Spark Plasma Sintering Furnace can be used for sintering, sinter-bonding, surface treatment, and synthesis. The sample material can be metals, ceramics, nanostructured material, and amorphous material. This system perfectly fits solid electrolyte and electric thermal material research.
With this new sintering technique the tool and the component are directly heated by DC current pulses to reduce cycle times to a few minutes. The use of DC current pulses causes an additional increase in sintering activity in various materials due to the processes that occur at the points of contact of the powder particles (Joule heating, generation of plasma, electromigration, etc.). Therefore, a significantly lower temperature, as well as significantly lower mold pressure, is needed than is used for conventional hot pressing and sintering.
Additionally, the furnaces can be equipped with a radial, inductive heating system to prevent radial temperature gradients with large-sized components or to facilitate the inductive heating of materials that are otherwise inadequately conductive at room temperature. Technology like this offers entirely new possibilities to manufacture numerous materials with extraordinary characteristics, e.g.:
Sintered nanomaterial without significant grain growth
FGM («Functionally Graded Materials»)
Innovative carbide metals
Aluminum and copper alloys as well as intermetallic compounds
Structural and functional ceramics
