| Abstract: | 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. |
