Aggregations noncrystalline solids

A solid polymer matrix hinders the aggregation of cryochemically prepared Ag clusters so that substantial part of Ag in the prepared Ag-PPX systems remains in noncrystalline form at ambient and even higher temperatures. As was stated in references 24, 36, and 44, all of the Ag introduced into the investigated PPX matrices transforms to nanocrystals after annealing at 373 K.
