Erosive wear resistance of silicon carbide-cordierite ceramics: influence of the cordierite content [PDF]
, 2015 A cordierite/SiC composite was created in situ with reactive sintering at 1250 degrees C and 1300 degrees C. The cordierite precursor was made from commercially available spinel, alumina and quartz and was mixed with the comercial SiC powder to obtain composite materials during the sintering. It was found that cordierite particles bind efficiently with
