Silicon Carbide (sic) amawonetsa bwino kwambiri komanso kukana kwakukulu chifukwa cha kuwonongeka kwa thupi ndi mankhwala.
Pakuvala kuvala kukana, ma mohs kuuma kwa silicon carbide amatha kufikira 9.5, lachiwiri kokha kwa diamondi ndi boron nitride. Kuthekera kwake kukana ndi zofanana ndi nthawi 266 za zitsulo za manganese ndi nthawi 1741 zomwe za Christomiam zimaponya chitsulo.
Pankhani yotsutsana ndi kuchulukana, sicric korbide ali ndi mankhwala okhazikika kwambiri komanso mawonedwe abwino kukana kukana ma asidi olimba, alkali, komanso mayankho amchere. Pakadali pano, Sicon Carbide alinso kukana kwambiri kukhazikika pazitsulo zosungunula monga aluminiyamu ndi zinc, ndipo nthawi zambiri amagwiritsidwa ntchito pamiyala pazitsulo zokha.
Pakadali pano, sickon carbide yophatikizidwa ndi mawonekedwe apamwamba ndipo mawonekedwe ake amagwiritsidwa ntchito kwambiri m'makampani monga migodi, chitsulo, ndi mankhwala, ndikusankha bwino.
| malaya | kuvala kukana | Kutsutsa | Kutentha Kwambiri | Chuma chazachuma |
| Silicon Carbide | Wammwambamwamba kwambiri | Wamphamvu kwambiri | Chabwino (<1600 ℃) | M'mwamba |
| Alumina ceramics | M'mwamba | Wamphamvu | Pafupifupi (<1200 ℃) | Wapakati |
| Zitsulo zachitsulo | Wapakati | Zofooka (Zofunikira Kuphimba) | Ofooka (okonda oxidation) | Opanda mphamvu |
Silicon Carbidet KuvalaNdilo kagulu kofunikira mu silicon carbide.
Otsatirawa ndi kufananiza pakati pa Silicon Carbide Wopanda Maboda ndi Makhalidwe Abwino Kwambiri:
| Kuuma ndi kuvala kukana | Silicon Carbidet Kuvala | Zinthu Zachikhalidwe |
| Kuuma ndi kuvala kukana | Kulimbana kwa Mohs 9.5, kuvala kolimba kwambiri (moyo wowonjezeka ndi 5-10 kasanu) | Chromium yokwera kwambiri ya chitsulo chimakhala ndi mahatchi otsika (HRC 60 ~ 65), ndipo alumina Centramics amayenda bwino |
| Kutsutsa | Kugonjetsedwa ndi acid olimba ndi alkalis | Zitsulo zimakonda kuwononga, pomwe alumina ali ndi vuto lalikulu la asidi |
| Kutentha Kwambiri | Kukana kutentha kwa 1600 ℃, osasinthasintha kutentha kwambiri | Chitsulo chimakonda kusokoneza kutentha kwambiri, pomwe alumina ali ndi kutentha kwa kutentha kwa 1200 ℃ |
| Mafuta Omwe Amachita | 120 w / mu · K, kutentha kotentha, kutentha kukana | Zitsulo zimakhala ndi mawonekedwe abwino koma amakonda oxidation, pomwe malo wamba ali ndi mawonekedwe otenthetsera |
| Kagwilitsidwe kachuma | Mtengo wautali komanso wotsika kwambiri | Zitsulo zimafunikira m'malo mwake, Ceramics ndi osalimba, ndi ndalama zazitali ndizokwera |
