Qhov sib txawv tseem ceeb ntawm Q Carbon thiab Pob Zeb Diamond yog Q carbon (los yog quenched carbon) muaj cov qauv random, whereas pob zeb diamond muaj pob zeb diamond cubic siv lead ua qauv.
Q carbon thiab pob zeb diamond yog allotropes ntawm carbon. Allotropes yog cov qauv txheej txheem sib txawv ntawm tib yam tshuaj lom neeg. Lwm hom allotrope ntawm carbon yog graphite. Ntxiv mus, pob zeb diamond suav hais tias yog cov khoom siv tawv tshaj plaws hauv ntiaj teb. Txawm li cas los xij, raws li kev tshawb fawb zaum kawg, Q carbon tau hloov pob zeb diamond ua cov khoom hnyav tshaj plaws.
Q Carbon yog dab tsi?
Q carbon (quenched carbon) yog ib qho allotrope ntawm carbon. Cov khoom tau pom nyob rau hauv 2015. Nws yog ferromagnetic, hluav taws xob conductive khoom. Tsis tas li ntawd, cov khoom no ci ntsa iab thaum peb nthuav tawm nws mus rau qib qis zog. Piv rau pob zeb diamond, nws pheej yig los ua. Raws li qee qhov kev tshawb fawb tsis ntev los no, Q carbon nyuaj dua pob zeb diamond.
Tsis tas li ntawd, cov khoom siv no muaj cov qauv random amorphous, thiab nws muaj sp 2 hybridized carbon atoms thiab sp3hybridized carbon atoms li zoo. Tsis tas li ntawd, nws cov txheej txheem ntau lawm suav nrog melting carbon (siv nanosecond laser pulses) thiab quenching sai. Qee zaum, qhov no muab qhov sib xyaw ntawm Q carbon thiab pob zeb diamond.
Khoom ntawm Q Carbon
- Non-crystalline qauv
- sib xyaw Sp2thiab sp3dending
- Unique hardness
- Ua hluav taws xob
- Kev ntsuas kub
- Daim ntawv cog lus me me dua li pob zeb diamond
- Ferromagnetic
- Yuav ua tau semiconductor lossis metallic
- Glows txawm nyob rau theem qis zog
pob zeb diamond yog dab tsi?
Pob zeb diamond yog ib qho allotrope ntawm carbon thiab suav tias yog cov khoom siv nyuaj tshaj plaws uas tshwm sim hauv ntiaj teb. Nws cov qauv yog crystalline, thiab nws muaj pob zeb diamond cubic siv lead ua qauv. Ntxiv mus, nws muaj lub siab tshaj plaws thermal conductivity ntawm tej yam ntuj tso khoom. Pob zeb diamond tsim ntawm qhov kub thiab txias heev hauv lub mantle ntawm lub ntiaj teb (100 mais hauv qab ntawm qhov chaw).
Daim duab 01: Pob zeb diamond
Properties of Diamond
- Feem ntau xim av lossis daj hauv cov xim, tab sis kev lag luam hniav nyiaj hniav kub nyiam cov pob zeb tsis muaj xim
- Zoo meej octahedral cleavage hauv 4 cov lus qhia
- Contains sp3 hybridized carbon atoms
- Thaum muab piv rau cov khoom siv engineering, tawv tsis zoo.
- Exceptionally yield zog
- Zoo hluav taws xob insulators
- Lipophilic thiab hydrophobic
- Ntawm chav sov, pob zeb diamond tsis hnov mob nrog cov tshuaj reagent
Qhov txawv ntawm Q Carbon thiab Pob Zeb Diamond yog dab tsi?
Q carbon yog quenched carbon, uas yog ib qho allotrope ntawm cov pa roj carbon thaum lub pob zeb diamond, kuj yog ib qho allotrope ntawm carbon, suav hais tias yog cov khoom nyuaj tshaj plaws uas ib txwm tshwm sim hauv ntiaj teb. Qhov sib txawv tseem ceeb ntawm Q Carbon thiab pob zeb diamond yog tias Q carbon muaj cov qauv random, whereas pob zeb diamond muaj pob zeb diamond cubic siv lead ua qauv. Cov qauv no ua rau Q carbon cov khoom siv nyuaj tshaj plaws; lub sijhawm no, pob zeb diamond yog cov khoom siv nyuaj tshaj plaws tshwm sim hauv ntiaj teb.
Qhov sib txawv ntawm Q Carbon thiab pob zeb diamond yog tias Q carbon yog cov khoom siv hluavtaws thaum lub pob zeb diamond tshwm sim ib txwm muaj. Ntxiv mus, hauv Q carbon, ob leeg sp2 and sp3 hybridized carbon atoms tuaj yeem pom thaum, hauv pob zeb diamond, tsuas yog sp 3 hybridized carbon atoms tam sim no. Yog li, peb tuaj yeem coj qhov no los ua qhov sib txawv ntawm Q Carbon thiab pob zeb diamond. Thaum xav txog qhov tsim, rau Q carbon, ua ntej peb yuav tsum yaj cov pa roj carbon (siv nanosecond laser pulses) thiab quench sai heev los tsim Q carbon whereas pob zeb diamond tsim nyob rau hauv kub heev kub thiab pressures nyob rau hauv lub mantle ntawm lub ntiaj teb (100 mais hauv qab ntawm qhov chaw)..
Summary – Q Carbon vs Diamond
Hauv luv luv, Q carbon thiab pob zeb diamond yog allotropes ntawm cov tshuaj lom neeg carbon. Qhov sib txawv tseem ceeb ntawm Q Carbon thiab pob zeb diamond yog tias Q carbon muaj cov qauv sib txawv thaum lub pob zeb diamond muaj lub pob zeb diamond cubic siv lead ua qauv. Ntxiv mus, Q Carbon nyuaj dua pob zeb diamond, tab sis pob zeb diamond yog cov khoom siv nyuaj tshaj plaws uas tshwm sim hauv ntiaj teb.
