用维布尔分布表征稀土氧化物颗粒分布张存瑞，高玮，郭咏梅，柳召刚（包钢稀土研究院包头０１４０１０）随着稀土在材料中应用的发展，对稀土氧化物不仅在纯度上提出了更严格的要求，而且对颗粒大小分布、粒子形状、比表面积也提出了要求。颗粒大小分布有以重量为基准、以... Characterization of Rare Earth Oxide Particle Size Distribution by Wiegand Distribution ZHANG Cunrui, GAO Wei, GUO Yongmei, LIU Zhaogang (Baotou Rare Earth Research Institute Baotou 014010) With the development of the application of rare earths in materials, the rare earth oxides not only have the stricter purity Requirements, but also on the particle size distribution, particle shape, specific surface area also put forward requirements. Particle size distribution based on the weight, ...
