He rite tonu te mahi a te karawiti silicon ki te taimana. Ehara i te mea ko te mea mama rawa atu, engari ko te mea mārō rawa atu hoki o te uku, ā, he pai rawa te kawe wera, he iti te horapa wera, ā, he tino ātete ki ngā waikawa me ngā waikura.
Mō ngā uku karāhe silicon carbide, ka noho pūmau tonu ngā āhuatanga o te rauemi tae noa ki ngā pāmahana neke atu i te 1,400°C. Ko te modulus Young teitei > 400 GPa ka whakarite i te pumau o ngā āhuatanga. Nā ēnei āhuatanga o te rauemi i whakaritea ai te karāhe silicon hei rauemi hanga. Ka taea e te karāhe silicon te whakahaere i te waikura, te pakū me te horo me te ātete ki te kakahu waku. Ka whakamahia ngā wāhanga i roto i ngā tipu matū, i ngā mira, i ngā kaiwhakawhanake me ngā extruders, hei tauira rānei.
"Kua tino tū pakari ngā momo SSiC (sicon carbide sintered) me SiSiC (silicon carbide infiltrated silicon). He tino pai tēnei mō te hanga i ngā wāhanga matatini nui."
He haumaru te karawiti silicon mō ngā paitini, ā, ka taea te whakamahi i roto i te umanga kai. Ko tētahi atu whakamahinga noa mō ngā wāhanga karawiti silicon ko te hangarau hiri hihiri e whakamahi ana i ngā peera waku me ngā hiri miihini, hei tauira i roto i ngā papu me ngā pūnaha taraiwa. Ki te whakatauritea ki ngā konganuku, ka taea e te karawiti silicon te whakarato i ngā otinga tino ohanga me te roa ake o te ora o ngā taputapu ina whakamahia me ngā pāpāho kaha, pāmahana teitei. He pai hoki ngā uku karawiti silicon mō te whakamahi i roto i ngā āhuatanga uaua i roto i te pūhiko, te hanga matū, te hangarau pūngao, te hanga pepa me te mea he wāhanga pūnaha paipa.
Ko te karawiti silicon honohono tauhohenga, e mōhiotia ana ko te karawiti silicon kua whakakīia ki te silicon, ko te SiSiC rānei, he momo karawiti silicon e hangaia ana mā te tauhohenga matū i waenga i te waro pūngoi, te karāpeti rānei me te silicon rewa. Nā te toenga o te silicon, ka kiia te karawiti silicon honohono tauhohenga ko te karawiti silicon kua whakakīia ki te silicon, ko tōna whakarāpopototanga SiSiC rānei.
Mena ka puta te karawiti silicon parakore mā te whakapūtanga o te paura karawiti silicon, he maha ngā matū kei roto e kiia nei ko ngā āwhina whakapūtanga, e tāpirihia ana hei tautoko i te tukanga whakapūtanga mā te tuku i ngā pāmahana whakapūtanga kia iti ake. E kiia ana tēnei momo karawiti silicon ko te karawiti silicon whakapūtanga, e whakarāpopototia ana rānei ki te SSiC.
Ka riro mai te paura silicon carbide mai i te silicon carbide i hangaia e ai ki te whakaahuatanga i roto i te tuhinga silicon carbide.
