Influence of pulse current during Spark Plasma Sintering evidenced on reactive alumina–hematite powders [PDF]

, 2011
Spark Plasma Sintering (SPS) is increasingly used. The temperature and current are not independent parameters, making it difficult to separate the current intrinsic role from Joule heating.

Microstructure of Ba1−xLaxTiO3−δ ceramics sintered by spark plasma sintering [PDF]

, 2011
Nano-sized Ba1−xLaxTiO3 (0.00 ≤ x ≤ 0.14) powders were prepared by a coprecipitation method and calcined at 850 °C in air. The corresponding ceramics were obtained by Spark Plasma Sintering (SPS) at 1050 °C.
