Kuj hu ua silica xuab zeb lossis quartz xuab zeb, silica yog silicon dioxide (SiO2). Silicon compounds yog qhov tseem ceeb tshaj plaws ntawm cov khoom Lub ntiaj teb crust . Txij li cov xuab zeb yog plentiful, yooj yim rau kuv thiab kuj yooj yim rau txheej txheem, nws yog thawj qhov chaw ntawm silicon. Lub pob zeb metamorphic, quartzite, yog lwm qhov chaw.

Ib yam li ib tug yuav nug, qhov twg yog Silicon feem ntau pom?

Silicon : piav qhia Silicon yog tam sim no nyob rau hauv lub hnub thiab hnub qub thiab yog ib feem tseem ceeb ntawm ib chav kawm ntawm meteorites hu ua aerolites. Silicon ua 25.7% ntawm lub ntiaj teb crust los ntawm qhov hnyav, thiab yog qhov thib ob feem ntau ntau lub caij, tshaj tsuas yog los ntawm oxygen.

Kuj Paub, silicon mined li cas? Silicon yog tsim los ntawm cua sov xuab zeb (SiO2) nrog cov pa roj carbon mus rau qhov kub ntawm 2200 ° C. Ntawm chav sov, silicon muaj nyob rau hauv ob hom, amorphous thiab crystalline. SiO2 yog khawb av ob qho tib si raws li xuab zeb thiab raws li cov hlab ntsha los yog lode deposits, siv rau hauv kev lag luam.

Kuj paub, dab tsi yog 5 siv silicon?

Hyperpure silicon tuaj yeem doped nrog boron, gallium, phosphorus, lossis arsenic los tsim silicon siv rau hauv transistors, solar cells, rectifiers, thiab lwm yam khoom siv hauv lub xeev uas tau siv dav hauv cov khoom siv hluav taws xob thiab chaw hnub nyoog.

Qhov twg siv silicon?

Lub ntsiab silicon yog siv Feem ntau raws li ib tug semiconductor nyob rau hauv solid-state li nyob rau hauv lub computer thiab microelectronics industries. Rau qhov no, hyperpure silicon yog xav tau. Cov silicon yog xaiv doped nrog me me ntawm boron, gallium, phosphorus los yog arsenic los tswj nws cov khoom hluav taws xob.
