标准摘要
[中文适用范围]: 本国际标准规定了通过单点或多点法氮吸附测定冶炼级氧化铝(SGA)比表面积(SSA)的仪器方法。 推荐使用多点法,因为可以获得更高的精度;如果使用单点法,则会得到较低的结果。 注:附录 A 解释了单点和多点确定的 BET SSA 之间的差异。 本国际标准适用于表面积在 50 m2/g 至 90 m2/g 之间的氧化铝。 [外文原描述]: ISO 8008:2005 specifies an instrumental method for the determination of specific surface area of smelter-grade alumina by nitrogen adsorption by a single- or multi-point method. A multi-point method is recommended due to the higher accuracy obtained; if a single-point method is used, a lower result will be obtained. ISO 8008:2005 is applicable to aluminas having a surface area between 50 m 2 /g and 90 m 2 /g.
英文名称Aluminium oxide primarily used for the production of aluminium — Determination of specific surface area by nitrogen adsorption
