Green Manufacturing of Silicon Nitride Ceramics

Erosion resistance of engineering ceramics and comparative assessment through Wiederhorn and Evans equations

“…Schneider et al [26] demonstrated that the alignment of β-Si 3 N 4 grains can also contribute to the improvement of the wear resistance properties of the material, in some cases even surpassing that of alumina, zirconia and silicon carbide. The seek for alternatives to develop more energy efficient manufacturing techniques has been investigated by Hyuga et al [27], pointing out that the low-cost of β-phase silicon nitride, low temperature sintering, and rapid nitridation of silicon powder with zirconia addition can lead to compelling energy savings. Silicon based ceramics are also particularly interesting for scaffold prostheses due to the analogous mechanical resistance and porosity to that of bones, permitting great biocompatibility in terms of match with surrounding tissue [28].…”
