新型高性能稀土催化剂和荧光粉为了提高催化反应活性和发光效率,都要求氧化钇粉末有大的表面积。氧化钇粉末单位质量的表面积随粉末颗粒尺寸的降低而增加。
New high-performance rare earth catalyst and phosphor In order to improve the catalytic activity and luminous efficiency, require yttria powder has a large surface area. The mass per unit surface area of the yttrium oxide powder increases as the powder particle size decreases.
