Abstract

PARTICULAS AZIDA DE METAL ALCALINO, LA MAYORIA DE LAS CUALES TIENE UNA FORMA CASI ESFERICA Y UNA ESTRUCTURA ESPONJOSA Y CUYA RELACION DE DIMENSION DE PARTICULA MEDIA EN VOLUMEN EN EL TRATAMIENTO DE DISPERSION ULTRASONICO, ES DESEABLE QUE SEA 0,4 O MENOS. YA QUE LAS CARACTERISTICAS DE AUTO-DESCOMPOSICION DE LAS PARTICULAS AZIDA DE METAL ALCALINO DE ACUERDO CON ESTA INVENCION SON BASTANTE SUAVES, PUEDEN SER MANIPULADAS FACILMENTE EN CANTIDADES GRANDES Y SON UTILES COMO UN AGENTE GENERADOR DE GAS PARA UN AIR BAG DE AUTOMOVIL.
