Determination of porosity in supports for ceramic membranes of Titanium Dioxide by gamma spectroscopy
Palavras-chave:
ceramic membranes, porosity by gamma spectroscopyResumo
Porosity in ceramic membranes supports of Titanium dioxides was investigated by gamma spectroscopy. This technique is based on the attenuation that a beam of gamma radiation suffers when crossing a material. Linear Atenuation coefficient of the material under analysis was calculated to evaluate porosity. Results showed that the porosity by the gamma-ray transmission method are higher than the values obtained by the Archimedes and geometric due to higher sensitivity of the gamma-ray transmission methodReferências
