摘要
采用美国布鲁克海文仪器公司制造的90Plus粒度仪测定超细稀土氧化物粉体粒度。以氧化钇为研究对象,研究了分散剂、悬浮介质、待测样品浓度、分散时间等因素对亚微米级氧化钇粉体粒度测量精度的影响。由此确定了能准确测定亚微米级氧化钇粉体粒度的测量条件。
Yttrium oxide powders with submicron particle size prepared by precipitation method in which ammonium bicarbonate was used as precipitateforming agent were measured in 90 Plus particle size analyzer. Effects of several factors, such as the content of yttrium oxide, the selection of dispersing agent and the time of dispersion on test result were investigated. Optimum conditions of measurement were found.
