Silicon simbi yekugadzirisa fekitori inopa 553 3303 silicon simbi

Metal silicon, inozivikanwawo secrystalline silicon kana silicon yeindasitiri, inonyanya kushandiswa sechinhu chinowedzera kune asiri-ferrous alloys.Metal silicon chigadzirwa chakanyungudutswa kubva kuquartz uye coke muvira remagetsi.Chinhu chikuru chesilicon yemukati chinenge 98% (mumakore achangopfuura, 99.99% yeSi content inosanganisirwa musimbi silicon), uye iyo yakasara tsvina isimbi nealuminium.calcium, nezvimwewo.

Zvivakwa uye zvakanakira ferrosilicon

1. Kupisa kwekushisa kwepamusoro, kunyange mushure mekupisa kwe-ultra-high arc kupisa, kurasikirwa kwehuremu kuduku zvikuru, uye iyo yekuwedzera kwekushisa coefficient iduku zvakare.Simba resilicon yesimbi rinowedzera nekuwedzera kwekushisa, uye pa 2000 ° C, simba resimbi silicon rinowedzera kaviri.

2. Electrical uye thermal conductivity, conductivity yesimbi silicon yakakwira zvakapetwa ka100 kupfuura yeakajairika asiri-metallic minerals.Thermal conductivity inodarika iyo yezvinhu zvesimbi zvakaita sesimbi, iron, uye lead.Iyo yekupisa conductivity inoderera nekuwedzera kwekushisa, uye kunyangwe pakupisa kwakanyanya, simbi silicon inova insulator yekupisa.Simbi silicon inogona kuitisa magetsi nekuti yega kabhoni atomu musimbi silicon inongogadzira matatu covalent bond nemamwe maatomu ekabhoni, uye atomu imwe neimwe kabhoni ichiri kuchengeta 1 erekitironi yemahara kutakura machaji.

3. Lubricity.Iko kuita kwekuzora kwesimbi silicon kunoenderana nehukuru hwesimbi silicon zviyero.Iyo yakakura zviyero, iyo idiki iyo friction coefficient uye zvirinani kuita kwekuzora.

4. Kugadzikana kwemakemikari.Metal silicon ine yakanaka kugadzikana kwemakemikari pane tembiricha yekamuri, uye inogona kuramba asidhi, alkali uye organic zvinonyungudutsa.

5. Plasticity, metal silicon ine kusimba kwakanaka uye inogona kukungurutswa kuita masheets matete kwazvo.

6. Thermal shock resistance.Kana yakashandiswa pakamuri tembiricha, simbi silicon inogona kumira zvakanyanya kuchinja kwekushisa pasina kukuvara.Kana tembiricha ikangoerekana yachinja, huwandu hwesimbi silicon haichinji zvakanyanya, uye hapana kutsemuka kuchaitika.
