Spark Plasma Sintering. Spark Plasma Sintering (SPS) Hot Press (AGUS-PECS SS-250Rx) - in SPS RF current is passed through a powder compact. The heat is generated mainly at the boundaries between powder grains, due to an increased impedance there, allowing compacting the powder without melting the grains, in contrast to the conventional hot pressing.
In this thesis, studies on the processing of cerium dioxide and its composites using a novel sintering technique called Spark Plasma Sintering (SPS) were carried out. The effect of SPS process parameters on the physical and chemical changes of cerium dioxide were investigated.

Spark Plasma Sintering. Sintering is the process of making objects from powder, by heating the material in a furnace below its melting point so that bonding takes place by diffusion of atoms. This leads to individual powder particles adhering to each other in a dense compact. The process is usually used for ceramics.
High-Temperature Ceramic Processing Laboratory. High-temperature furnaces, including a spark plasma sintering, or SPS, furnace by Thermal Technology; a high-temperature tube furnace-controlled ramp rate up to 1100 °C; a high-temperature box furnace-controlled ramp rate up to 1700 °C; and glass-melting furnaces-standard box furnace operated up
2019416Spark plasma sintering (SPS) was used to produce the nanocomposite materials. Before mixing with the Al powder, the as-received MWCNTs were ultrasonically treated in ethanol for 15 min to decrease the agglomeration. Then the suspension of the CNTs was mixed with Al powder for 7 h by a planetary ball mill at room temperature under argon atmosphere.
Spark plasma sintering (SPS) was performed under vacuum condition in an SPS furnace (SPS-1050, Sumitomo, Japan). Chinese Ceramics Communications II α-Al2O3 powders is conducted in a graphite die with an inner diameter of 25 mm on a SPS-20T-10 spark plasma sintering furnace (Shanghai Chenhua Electric Furnace Ltd.) in a vacuum level lower than 8 Pa.
The Direct Current Sintering (DCS) furnace is Thermal Technology's product offering for the process known as Spark Plasma Sintering (SPS) or the Field Assisted Sintering Technique (FAST). The process uses high electrical current to rapidly heat a conductive tooling assembly under simultaneous uniaxial pressure inside of a vacuum chamber.
