Ko te Silicon carbide he momo carbide waihanga me te ngota ngota SiC.I te wa e whakakahangia ana, ka hangahia te silica me te waro i te pāmahana teitei i runga ake i te 2000°C.Ko te carbide silicone he 3.18g/cm3 te kiato ariā, he Mohs pakeke e whai ana i te taimana, me te microhardness o 3300kg/mm3 i waenga i te 9.2 me te 9.8.Na te kaha o te pakeke me te kaha o te kakahu, kei a ia nga ahuatanga o te wera nui o te wera me te whakamahia mo nga momo momo miihini-aukati, te waikura me nga waahanga miihini teitei.He momo hou o te hangarau karaera kakahu-atete.
1, āhuatanga matū.
(1) Atete oxidation: I te wa e wera ana te rauemi carbide silicon ki te 1300 ° C i roto i te rangi, ka timata te paparanga whakamarumaru o te silicon dioxide ki runga i te mata o tana karaihe carbide silicon.Na te matotoru o te paparanga whakamarumaru, kei te haere tonu te oxidize o te carbide silicon o roto, kia pai ai te aukati oxidation o te carbide silicon.Ka eke te pāmahana ki runga ake i te 1900K(1627 ° C), ka tiimata te pakaru o te kiriata whakamarumaru hauhauora, ka kaha ake te whakamaaramatanga o te carbide silicon, na ko te 1900K te pāmahana mahi o te silicon carbide i roto i te hau whakapouri.
(2) Atete waikawa me te kawakore: na te mahi o te kiriata whakamarumaru hauhaurua, he taonga a te carbide silicon i roto i te mahi o te kiriata whakamarumaru haurua.
2、Ko nga ahuatanga o te tinana me te miihini.
(1) Kiato: He tino tata te kiato matūriki o nga momo tioata carbide silicon, e kiia ana ko te 3.20g/mm3, a, ko te 1.2-1.6g/mm3 te kiato putunga taiao o te kirikiri carbide abrasives, i runga i te rahi o te matūriki, hanganga rahi matūriki me te hanga rahi matūriki.
(2) Maamaa: Ko te Mohs pakeke o te silicon carbide he 9.2, ko te micro-density o Wessler ko 3000-3300kg / mm2, ko te pakeke o Knopp he 2670-2815kg / mm, he teitei ake te abrasive i te corundum, tata ki te taimana, cubic boron nitride me te boron carbide.
(3) Waariki te kawe: ko nga hua carbide silicon he nui te kawe waiariki, he iti te whakareatanga whakareatanga waiariki, he nui te parenga waiariki, he taonga whakaahuru-kounga teitei.
