Lub cev cov khoom ntawm cov hlau silicon (silicon hlau):
Atomic qauv:
Atomic tus naj npawb: 14
Atomic hnyav:28.085 G / Mol
Crystal qauv:Pob zeb diamond cubic lattice (zoo ib yam li pob zeb diamond thiab transmanium).
Cov tsos mob thiab xeev:
Bluish-grey, brittle crystalline khoom nrog nws yog xim hlau luster.
Khoom ntawm chav sov thiab txheem siab.
Thermal Khoom:
Melting taw tes:1,414 Kev Kawm Ntawv (2,577 degree f).
Boiling taw tes:3,265 degree (5,909 degree f).
Thermal Condivity:• 149 W / MIN KIS (Cov kub ua tau zoo tshaj plaws rau lub semiconductor).
Thermal nthuav tawm coefficient:2.6 × 10⁻⁶ K⁻¹ (Tsawg nthuav tawm txo cov kev ntxhov siab thermal).
Cov Khoom Siv Hluav Taws Xob:
Cov Hluav Taws Xob nrog qhov hluav taws xob tiv thaiv ntawm ~ 2.3 × 105 × 10 degree.
Conductivity nce nrog kub (intrinsic semiconductor tus cwj pwm).
Cov Khoom Siv Neeg Kho Tshuab:
Ntawj ntom:2.33 g / cm³ (2,330 kg / mp).
MoHS Hardness:~ 6,5 (sib piv rau quartz).
Brittleness:Muaj nkig heev; tsis muaj kev sib luag thiab kev sib xyaw ua ke.
Cov tub ntxhais hluas lub modulus:{{0 {0}} GPA (cov khoom tawv).
Qhov chaw kho tshiab:
Xav txog lub teeb pom kev ruaj khov.
Cov ntsiab lus tsis zoo: ~ 3.5 (ntawm ze-infrared wavelengths).
Cov Khoom Sib Nqus:
Diamnetic (tsis muaj zog repelled los ntawm cov hlau nplaum teb).
Isotopes:
Lawm ecurring isotopes: ²⁸SI (92.23%), ²⁹si (4.67%), 3.10%).
Key distintions:
Metallurgical-grade silicon (~98-99% purity) is less refined and more brittle than ultra-high-purity silicon (>99.99%) siv hauv cov khoom siv hluav taws xob.
Silicon lub pob zeb diamond yog cov ceg ntoo diamond nrog nws tus brittleness thiab siab yaj taw tes.
Cov ntawv thov tsav los ntawm cov khoom siv lub cev:
Thermal Condivity:Siv nyob rau hauv tshav kub so rau cov khoom siv hluav taws xob.
Semiconductivity:Hauv paus rau kev sib xyaw circuits thiab solar hlwb.
Tsawg thermal nthuav dav:Qhov zoo tagnrho rau kev kub-ib puag ncig (piv txwv li, cua sov (chaw sov).
