Spark Plasma Sintering of Two Commercial Al₂O₃ Powders

Abstract:

Al₂O₃ ceramic is prepared by spark plasma sintering (SPS) using two commercial α-Al₂O₃ powders at elevated sintering temperature. The relative density and average grain size of the prepared Al₂O₃ ceramics are measured and compared. One α-Al₂O₃ powder has good sintering property because the relative density of the prepared α-Al₂O₃ ceramic is higher than 97% while another α-Al₂O₃ powder has poor sintering property.
