ISO 8008:2005规定了通过单点或多点法氮气吸附测定冶炼级氧化铝比表面积的仪器方法。由于获得的精度更高,建议使用多点方法;如果使用单点法,将获得较低的结果。
ISO 8008:2005适用于表面积在50m2/g和90m2/g之间的氧化铝。
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 m2/g and 90 m2/g.
