摘 要: 用Q900自動圖象分析系統(tǒng)測定了用(NH4)2WS4熱分解制備的WS2顆粒的分形結(jié)構(gòu)，得到WS2周邊分維數(shù)Df在1. 015~1. 032范圍，表面分維數(shù)Ds在2.015~2.032范困，其分維數(shù)隨著粒度減小而增大。給出了Df、 Ds與顆粒等效直徑d的關(guān)系，Df、Ds可以作為WS2顆粒形狀和大小的表征值。

Abstract:Using Sb-Pb alloy containing 3%一10% Pb produced by some smelters in Guangxi as raw materials. further processing on antimony products has been studied as to develop a series of products . Cubic system ， mirco-particle, non-dusting and high percetage(99. 999%) antimony trioxide,high percentage(99.999%)antimony and several lead base engineering alloys have been developed by means of technological method;morover Sb and Pb alloy have been untilized fully and effectively.
Key words: Sb-Pb alloy with high lead content further processing comprehensive utilization
