De siste \u00e5rene har folk utf\u00f8rt mye forskning p\u00e5 sintring av lufttrykk og oppn\u00e5dd store fremskritt. Gasstrykksintring av silisiumnitridkeramikk utf\u00f8res ved en temperatur p\u00e5 ca. 2000 \u00b0C under et gasstrykk p\u00e5 1 til 10 MPa. H\u00f8yt nitrogentrykk undertrykker pyrolyse av silisiumnitrid. P\u00e5 grunn av bruken av sintring ved h\u00f8y temperatur er tilsetningen av mindre sintringshjelpemidler nok til \u00e5 fremme veksten av si3n4-keramikkorn, og oppn\u00e5 keramikk med h\u00f8y seighet med in situ vekst av lange s\u00f8ylekorn med en tetthet> 99%. Derfor kan lufttrykk sintring si3n4 keramikk brukes mer og mer i laboratorium og i produksjon. Gasstrykk sintret silisiumnitridkeramikk har h\u00f8y seighet, h\u00f8y styrke og god slitestyrke, og kan direkte produsere forskjellige komplekse former n\u00e6r den endelige formen, noe som i stor grad kan redusere produksjonskostnadene og prosesseringskostnadene for silisiumnitrid. Og produksjonsprosessen er n\u00e6r produksjonsprosessen for sementkarbid, egnet for masseproduksjon.<\/p>","protected":false},"excerpt":{"rendered":"
