1st Paragraph: Spark plasma sintering (SPS) has become one of the primary sintering methods under investigation within the past thirty years. The most commonly reported advantage of this method is the accessibility of high heating rates, on the order of hundreds to thousands of °C per minute. However, the addition of the applied current and voltage increases the complexity of the SPS process relative to conventional pressure-assisted sintering. Although the achievement of outstanding properties using SPS is still frequently reported , most success is achieved through a trial and error approach, repeating until a good set of conditions is found .
