摘要: Abstract Zirconium alkoxide which was thermally pre-treated in an inert organic solvent hydrolyzed at 250–300°C with a limited amount of water dissolved the from gas phase. This procedure afforded microcrystalline (5.8 nm) monoclinic zirconia showed high thermal stability and retained large surface areas 162 76 m2/g even after calcination 500 900°C, respectively. Thermal pre-treatment absence above 250°C essential to avoid formation tetragonal form.
