Service description
SPS technique uses an electrical current to activate sintering processes. It combines simultaneously the application of pressure and electric current on the sample. Joule heating provides high heating rates, allowing dense ceramics to be obtained under uniform heating. The operation of a SPS unit consists of a uniaxial pressure device, in which the punches also serve as electrodes, an evacuated reaction chamber, a pulsed direct current (dc) generator and pressure-, position- and temperature regulating systems. In an SPS experiment, the powder is introduced in a die, which may be built up with various materials, such as graphite,etc. The major interest in this process, is linked to the extreme rapidity of the thermal treatment. Thus, the consolidation time is greatly decreased from hours, in the case of the conventional sintering, to few minutes for the SPS process. Moreover, the sintering temperature can be diminished by a few hundred degrees compared to conventional sintering.
