He tino pai te ātete o te waro hiko (SiC) ki te kakahu me te waikura nā ōna āhuatanga ā-tinana me ā-matū ahurei.
Mō te ātete ki te kakahu, ka eke te pakeke Mohs o te silicon carbide ki te 9.5, koia anake te tuarua ki te taimana me te boron nitride. Ko tōna ātete kakahu he rite ki te 266 ngā wā o te maitai manganese me te 1741 ngā wā o te rino maka chromium teitei.
Mō te ātete ki te waikura, he tino teitei te pumau matū o te silicon carbide, ā, he tino pai te ātete ki ngā waikawa kaha, ngā kawakore, me ngā otinga tote. I taua wā, he nui hoki te ātete ki te waikura o te silicon carbide ki ngā konganuku rewa pērā i te konumohe me te konutea, ā, he mea noa te whakamahi i roto i ngā oko whakarewa me ngā pokepokea ai i roto i te umanga whakarewa.
I tēnei wā, ko te waro silicon carbide me te hanganga tino mārō me tōna koretake matū kua whakamahia whānuitia i roto i ngā ahumahi pēnei i te keri, te maitai, me te matū, ā, kua noho hei rauemi tino pai i raro i ngā āhuatanga mahi tino uaua.
| rauemi | ātete kakahu | ātete ki te waikura | mahi pāmahana teitei | Ōhanga (wā roa) |
| Karāhe silicon | Tino teitei | Tino kaha | Tino pai (<1600℃) | Teitei |
| Ngā uku arumina | Teitei | Kaha | Toharite（<1200℃） | Waenga |
| Koranu whakarewa | Waenga | Ngoikore (me paninga) | Ngoikore (ngāwari ki te waikura) | ngoikore |
Poraka ātete-kākahu o te silicon carbideHe whakarōpūtanga nui te silicon carbide i roto i ngā hua silicon carbide. Nā ngā āhuatanga ātete-kakahu me te ātete-waikura o te silicon carbide ka whakamahia whānuitia i roto i ngā taputapu huri pēnei i ngā mīhini kuru maina me ngā mira pōro, ka whakaiti i te whakakapinga taputapu maha e puta mai ana i te kakahu, ā, ka whakaiti i ngā utu tiaki mīhini.
Koinei te whakataurite i waenga i ngā poraka ātete-kakahu silicon carbide me ētahi atu poraka ātete-kakahu rauemi tuku iho:
| Te Pakari me te Ātete ki te Mau | Poraka ātete-kākahu o te silicon carbide | Ngā rauemi tuku iho |
| Te Pakari me te Ātete ki te Mau | Te pakeketanga Mohs 9.5, te ātete kakahu tino kaha (ka piki ake te roa o te ora mā te 5-10 ngā wā) | He iti te pakeke o te rino maka konupora teitei (HRC 60~65), ā, he ngawari te pakarukaru o ngā uku alumina. |
| Ātete ki te waikura | Ātete ki ngā waikawa kaha me ngā kawakore | He ngāwari te waikura o ngā konganuku, engari he ātete waikawa noa iho te alumina. |
| Te pumau o te pāmahana teitei | Ātete pāmahana o te 1600 ℃, kāore e waikura i ngā pāmahana tiketike | He ngāwari te whakarewa ki te huri i te āhua i ngā pāmahana tiketike, ko te alumina ia he ātete pāmahana 1200 ℃ anake. |
| Te kawe wera | 120 W/m · K, tere te marara o te wera, ātete ki te ru wera | He pai te kawe wera o te konganuku engari he ngāwari ki te waikura, engari he ngoikore te kawe wera o ngā uku noa. |
| Ōhanga | He roa te ora, he iti hoki te utu whānui | Me whakakapi pinepine ngā konganuku, he pakarukaru ngā uku, ā, he nui ngā utu mō te wā roa. |
