초록
In this study a gel combustion method was used to prepare alumina nano powder. Aluminum nitrate, citric acid and glycine and urea fuels were used. An analysis of the effect of the type of fuels and their synthesis was done and followed by calcination at temperatures of 400-700-1000 ο C. The results showed that using urea as the fuel to raw material ratio of 1 to 1 and in the fuels synthesis, citric acid to urea (50% + 50%) ratio of 1 to 1 and a calcination temperature of 700 ο C, the powerful optimum conditions for the synthesis of aluminum oxide nano powder Al2O3 at dimensions of 20 nm was obtained.
