Study of lanthanum nitrate-sodium tetrametaphosphate-water system

Journal Article:

Abstract

The system La(NO/sub 3/)/sub 3/-Na/sub 4/P/sub 4/O/sub 12/-H/sub 2/O has been studied using the solubility method, pH- and conductometry. Found are subsequent formation of the main phases of alternate composition and neutral salt La/sub 4/(P/sub 4/O/sub 12/)/sub 3/, which is solved in Na/sub 4/P/sub 4/O/sub 12/ excess which is a result of complex formation. The soluble complexes of the composition Na/sub 5/(La(P/sub 4/O/sub 12/)/sub 2/) are obtained. The extracted complexes are investigated using the methods of paper chromatography, thermography roentgenography and IR-spectroscopy.
