METHOD OF PRODUCING LUMINESCENT POWDER OF TERBIUM POLYTANTALATE Russian patent published in 2011 - IPC C09K11/78 C01G35/00 C01F17/00 

Abstract RU 2418836 C1

FIELD: chemistry.

SUBSTANCE: method involves mixing a tantalum compound with aqueous solution of a terbium salt in stoichiometric ratio which satisfies the composition of terbium tantalate, and thermal treatment of the obtained suspension. The tantalum compound used is tantalum hydroxide, and the terbium salt solution used is terbium acetate solution. The product undergoes thermal treatment at 850-900°C for 8-10 hours.

EFFECT: low synthesis temperature and duration of the process.
