I-silicon nitride edityanisiweyo yentsika ye-silicon carbide

I-silicon nitride ebotshelelwe kwi-silicon carbide

I-Si3N4 edibeneyo ye-SiC ye-ceramic refractory material, ixutywe kunye ne-SIC ephezulu ecocekileyo yomgubo kunye ne-Silicon powder, emva kwekhosi ye-slip casting, i-reaction sintered phantsi kwe-1400 ~ 1500 ° C. Ngexesha le-sintering, ukugcwalisa i-Nitrogen ecocekileyo ephezulu kwiziko, emva koko i-silicon iya kusabela nge-Nitrogen kwaye ivelise i-Si3N4, ngoko ke i-Si3N4 i-Si3N4 eboshiweyo yezinto ze-SiC yenziwe nge-silicon nitride (23%) kunye ne-silicon carbide (75%) njengeyona nto iphambili ekrwada. ,ixutywe nezinto eziphilayo, kwaye ibunjwe ngumxube, i-extrusion okanye ukugalelwa, emva koko yenziwa emva kokumiswa kunye ne-nitrogenization.

Iimpawu kunye neenzuzo:

1.Hukunyamezela ubushushu
I-2.I-conductivity ephezulu ye-thermal kunye nokuxhatshazwa kokutshatyalaliswa
I-3.Amandla aphezulu omatshini kunye nokuxhatshazwa kwe-abrasion
4.Ukusebenza kakuhle kwamandla kunye nokumelana nokugqwala

Sibonelela ngomgangatho ophezulu kunye nokuchaneka komatshini we-NSiC amacandelo e-ceramic aqhuba

1.I-Slip casting
2.Ukukhupha
3.Uni Axial Pressing
4.Isostatic Pressing
