Полученные крис- таллы сушат при 10О°С. Химический анализ осадка показывает, что его состав соответствует составу (N Н), Ag (P0,)j Пример 4, Аналогично описанным . „.. примерам. 6О мл смеси из 9 мл 2М раство- . -, ра нитрата алюмини , 4 мл 15М раствора , , ,,о со/ ортофосфорной кислоты и 25% раствора гидроокиси аммони  с рН 5.3, выдерживают „ „ , 22 ч при 1оО С в воздушном термостате, п; гДальнейшие операции те же, что и в приме э , .. „ 1 о Химический анализ осадка показывает, что его состав соответствует составу NHi Af 2 (РО/,)2 ОН 2НгО3 . 4 Сложные фосфаты алюмини  дл  рубиди  и цези  получают как описано в примерах 1 и 4, форму л а изобретени  получени  сложных фосфатов путем взаимодействи  растворов нЕ тратньк „ л. j.j. солеи с ортофосфорной кислотой и щелочью „ при нагревании и рН пульпы 2«7, о т л к „ чающийс  тем, что, с целью , , чени  ортофосфатов алюмини  и щелочного металла, в качестве нитратной соли используют нитрат алюмини  и процесс ведут при „ , . 3-10-кратном изоытке фосфорной кислоты „ /лО температуре С.(54) METHOD FOR OBTAINING COMPLEX Phosphates 52 3 aluminum nitrate, 8 ml of 15M orthophosphoric acid and 25% ammonium hydroxide solution with pH 7 are kept for 10 hours at 100 ° C in an air thermostat. The resulting crystals are dried at 10 ° C. Chemical analysis of the precipitate shows that its composition corresponds to the composition of (N H), Ag (P0,) j Example 4, as described. „.. examples. 6O ml of a mixture of 9 ml of 2M solution. -, aluminum nitrate, 4 ml of 15M solution,,, o with co / phosphoric acid and 25% ammonium hydroxide solution with pH 5.3, are kept for 22 hours at 1 ° C in an air thermostat, p; The most recent operations are the same as in example. .. 1 o The chemical analysis of the precipitate shows that its composition corresponds to the composition NHi Af 2 (PO /,) 2 OH 2HgO3. 4 Complex aluminum phosphates for rubidium and cesium are prepared as described in examples 1 and 4, the formula of the invention for producing complex phosphates by reacting solutions of less phosphate. j.j. salt with orthophosphoric acid and alkali “when heated and the pH of the pulp is 2“ 7, about one to one with the fact that, for the purpose, of the orthophosphate aluminum and alkali metal, aluminum nitrate is used as the nitrate salt and . 3-10 times phosphoric acid isoying „/ lO temperature C.
