| Abstract: | A new complex inorganic ion exchanger-titaniumpyrophosp- hate-ammonium molybdophosphate is synthesized.This material is investigated by thermoanalytical,electron microscopic,X-ray diffraction and chemical analysis methods.Chemical composition,structure and some related proper- ties of this ion exchanger are reported.At the same time,complex mecharics is studied by infrared spetrometry,and it is found that complex strength is due to producing a new chemical bond.As was known earlier,in parallel with this ebemical bond van der Waals forces are acting on the interface (between the new chemical bond layers) of crystallites of pure inorganic ion exchangers. |
