High chiyero silicon carbide akupera mkati mbiya kachulukidwe kakang'ono

(1) Mphamvu zamakina apamwamba, zabwino ngati
Mphamvu zamakina zapamwamba zimatha kuteteza kusinthika kwa zinthu, zomwe ndizofunikira kwambiri.Silicon carbide ili ndi mphamvu zamakina apamwamba kuposa corundum.Mwachitsanzo, mphamvu yopondereza ya silicon carbide ndi 224MPa, pomwe ya corundum ndi 75.7MPa yokha.Mphamvu yopindika ya silicon carbide ndi 15.5MPa, ndipo ya corundum ndi 8.72MPa.

(2) Kukana kutentha kwakukulu, coefficient yaing'ono ya kuwonjezeka kwa kutentha
Silicon carbide amapangidwa pa kutentha kwambiri.M'malo ena otentha kwambiri, zinthuzo zimafunika kuti zikhale ndi mphamvu zina zogwirira ntchito, ndikukwaniritsa kulondola kwa kukonza, ndi zoumba za silicon carbide zimatha kukwaniritsa mfundo ziwirizi.Kutentha kwambiri kwa silicon carbide ndi pafupifupi 800 ℃, ndipo kutentha kwachitsulo ndi 250 ℃ kokha.Powerengera movutikira, kuchuluka kwa kutentha kwapakati kwa SIC ndi 4.4 × 10-6/ C mumitundu ya 25 ~ 1400 ℃.Kuchulukitsa kwamafuta a SIC ndikocheperako kuposa ma abrasives ena ndi zida zotentha kwambiri.Mwachitsanzo, coefficient of thermal expansion of corundum ingakhale yokwera ngati (7~8) × 10-6/℃.

(3) Kukana dzimbiri
Silicon carbide chifukwa cha kusungunuka kwake (kutentha kwa kutentha), inertia yamankhwala ndi kukana kwamphamvu kwamphamvu, imatha kugwiritsidwa ntchito pazinthu zosiyanasiyana za silicon carbide ceramic, monga zida za ceramic zopangira ng'anjo yamoto, mbale ya denga ndi sagger, zinki zosungunula mafakitale zowongoka. ng'anjo ya cylinder distillation yokhala ndi njerwa ya silicon carbide, aluminium electrolytic cell lining, crucible, ng'anjo yaying'ono.
