Effect of the addition of phosphotungstic acid on the thermal stability of zirconium oxide
Zirconium hydroxide [Zr(OH)4] was synthesized by the sol-gel method using zirconium n-butoxide and 1-butanol as synthesis precursors. A part of the synthesized material was impregnated with phosphotungstic acid (H3PW12O40) in order to evaluate the effect of this dopant agent on the thermal, textural...
