Shirye-shirye da kaddarorin siliki carbide yumbura ta hanyar amsawa sintering

Silicon carbide (SiC) wani fili ne mai hade da carbon da silicon kuma an san shi da kyawawan kaddarorin sa, gami da juriya mai girma, juriya na zafin zafi, juriya mai ƙarfi da haɓakar thermal. Waɗannan kaddarorin sun sa silicon carbide ya zama kyakkyawan abu don aikace-aikace iri-iri a cikin masana'antu da yawa, gami da sararin samaniya, masana'antar injin, petrochemicals, narkewar ƙarfe da lantarki.
