Uruganda rutunganya ibyuma bya silicon rutanga ibyuma bya silicon 553 3303

Silicon y'ibyuma, izwi kandi nka silikoni ya kristaline cyangwa silikoni yo mu nganda, ikoreshwa cyane nk'inyongera ku mavuta adafite ferrous.Silicon yicyuma nigicuruzwa cyashongeshejwe muri quartz na kokiya mu itanura ryamashanyarazi.Ibyingenzi bigize silicon yibigize hafi 98% (mumyaka yashize, 99,99% yibirimo bya Si nabyo biri muri silicon yicyuma), naho umwanda usigaye ni fer na aluminium., calcium, nibindi

Ahanini ikoreshwa nkibikoresho fatizo byibikoresho bya silicone polymer, nka: Silicon imwe, metallurgical casting.smelting
Ibicuruzwa bivura imiti, ibikoresho bivunika, aluminium na aluminiyumu yinganda zitanga umusaruro, nibindi

Ibyiza nibyiza bya ferrosilicon

1. Kurwanya ubushyuhe bwinshi, na nyuma yubushyuhe bukabije bwa arc gutwika, gutakaza ibiro ni bito cyane, kandi coefficente yo kwagura ubushyuhe nayo ni nto.Imbaraga za silicon yicyuma yiyongera hamwe nubushyuhe bwubushyuhe, naho kuri 2000 ° C, imbaraga za silicon yicyuma zikuba kabiri.

2. Amashanyarazi nubushyuhe, amashanyarazi ya silicon yicyuma yikubye inshuro 100 ugereranije nubutare busanzwe butari ubutare.Ubushyuhe bwumuriro burenze ubwibikoresho byibyuma nkibyuma, ibyuma, na gurş.Ubushyuhe bwumuriro buragabanuka hamwe no kwiyongera kwubushyuhe, ndetse no mubushyuhe bwo hejuru, silikoni yicyuma iba insulator.Silicon yicyuma irashobora kuyobora amashanyarazi kuko buri atome ya karubone muri silicon yicyuma ikora gusa imiyoboro 3 ya covalent hamwe nandi atome ya karubone, kandi buri atome ya karubone iracyafite electron 1 yubusa kugirango yishyure.

3. Amavuta.Imikorere yo gusiga ibyuma bya silicon biterwa nubunini bwumunzani wa silicon.Umunzani munini, ntoya ya coefficient de fraisse nuburyo bwiza bwo gusiga amavuta.

4. Imiti ihamye.Silicon y'ibyuma ifite imiti ihamye yubushyuhe bwicyumba, kandi irashobora kurwanya aside, alkali na solge organic.

5. Plastike, silicon yicyuma ifite ubukana bwiza kandi irashobora kuzunguruka mumabati yoroheje cyane.

6. Kurwanya inkuba.Iyo ikoreshejwe mubushyuhe bwicyumba, silicon yicyuma irashobora kwihanganira impinduka zikomeye zubushyuhe nta byangiritse.Iyo ubushyuhe buhindutse gitunguranye, ingano ya silicon yicyuma ntabwo ihinduka cyane, kandi ntagishobora kubaho.
