•Sol-gel synthesis of Gd3+ added SiO2-ZrO2 binary oxides.•Significant role of Gd3+ content in the tetragonal and cubic stabilization of ZrO2.•Phase stability of either tetragonal or cubic stabilization till 1100 °C.•Gd3+ additions ensured additional paramagnetic behaviour in SiO2-ZrO2 binary oxide.
The present study reports the effect of gadolinium (Gd3+) in zirconia-silica (ZrO2-SiO2) binary oxides. The pure ZrO2-SiO2 synthesized at 1100 °C was tetragonal. The addition of Gd3+ in the concentration range of 5%–10% resulted in the formation of t-ZrO2, whereas higher contents of Gd3+ led to the formation of cubic ZrO2 (c-ZrO2). The presence of Gd3+ also affected the lattice parameters of both t-ZrO2 and c-ZrO2. Magnetic studies confirmed a steady increase in the paramagnetic behaviour with increasing content of Gd3+.
