Abstract

Inventia de fata se refera la un procedeu pentru recristalizarea explozibililor puternici HMX si RDX. în conformitate cu inventia, explozibilul este dizolvat într-o lactona cu greutate moleculara mica, lichida (la temperatura camerei), dupa care gradul de saturatie al solutiei obtinute este modificat, fie prin reducerea temperaturii, fie prin diluare cu apa. Prin aceasta metoda se obtine, în functie de metoda de cristalizare aleasa, cristale de -HMX sau cristale de RDX cu diametrul mediu al particulelor fie de 50...1500 miu m, fie de 5...50 miu m.
