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.

X-ray diffraction patterns showed the formation of sodium carbonate and silicates in the activated samples, whereas thermogravimetric curves revealed a strong reduction in the ash content of these samples after washing with water.

Whether supplying the tools to create better semiconductor chips, enabling drug discovery, improving production line quality, or exploring the new frontier of nanotechnology, Rigaku products and services lead with innovation. This work consists in a study about the chemical diifratometria of charred rice hulls using NaOH as the activation agent.
