METHOD OF PREPARING MONOCRYSTALS OF POTASSIUM TITANYL ARSENATE KTiOAsO Russian patent published in 1999 - IPC

Abstract RU 2128734 C1

FIELD: crystal growing. SUBSTANCE: when preparing potassium titanyl arsenate monocrystals useful in laser technology as laser emission frequency converter, as inoculate for cooled solution-melt from intrinsic arsenate fluxes in K₂O-TiO₂-As₂O₅ system, melt with molar ratio of solvent components K₂O:As₂O₅ from 0.8:1 to 2.2:1 supplemented with 1 to 10 mol % alkali-earth metal oxide (Mg, Ca, Sr or Ba oxide) is used and crystal is grown by cooling solution and simultaneously pulling inoculate oriented in direction [100] or [010] or normally to crystal plane [011]. EFFECT: enabled preparation of defect-free monocrystals 30x40x40 cu.mm in size and weight up to 70 g. 4 ex
