Ball milled &amp;#945; - SiC (2.73 &amp;#956;m) was consolidated rapidly using spark plasma sintering at 1800, 1900, and 2000 &amp;#778;C under 90 MPa pressure and 20 min of soaking time. Relatively high densification (&gt;90% relative density) was achieved at 2000 &amp;#778;C. The densification stages were identified, and a three stage densification process was proposed. The formal densification study was performed using the model proposed by Ashby, and the dominant mechanism for densification
