Structure changes in the sol-gel systems of hydrated oxides

Sols of hydrated aluminium oxide, hydrated zirconium oxide and their mixtures were investigated during the xerogel–amorphous‐product–crystalline‐product transition by SAXS using synchrotron radiation. In the different temperature regions certain changes in structure and morphology were observed. Som...

Summary:Sols of hydrated aluminium oxide, hydrated zirconium oxide and their mixtures were investigated during the xerogel–amorphous‐product–crystalline‐product transition by SAXS using synchrotron radiation. In the different temperature regions certain changes in structure and morphology were observed. Some correlation between the characteristics of the initial sols and their mixtures (the size and shape of the pores) was observed. In the temperature region 298–1173 K the characteristics of the mixed sol are defined by the characteristics of the initial sols.
