I-silicon nitride eboshwe nge-silicon carbide square beam

Incazelo emfushane:

I-Si3N4 eboshiwe i-SiC njengohlobo olusha lwe-refractory material, isetshenziswa kabanzi.Izinga lokushisa elifaka isicelo lingu-1400 C.Inokuqina okungcono kwe-thermal, ukushaqeka okushisayo, okungcono kune-plain refractory material.Iphinde ibe ne-anti-i-oxidation, ukumelana nokugqwala okuphezulu, ukumelana nokugqokwa, amandla okugoba aphezulu.Ingakwazi ukumelana nokugqwala nokukhuhla, ingabibikho ukushisa okungcolile nokusheshayo ngensimbi encibilikisiwe njenge-AL,Pb,Zn,Cu ect.

描述

I-silicon nitride eboshwe nge-silicon carbide

I-Si3N4 eboshiwe ye-SiC Ceramic refractory material, ixutshwe nempushana ehlanzekile ye-SIC ephezulu kanye ne-Silicon powder, ngemva kwesifundo sokushibilika, ukusabela okufakwe ngaphansi kwe-1400 ~ 1500 ° C.Ngesikhathi se-sintering, ukugcwalisa i-Nitrogen ehlanzekile ephezulu esithandweni, khona-ke i-silicon izosabela ne-Nitrogen futhi ikhiqize i-Si3N4, Ngakho-ke i-Si3N4 eboshiwe ye-SiC impahla yenziwe nge-silicon nitride (23%) kanye ne-silicon carbide (75%) njengempahla eluhlaza. ,ixutshwe nezinto eziphilayo, futhi ibunjwe ngengxube, i-extrusion noma ukuthululwa, bese yenziwa ngemva kokumiswa kanye ne-nitrogenization.
