摘　　要：本文就影响氧化铝及其水合物白度的诸因素中,以大量的数据侧重地展示了十年来仪器类及同种仪器台间差给测定结果带来的影响,标准白板、滤光片波长、白度公式的选择均会影响白度值,进而介绍了国际著名的甘茨(GANZ)公式。建议铝行业要建立标准并以α-Al_2O_3作为基准物质。文中大量的统计数字证明了碱石灰烧结法这一独特工艺制得的氧化铝、氢氧化铝具有理想白与喜爱白的特征。Factors regarding the whiteness determination of alumina and its hydrates, have been discussed in this paper. The influences of the testing values due to different instrument types and instruments during the past ten years were expressed particularty on a great number of data. All the different standard white boards , filter wave length and whiteness formulations selected were effect on whiteness values, and then follows the introductiom of the well-known GANT formula. A standard is surgessted to be established in aluminium industry and α1-Al2O3 may be introduced as the detum. According to mass data statistics, the productioms of alumina and aluminium hydroxide processing through sintering of alkali lime the properties of expected whiteness and pleased whiteness were obtained.
