【摘要】 叙述了重量法BET装置的建立和比表面积的测定和"干燥器水法"测定干燥剂氧化铝的比表面积以及经典的氮吸附BET装置——ZXF-06型自动吸附仪,因为"干燥器水法"一次测定样品数量多,能满足生产的需要,这个方法从建立起一直应用至今,其测定的数据是精确的。总结了温州精晶氧化铝有限公司比表面积测定的进展。更多还原

【Abstract】 Establishment of weighting method BET apparatus,determination of specific asurface area,determination of specific surface area of desiccent aluminium oxide with ’desiccator water method’,and classical nitrogen adsorption BET device that is known as ZXF-06 automatic adsorption instrument were introduced.Because ’desiccator water method’ determines quantity so much,it has been used from its establishment right up to now,and its determination data was accurate.Progress in specific asurface area determination of Whenzhou Jingjing Alumina Co.,Ltd.was also summarized.更多还原
