A novel technique for the preparation of gels and powders of AI203-Si02 system by the sol-gel method (original) (raw)

This research presents a novel technique for preparing aluminum oxide-silica (AI203-SiO2) gels and powders using the sol-gel method with aluminum formate as a precursor. The study explores the synthesis of homogeneous gels without the use of inorganic acids, highlighting the successful formation of multi-component silicate systems with improved solubility properties compared to traditional precursors. Key findings include the absence of residual formic acid in the final product and the effective conversion of the system into pure oxides upon calcination at elevated temperatures.
