| Abstract: | Ultrafine ZrO2 particles have been prepared via a new sol-gel process. This process involves the addition of excess C2H4O into the aqueous ZrOCl2 solution and reacting the mixture at room temperature; a glassy ZrO(OH)2 gel is formed moments later. An ultrafine ZrO2 powder is obtained after the gel is dried and calcined; the powder is monoclinic. The average particle size is ∼12 nm, and its specific surface area is 55.1 m2/g. In addition, partially stabilized ZrO2 can be prepared in the same manner, yielding a good result. |
