METHOD FOR RUBIDIUM-BISMUTH MOLYBDATE MONOCRYSTAL GROWING Russian patent published in 2015 - IPC C30B9/04 C30B9/12 C30B15/02 C30B15/36 C30B29/32

Abstract RU 2542313 C2

FIELD: chemistry.

SUBSTANCE: invention refers to chemical technology and concerns manufacturing crystals of rubidium-bismuth molybdate RbBi(MoO₄)₂. The crystals RbBi(MoO₄)₂ are grown from a high-temperature solution in melted charge containing rubidium dimolybdate and triple lithium-rubidium-bismuth molybdate LiRbBi₂(MoO₄)₄, in ratio of the latter toribidium dimolybdate equal to 10-40: 90-60 mole %, respectively; fuse crystallisation is focused in the direction [001], with a fuse rotation at 30-65 rpm and pulling rate 0.3-1.0 mm/day with cooling the melted solution at 0.2-1.0 degrees/day; the growing process in performed in the environment of low gradient ΔT less than 1 degrees/cm in the melted solution.

EFFECT: invention enables producing the coarse crystals RbBi(MoO₄)₂ of high optical quality.
