Effect of Ball Milling on the Properties of Zirconia Powder Prepared by Alcohol-aqueous Coprecipitation Method
Zirconia precursor was prepared by an alcohol-aqueous coprecipitation process from raw materials of ZrOC12·8H2O and ammonia,the zirconia powders were subsequently obtained by calcination of the precursor at 600℃ and ball milling.The properties ofzirconia powder prepared by alcohol-aqueous method after ball-milling had been researched by BET,XRD,TEM and laser granularity instrument.The results show that by using ball-milling the agglomerate size can be effectively decreased but the primary particle size is hardly affected.The surface area of powder after calcinated can be markedly increased and narrowed size distribution can be gained by ball-milling,but the phase structure of the powder had not been changed.
