CESIUM- AND LITHIUM-CONTAINING ALUMINIUM PHOSPHATE WITH COMMON FORMULA CsLiAl(PO) AND HAVING STRUCTURE OF POLLUCITE AND METHOD FOR ITS PRODUCTION Russian patent published in 1998 - IPC

Abstract RU 2104933 C1

FIELD: synthesis of novel chemical compounds which may be used for production of active part of radionuclide sources, particularly, for production of sources of ionized irradiation of the base of cesium-137. SUBSTANCE: solution comprising stoichiometric amounts of cesium nitrate, lithium nitrate, aluminium nitrate and orthophosphoric acid is evaporated till dry residue is obtained. Residue is calcined at 650-700 C and is roasted at 1000-1050 C. Aluminium phosphate has common formula Cs₂LiAl₂(PO₄)₃ and cubic lattice, parameter of the lattice being 13.67+0.01 . EFFECT: improved quality of desired product. 3 cl, 2 tbl
