Qhov sib txawv tseem ceeb ntawm zinc blende thiab pob zeb diamond qauv yog zinc blende muaj zinc thiab sulfur atoms hauv nws cov qauv thaum pob zeb diamond qauv tsuas muaj cov pa roj carbon atoms hauv nws cov qauv.
Cov qauv ntawm zinc blende crystals zoo ib yam li cov qauv ntawm pob zeb diamond. Ob qho tib si cov qauv no yog cubic siv lead ua tshuab, tab sis lawv muaj cov atom sib txawv hauv lawv lub tsev cell. Yog li, muaj qhov sib txawv ntawm zinc blende thiab pob zeb diamond qauv.
Zib Zinc Blende yog dab tsi?
Zinc blende yog lub npe ntawm cov pob zeb siv lead ua ntawm zinc sulfide (ZnS). Nws yog pob zeb diamond zoo li lub network. Ntxiv mus, nws yog thermodynamically nyiam dua lwm hom zinc sulfide xws li wurtzite. Txawm li cas los xij, nws tuaj yeem hloov nws cov qauv thaum hloov qhov kub thiab txias. Piv txwv li, zinc blende tuaj yeem ua wurtzite yog tias peb hloov qhov kub.
Daim duab 01: Chav Cell ntawm Zinc Blende
Peb tuaj yeem ua tus yam ntxwv ntawm zinc sib xyaw ua lub cubic kaw-packed (CCP) thiab lub ntsej muag-centred cubic qauv (FCC). Tsis tas li ntawd, cov qauv no yog denser dua li cov qauv wurtzite. Txawm li cas los xij, thaum kub nce, qhov ntom ntom yuav txo qis; Yog li ntawd, kev hloov pauv tuaj yeem tshwm sim los ntawm zinc blende rau wurtzite. Tsis tas li ntawd, cov cations nyob rau hauv cov qauv no (zinc ions) nyob ib qho ntawm ob hom tetrahedral qhov tam sim no nyob rau hauv cov qauv, thiab nws muaj plaub asymmetric units nyob rau hauv nws chav tsev cell.
Pob zeb diamond yog dab tsi?
Pob zeb diamond yog ib qho allotrope ntawm carbon. Nws yog ib qho khoom siv ntawm cov pa roj carbon monoxide uas muaj cov duab peb sab. Ntxiv mus, txhua cov pa roj carbon atom txuas rau plaub lwm cov pa roj carbon atom ntawm covalent tshuaj sib txuas. Cov qauv siv lead ua no hu ua "pob zeb diamond cubic" qauv.
Daim duab 02: Chav Cell ntawm Pob Zeb Diamond
Tsis tas li ntawd, ntawm tag nrho cov khoom siv ntuj tsim, qhov sib xyaw no muaj qhov nyuaj tshaj plaws thiab thermal conductivity. Yog li ntawd, pob zeb diamond feem ntau siv hauv kev lag luam rau kev txiav thiab polishing cov cuab yeej.
Qhov txawv ntawm Zinc Blende thiab Pob Zeb Diamond Structure yog dab tsi?
Zinc blende thiab pob zeb diamond muaj cov qauv zoo sib xws. Qhov sib txawv tseem ceeb ntawm zinc blende thiab pob zeb diamond qauv yog zinc blende muaj ob qho tib si zinc thiab sulfur atoms hauv nws cov qauv thaum pob zeb diamond qauv tsuas muaj carbon atoms hauv nws cov qauv. Ntxiv mus, ob lub atoms nyob rau hauv lub hauv paus ntawm lub ntsej muag-centered cubic lattice ntawm zinc bende yog zoo tib yam thaum ob lub atoms nyob rau hauv lub hauv paus ntawm lub ntsej muag-centered cubic lattice ntawm lub pob zeb diamond qauv yog sib txawv ntawm ib leeg.
Summary – Zinc Blende vs Pob Zeb Diamond Structure
Zinc blende thiab pob zeb diamond muaj cov qauv zoo sib xws. Qhov sib txawv tseem ceeb ntawm zinc blende thiab pob zeb diamond qauv yog zinc blende muaj ob qho tib si zinc thiab sulfur atoms hauv nws cov qauv thaum pob zeb diamond qauv tsuas muaj carbon atoms hauv nws cov qauv.
