I-Silicon nitride yi-ceramic engwevu enokuqina okuphezulu kokuqhekeka, ukuxhathisa ukothuka kobushushu, kunye neempawu ezingenakungeneka kwiintsimbi ezinyibilikisiweyo.
Usebenzisa ezi mpawu, isetyenziswa kumalungu enjini yokutsha yangaphakathi anje ngeendawo zenjini yemoto, imibhobho ye-welding machine welding, njl.
Ngokumelana kwayo okuphezulu kunye namandla omatshini aphezulu, izicelo zayo ekuthwaleni iinxalenye ze-roller, iibheringi ze-shaft ezijikelezayo kunye nezixhobo zokuvelisa izixhobo ze-semiconductor ezisecaleni zihlala zisanda.
