Girini silicon carbide uye nhema silicon carbide: Kusiyana kwakadzama kupfuura ruvara
Mumunda mukuru wezvinhu zvemaindasitiri,kabhidhi yegirini yesiliconuyekabhidhi nhema yesilicon zvinowanzotaurwa pamwe chete. Zvese zviri zviviri zvinhu zvakakosha zvinogadzirwa nekunyungudutsa kupisa kwakanyanya muzvitofu zvine zvinhu zvakaita sejecha re quartz ne petroleum coke, asi kusiyana kwazvo kunopfuura kusiyana kwemavara ari pamusoro. Kubva pakusiyana kudiki kwezvinhu zvakagadzirwa, kusvika pakusiyana kwemaitiro ekushanda, kusvika pakusiyana kukuru kwekushandiswa, kusiyana uku kwakabatana nemabasa akasiyana evaviri ava mumunda wemaindasitiri.
1 Musiyano mukuchena kwezvinhu zvakabikwa uye chimiro chekristaro unosarudza hunhu hwakasiyana hwezvinhu zviviri izvi.
Kabhidhi yegirini yesiliconYakagadzirwa nepetroleum coke nejecha re quartz sezvinhu zvikuru, uye munyu unowedzerwa kuti uchenese. Kuburikidza nemaitiro aya, huwandu hwetsvina hunoderedzwa zvakanyanya, uye kristaro isystem yakajairika ine mipendero yakapinza nemakona. Kugadziriswa kwezvinhu zvisina kucheneswa kwe black silicon carbide kuri nyore, uye hapana munyu unowedzerwa. Tsvina yakaita sesimbi nesilicon inosara muzvinhu zvisina kucheneswa inoita kuti zvidimbu zvayo zvekristaro zvive zvisina kurongeka uye zvakatenderera uye zvisina kujeka pamipendero nemakona.
2 Kusiyana kwezvinhu zvakagadzirwa uye maumbirwo kunoita kuti pave nemarudzi akasiyana ezvimiro zvemuviri zvezviviri izvi.
Panyaya yekuomarara, kuomarara kweMohskabhidhi yegirini yesiliconine huremu hunenge 9.5, yechipiri kune dhaimani, uye inogona kugadzirisa zvinhu zvekuomarara zvakanyanya; black silicon carbide ine huremu hunenge 9.0, nekuomarara kwakaderera zvishoma. Panyaya yehuremu, green silicon carbide ine huremu hunosvika 3.20-3.25g/cm³, ine chimiro chakakora; black silicon carbide ine huremu hunosvika 3.10-3.15g/cm³, isina kusimba zvakanyanya. Panyaya yekushanda kwayo, green silicon carbide ine kuchena kwakanyanya, thermal conductivity yakanaka, electrical conductivity uye high tembiricha resistance, asi haina kusimba uye iri nyore kupatsanurwa kuita mipendero mitsva; black silicon carbide ine thermal conductivity isina kusimba uye electrical conductivity, low brittleness, uye particle impact resistance yakasimba.
3 Kusiyana kwekushanda kunoita kuti pave nepfungwa huru pamusoro pekushandiswa kwezviviri izvi.
Green silicon carbide inekuomarara kwakanyanyauye zvidimbu zvakapinza, uye inokwanisa kugadzirisa zvinhu zvine kuoma kwakanyanya uye kusimba kushoma: mumunda usiri wesimbi, inogona kushandiswa pakukuya girazi, kucheka ceramic, semiconductor silicon wafers, uye kupukuta sapphire; mukugadzira simbi, ine mashandiro akanaka ekugadzirisa zvinhu zvakaita secarbide yakagadzirwa nesimende nesimbi yakaoma, uye inoshandiswa zvakanyanya muzvigadzirwa zvakaita semavhiri ekukuya nemadisc ekucheka. Black silicon carbide inonyanya kugadzirisa zvinhu zvine kuoma kwakanyanya uye kusimba kwakanyanya uye yakakodzera kugadziriswa kwesimbi dzisina ferrous nezvinhu zvinoramba zvakaita sesimbi yakakandwa, mhangura nealuminium. Muzviitiko zvisina kunaka zvakaita sekubvisa ngura muzvinhu zvakakandwa uye kubvisa ngura musimbi, yave sarudzo yakajairika mumaindasitiri nekuda kwekushanda kwayo kwepamusoro-soro.
Kunyangwe girini silicon carbide uyekabhidhi nhema yesiliconZvine chekuita nesilicon carbide material system, hunhu hwazvo hwepanyama uye hwemakemikari uye hunhu hwekushandiswa zvakasiyana zvakanyanya. Nekuvandudzwa kuri kuramba kuchiitwa kwesainzi yezvinhu uye tekinoroji yekugadzirisa, green silicon carbide uye black silicon carbide zvinotarisirwa kuwedzera kushandiswa kwayo muminda yepamusoro-soro senge kugadzira semiconductor, kukuya kwakaringana, uye simba idzva, zvichipa rutsigiro rwakakosha rwekusimudzira indasitiri yemazuva ano.
