I-Silicon Nitride Ceramic

Iiseramikhi zeSilicon nitride (Si3N4)

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.
