ZINC OXIDE CRYSTALS GROWING METHOD Russian patent published in 2012 - IPC C30B7/10 C30B29/16

Abstract RU 2460830 C2

FIELD: metallurgy.

SUBSTANCE: briquetted charge of chemical agent of zinc oxide, which is annealed at temperature of 1100°C during 20 hours, is used; the above charge is subject to hydro thermal re-crystallisation from potassium hydroxide solution with addition of lithium ions in tight vessels from corrosion resistant material to seeding plates oriented parallel to hemihedral edges (0001) and cut from pre-grown hydrothermal crystals of zinc oxide.

EFFECT: obtaining high-quality zinc oxide crystals on a commercial scale.
