The invention relates to new chemical coordinative structure compounds, namely to amorphous double salt zinc-cadmium aquaaminoorthophosphate in solid state of general formula ZnCd(PO)·n(NH)·m(HO), where x=0.6-2.4; n=1.3-3.1; m=2.3-3.4, which can be used for the luminophor preparation. A process for the preparation of amorphous double salt zinc-cadmium aquaaminoorthophosphate, in which fixed ratio between the content of Znand Cdis achieved by solving of mechanical mixture of crystal compounds Zn(PO)·4HO and Cd(PO)·5HO, taken in mole ratio Zn:Cd from 2.4:0.6 to 0.6:2.4, in excess of concentrated water solution with a further solid compound deposition by means of phosphate ammonia solution infusion to the acetone and its holding in air at 15-25 ºС to complete hardening and constant mass. |
