Spark Plasma Sintering (SPS)

Spark plasma sintering furnace

Spark Plasma Sintering (SPS) furnace is used to rapidly consolidate parts using a SPS 10-3 furnace from Thermal Technology (Santa Rosa, CA). SPS applies a pulsed direct current through a conductive graphite die assembly while simultaneously applying pressure. The die is heated through joule heating and conduction. By ultilizing joule heating, rapid heating rates (<600°C/min) can be obtained reaching temperatures >1500°C in minutes. SPS 10-3 capabilities are listed below. 

Maximum Current 3,000 amps
