Preparation of Large Particle Yttrium Oxide Spherical Powder with High Bulk Density AITranslate
Abstract AITranslate
Using sodium carbonate or sodium bicarbonate as precipitant,the yttrium chloride feed solution was precipitated at room temperature(5~35℃),and then yttrium oxide powder was prepared by calcination.The powder was characterized by laser particle size analyzer,scanning electron microscope and Hall flowmeter(funnel method).The effects of precipitant type,precipitant/yttrium chloride molar ratio and polymer dispersant(PVA)on the surface morphology,particle size distribution and bulk density of the formed yttrium oxide powder were studied,and the optimal process conditions were determined as follows:sodium carbonate as precipitant,Na2CO3/YCl3 molar ratio≤1.5,and PVA mass fraction of 0.001%~0.01%.The obtained Y2O3powder under the above conditions has large and narrowly distributed particle size(D50=20~100μm,(D90-D10)/(2D50)<0.5),bulk density of 1.0~1.2g/cm3,good sphericity de-gree,excellent dispersibility and fluidity.The process is simple and easy to control and industrialize,with low cost and no pollution.
