DIFRATOMETRIA DE RAIO X PDF

Os experimentos de difratometria de raio-X revelaram a conversão do fármaco de sua forma cristalina para a forma amorfa, mais solúvel. Consequentemente. Utilizaram-se os métodos empíricos de difratometria de raios X e espectroscopia de infravermelho para as determinações dos índices de. difratografias de raios-X. Foram utilizadas as borrachas nitrílicas NBR . a dispersão das argilas, a técnica de difratometria de raios-X é utilizada em larga.
