摘　　要：对较有代表性的若干非金属矿物和材料比表面积、孔体积及孔径的测定条件和影响因素进行了试验研究 ,结果表明 :该方法可以测定低至 0 .1m2 的比表面积。从标准物质分析与样品外检对比可知 ,分析质量可靠 ,准确度高、重复性好、快速、简便、成本低、无污染 ,能够满足非金属矿物材料深加工和综合利用的需要。A experimental study is made on measuring conditions and affecting factors of specific surface area, pore volume and pore size of several representative non-metallic minerals and materials. The results show that this method can measure a specific surface area with lower limited of 0.1m2. By comparison with standard substance and measuring outside, the method can meet the need for further processing and comprehensive utilization of non-metallic minerals and materials with dependable quality, high accuracy, good repeatability, high-speed, convenience, low cost and non-pollution.
