METHOD OF PRODUCING BORATE α-LiCdBO Russian patent published in 2020 - IPC C30B1/02 C30B29/22 C01B35/12 G02F1/355 

FIELD: chemistry.

SUBSTANCE: invention relates to material science, particularly to production of polycrystalline borates which can be used as nonlinear optical materials. Method of producing low-temperature modification of lithium bromate and cadmium borate α-LcCdBO₃ by thermal treatment of the initial mixture Li₂CO₃, CdO and H₃BO₃ consists in the fact that the mixture additionally contains MnO at the following ratio of components, mol. %: Li₂CO₃ - 20.0; CdO - 39.6; H₃BO₃ - 40.0; MnO - 0.40, wherein the obtained mixture is heat treated at temperature of 350 °C, then 500 °C and 650 °C for 10, 40 and 50 hours respectively. Manganese oxide impurities additive is added to stabilization of hexagonal modification of LiCdBO₃ crystal structure.

EFFECT: as a result one-phase target product of double borate is obtained α-LcCdBO₃ at lower power inputs and process duration.
