Sintering of Copper Ultrafine Powders

Sintering characteristics were examined for the Oxidized (subjected to slow oxidation treatment) Cu and the Fresh (not subjected to slow oxidation treatment) Cu ultrafine powders(UFPs). Gas desorption, reduction and densification of two kinds of Cu UFPs during sintering in a vacuum or in a hydrogen atmosphere were discussed.
