| 摘 要： | 坡缕石（Ｐ）是一种含水镁铝硅酸盐矿物，具有层链状的晶体结构。本文采用气体吸附法测定了安徽嘉山地区坡缕石的比表面积，结果证明，坡缕石具有较大的比表面积，其数值在１３０ｍ~２／ｇ左右，为凹凸棒粘土的开发应用研究提供了十分有用的参数。

| Abstract: | Palygorskite is a magnesium-aluminum hydrosilicate displaying layer-chain-like crystal structure. Gas adsorptive method has been employed to determine the specific surface area of the palygorskite from the Jiashan area of Anhui Province. The result shows that the palygorskite has a relatively large specific surface area around 13m~2/g. This parameter is very valuable for the development and application study of the polygorskite. |
