Silicon Carbide, inozivikanwawo secarborundum, isilicon-carbon compound. Ichi chemikemikari chikamu chikamu cheiyo mineral moissanite. Chimiro chinongoitika cheSilicon Carbide chinopihwa zita raDr Ferdinand Henri Moissan, mufesi weFrance. Moissanite inowanzowanikwa mumaminiti mashoma mune meteorites, kimberlite, uye corundum. Aya ndiwo magadzirirwo anoitwa Silicon Carbide yakawanda. Kunyangwe zvichingoitika zvega Silicon Carbide yakaoma kuwana Panyika, yakawanda muchadenga.
Kusiyana kweSilicon Carbide
Zvigadzirwa zveSilicon Carbide zvinogadzirwa mune mafomu mana ekushandisa mune zvekutengesa engineering maapplication. Izvi zvinosanganisira
Sintered Silicon Carbide (SSiC)
Reaction Bonded Silicon Carbide (RBSiC kana SiSiC)
Nitride yakasungirirwa Silicon Carbide (NSiC)
Recrystallized Silicon Carbide (RSiC)
Mimwe misiyano yechisungo inosanganisira SIALON yakasungwa Silicon Carbide. Kune zvakare CVD Silicon Carbide (CVD-SiC), iri yakanyanyisa kuchena fomu yekomboni inogadzirwa nemakemikari vapor deposition.
Kuti sinter Silicon Carbide, zvinodikanwa kuti uwedzere sintering aids iyo inobatsira kugadzira chikamu chemvura pakupisa kwekupisa, zvichibvumira iyo Silicon Carbide zviyo kuti zvibatane.
Zvinhu zvakakosha zveSilicon Carbide
High thermal conductivity uye yakaderera coefficient yekuwedzera kwekushisa. Uku kusanganiswa kwezvivakwa kunopa yakasarudzika yekupisa kuvhundutsa kuramba, ichiita Silicon Carbide ceramics inobatsira mune dzakasiyana siyana maindasitiri. Iri zvakare semiconductor uye maitiro ayo emagetsi anoita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa. Iyo inozivikanwa zvakare nekuomarara kwayo kwakanyanya uye kusagadzikana nekuora.
Zvishandiso zveSilicon Carbide
Silicon Carbide inogona kushandiswa mune dzakasiyana siyana maindasitiri.
Kuoma kwayo kwemuviri kunoita kuti ive yakakodzera kune abrasive machining maitiro senge kugaya, honing, sandblasting, uye waterjet kucheka.
Kugona kweSilicon Carbide kumirisana nekupisa kwakanyanya pasina kutsemuka kana kukanganisa kunoshandiswa mukugadzirwa kweceramic brake discs emotokari dzemitambo. Inoshandiswawo sechinhu chezvombo mumabhuruku uye sechinhu chekuisa chisimbiso chepombi shaft zvisimbiso, apo inowanzomhanya nekumhanya kwakanyanya kusangana neSilicon Carbide chisimbiso. Silicon Carbide's high thermal conductivity, iyo inokwanisa kudzima kupisa kwemhepo kunogadzirwa nerubbing interface, mukana wakakura mune izvi maapplication.
Nekuda kwehukukutu hwepamusoro hwezvinhu, inoshandiswa mune dzakawanda zveinjiniya zvikumbiro apo mazinga akakwira ekupikisa kutsvedza, erosive uye corrosive kupfeka kunodiwa. Kazhinji, izvi zvinoshanda kune zvikamu zvinoshandiswa mumapombi kana mavharuvhu mune oirifield application, uko zvakajairwa simbi zvikamu zvinoratidzira zvakanyanya kupfeka mitengo inotungamira mukutadza nekukurumidza.
Iyo komputa ine yakasarudzika magetsi emagetsi semiconductor inoita kuti ive yakakodzera kugadzira ekupedzisira uye akakwira-voltage light-emitting diodes, MOSFETs, uye thyristors yekumusoro-simba switch.
Iyo yakaderera coefficient yekuwedzera kwekupisa, kuomarara, kuomarara, uye kupisa conductivity kunoita kuti ive yakakodzera kune enyeredzi teresikopu magirazi. Thin filament pyrometry inzira yekuona iyo inoshandisa Silicon Carbide filaments kuyera tembiricha yemagasi.
Inoshandiswawo mukudziya zvinhu zvinofanirwa kumira zvakanyanya kutonhora kwakanyanya. Inoshandiswawo kupa tsigiro yezvimiro mune yakakwirira-tembiricha gasi-yakatonhorera nuclear reactors.
