putting Cr 2 o 3 during the growth of a crystal by slow cooling with starting materials for beryl melted in a flux. n CONSTITUTION: BeO, Al 2 O 3 and SiO 2 as starting materials for beryl and Cr 2 O 3 as a colorant are put in one or more kinds of fluxes selected among vanadium pentoxide, lithium molybdate, sodium molybdate, potassium molybdate, molybdenum trioxide and lithium oxide by such amounts that saturation is attained and they are melted. A seed crystal is then put and a crystal is grown by slow cooling. during the growth, Cr 2 O 3 as a dopant is additionally put by 0.005W0.1wt% of the amount of the fluxes. By this method, a high quality beryl single crystal having little irregularily in the color is obtd. and a significant effect is produced especially when the crystal is used as a jewel. n COPYRIGHT: (C)1987,JPO&Japio |
