摘要
比表面积是粉末冶金的一项重要参数,用美国康塔公司NOVA1000型气体吸附仪测定了钴粉的比表面积,研究了影响比表面积测定的因素,确定了最佳测定条件———脱附温度220℃,脱附时间2h,样品量4～7g。
The specific surface area is a important parameter in powders metallurgy. The specific surface area of cobalt powders are determined by NOVA 1000 high speed gas sorption analyzer made in Quantachrome corporation U.S.A. The affects of measuring the specific surface area are researched and the best measurement conditions are established.
