Silicon Carbide (Sic) wuxuu soo bandhigayaa caabbinta aadka u adag iyo iska caabbinta sababtoo ah dhismaheeda jir ahaaneed iyo kiimikada ee gaarka ah.
Marka laga hadlayo caabbinta caabbinta, MOHS adkaanta silicon Carbide waxay gaari kartaa 9.5, labaad oo keliya oo keliya Diamond iyo Boron Nitride. Iska caabbinta jirku wuxuu u dhigantaa 266 jeer in manganese birta iyo 1741 jeer ee chromium-ka sare ee birta.
Marka laga hadlayo iska caabbinta, silicon Carbide waxay leedahay xasillooni kiimiko aad u sareysa oo muujinaya iska caabbinta heer sare ah ee aashitada adag, aashita, iyo xalka cusbada. Dhanka kale, Silicon Carbide sidoo kale wuxuu leeyahay iska caabbinta xasaasiyadeed oo ah bir bir ah sida aluminium iyo zinc, waxaana badanaa loo isticmaalaa digirta iyo wasakhaynta ee warshadaha macdanta.
Waqtigan xaadirka ah, Silicon Carbide oo ay weheliso qaab dhismeedka superhard-ka ah oo ay si weyn loo isticmaalo warshadaha sida macdanta, birta, iyo kiimikada, inay noqdaan doorasho ku habboon xaalado shaqo oo aad u fiican.
| wax | Xiro iska caabin | Iska caabista xasaasiyadda | Waxqabadka Heerkulka Sare | Dhaqaale (muddo-dheer) |
| Silicon Carbide | Aad u sarreeya | Aad u xoog badan | Aad u fiican (<1600 ℃) | Sare ah |
| Alumina dhoobada | Sare ah | Xoog leh | Celcelis ahaan (<1200 ℃) | Heer dhexe ah |
| Bir bir ah | Heer dhexe ah | Daciif (u baahan daahan) | Daciif ah (u nugul) | Daciifsan |
Xannibaadda loo yaqaan 'Silicon Carbide'waa kala soocitaan muhiim ah oo ka kooban badeecadaha silicon carbide-ka.
Waxyaabaha soo socdaa waa isbarbardhiga u dhexeeya baloogyada u adkaysta silicon carbide-ka iyo waxyaabaha kale ee dhaqanka ah ee dharka u adkeysta:
| Adag tahay iyo caabbinta caabbinta | Xannibaadda loo yaqaan 'Silicon Carbide' | Qalabka dhaqameed |
| Adag tahay iyo caabbinta caabbinta | MOHS adken 9.5, aad u xoog badan caabbinta (nolosha ayaa kordhay 5-10 jeer) | Chromium chromium cronsen birta waxay leedahay si adag (HRC 60 ~ 65), iyo alumina dhoobada ayaa u nugul dildilaaca |
| Iska caabista xasaasiyadda | U adkaysata aashitada adag iyo alkalis | Biraha waxay u nugul yihiin xarkaha, halka Alumina ay celcelis ahaan caabbinta aashito ah |
| Xasillooni sare | Iska caabbinta heerkulka ee 1600 ℃, oo aan ku jirin heerkulka sare | Birta waxay u nugul tahay inuu cilad ku muujiyo heerkulka sare, halka alumina uu leeyahay iska caabbinta kuleylka 1200 ℃ |
| Hormalka kuleylka | 120 w / m · k, kuleylka degdega ah ee kuleylka, caabbinta naxdinta leh | Birta waxay leedahay fal-gal kuleyl wanaagsan laakiin waxay u nugul tahay in lagu xumo, halka dhoobada caadiga ahi ay leedahay fal kuleyl xumo |
| Dhaqaale ah | Nolosha dheer ee nolosha iyo qiimaha guud ee hooseeya | Biraha waxay u baahan tahay beddelaad isdaba joog ah, dhoobada waa mid jilicsan, oo kharashaadka muddada-dheer ayaa sarreeya |
