| Abstract: | To meet China's urgent need,much research bas been done on preparation of ultrafine ZrOZ powderby two commonly used methods, includiDg chemical precipitation process.This paper presents further imProvement of quality of such powder through jUdicious choice of technological parameters for chemicalPrecipitation process.The properties of a ceramic material depend mainly on the nature of powder sintered.Thendcrostructurc of ceramics are determined.to a large cxten'by particle shape,size,distribution.agglomeration, etc.In this paper,our research shows a PH value of 10.0 and a solution concentration of0.smol% should be selected in order to obtain ZrO2 powder of sphericaly-shaped particles between 0.1and 0.5 pm in diameter,a Dearly uniform particle size distribution,and"soft"agglomerates. |
