In this paper is presented a comparative evaluation study concerning the methods of getting some electrical contact materials on silver basis, containing 90 wt. % Ag and 10 wt. % metallic oxides, namely CdO, ZnO or SnO2. Two technological routes of powder mixtures preparation have been adopted: mechanical homogenization and chemical precipitation, respect ively. The influence of the oxide phase type upon the physical and mechanical characteristics and upon the functional behaviour of these materials included as electrical contacts in electromagnetic contactors of In = 40 A, working in air has been established. All the types of studied materials fulfilled to the normative in force concerning the functional characteristics. Some small differences were noticed regarding to the electrical erosion behaviour.
Sintered electrical contact materials, Ag-CdO, Ag-ZnO, Ag-SnO2.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
