Silicon carbide zvidhinha zvine thermal conductivity inosvika 120–170 W/(m·K), ukoshi hunodarika izvo zvezvinhu zvakawanda zvesimbi nezvisiri{2}}simbi. Iyi yakakwirira yekupisa conductivity inonyanya kuverengerwa kune yakasarudzika crystal chimiro chesilicon carbide, iyo inofambisa kukurumidza kupisa kupararira kuburikidza nekristaro lattice.
Mhedziso yeThermal Conductivity muSilicon Carbide Bricks
Sepamusoro-zvinoita zveceramic material, kudziya kwesilicon carbide zvidhinha chiratidzo chikuru chekupisa kwadzo-kugona kutamisa. Iyo yepamusoro yekupisa conductivity inoreva huwandu hukuru hwekupisa kupisa. Zvidhinha zveSilicon carbide zvinotaridza kudziya kwemaitiro epamusoro zvakanyanya kupfuura aya echinyakare refractory zvinhu uye mabrasives (senge corundum), zvichikonzera kupisa kwakanyanya-kufambiswa kwekuita munzvimbo dzepamusoro{5}}tembiricha.
Zvinhu Zvinokonzera Thermal Conductivity
- Tembiricha: Thermal conductivity yesilicon carbide zvidhinha inowedzera nekukwira kwekushisa. Nepo zvinhu zvacho zvichiratidza kushambidzika kwekupisa kwepakamuri tembiricha, kuita kwayo kunotonyanya kushamisa munzvimbo dzepamusoro-dzekupisa.
- Crystal Structure: Silicon carbide crystals inoumbwa nekabhoni nesilicon maatomu akarongwa mune imwe-dimensional cubic lattice yakasiyana. Ichi chimiro chinoratidza kurongeka kwakanyanya kweatomu, iyo inowedzera kushanda kwekupisa. Pamusoro pezvo, sililicon carbide iripo mumhando mbiri dzecrystalline- -SiC uye -SiC{{5}ne-SiC ichiratidza kudziya kwepamusoro kupfuura -SiC.
- Crystal Purity: Yakakwira-purity silicon carbide zvidhinha zvinoratidza kudziya kwepamusoro. Kuvapo kwetsvina kunoshandura chimiro chemagetsi mukati mesilicon carbide makristasi, nekudaro kuderedza kupisa kwemafuta. Nekuda kweizvozvo, kuwedzera kuchena kwezvidhinha panguva yekugadzira kwakakosha pakugadzirisa kwavo kupisa conductivity.
- Heat Conduction Pathways: Kupisa kwekushisa mukati mesilicon carbide zvidhinha kunoitika zvakanyanya kuburikidza nelattice conduction uye yemagetsi conduction. Lattice conduction inoita basa guru, ine phonon vibration inoshanda seyakanyanya nzira yekupisa kupisa.
Nzvimbo dzekushandisa
Nekuda kwehunhu hwazvo hwakanaka-kusanganisira kufambiswa kwemafuta, kuderera kwekuwedzera kwemafuta, uye kusimba kwemafuta{1}}silicon carbide zvidhinha zvinoshandiswa zvakanyanya munzvimbo dzakaita seyepamusoro-magetsi emagetsi, optoelectronics, indasitiri yemakemikari, uye tekinoroji yeinjini yeroketi. Semuyenzaniso, mundima yemagetsi-ekupisa kwepamusoro, zvidhinha zvesilicon carbide zvinoshanda semidziyo yekubvisa kupisa pamidziyo yemagetsi, ichiona kushanda kwayo kwakanaka munzvimbo-zvinopisa; mumaoptoelectronics, anoshandiswa sezvishandiso zvekutarisira kupisa kwemafuta-malaser emagetsi, nokudaro zvichisimudzira kushanda zvakanaka uye kuwedzera hupenyu hwesevhisi.
