In this work was utilized the Polymeric Precursor method to synthesis ceramic powders of Na
+ β alumina. We were interested in determinate the initial quantity from sodium precursor and its effect on crystalline
phase obtained. Powders obtained were characterized using Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD)
and Scanning Electron Microscopy (SEM). The effect of the initial quantity of sodium in the sample was very
important in the nature of the final product. If we used one stoichiometric quantity of NaOH, to obtain NaAl11O17 compound, we obtained α-alumina as finish product (1450ºC). On the other hand, β alumina and/or Na2Al2xO3x-1 were obtained in samples thermal treatment from 1000ºC to 1350ºC. When we used a higher quantity of NaOH, sample nonstoichiometric, a solid with NaAl11O17 as majority phase was obtained.
