Qhov Tseem Ceeb Qhov txawv - Tetrahedral vs Octahedral Voids
Thaum txiav txim siab ntim cov khoom tsis zoo, muaj qhov khoob uas hu ua voids. Voids yog unoccupied, khoob qhov chaw ntawm chav tsev cell nyob rau hauv cov khoom inorganic. Ib chav tsev cell yog ib qho tseem ceeb chav tsev uas qhia tau hais tias cov tshuaj npaj ntawm tag nrho cov khoom uas yog tsim los ntawm rov ua units. Cov atoms, molecules los yog ions uas lub tshuab siv lead ua yog tsim los ntawm feem ntau hu ua spheres. Hauv cov khoom ntim zoo sib xws, muaj ob hom voids uas tuaj yeem pom; tetrahedral voids thiab octahedral voids. Qhov sib txawv tseem ceeb ntawm tetrahedral thiab octahedral voids yog tias tetrahedral voids pom nyob rau hauv cov khoom muaj tetrahedral siv lead ua tshuab whereas octahedral voids pom nyob rau hauv cov khoom muaj octahedral siv lead ua tshuab.
Tetrahedral Voids yog dab tsi?
Tetrahedral Voids tsis muaj nyob, qhov chaw khoob tam sim no hauv cov khoom muaj tetrahedral siv lead ua tshuab. Yog li ntawd, qhov void no tshwm sim nyob nruab nrab ntawm plaub qhov chaw. Lub void tetrahedral yog tsim thaum ib lub atom (los yog sphere) muab tso rau hauv kev nyuaj siab tsim los ntawm peb lwm atoms (los yog spheres). Yog li ntawd, ob txheej atomic tau koom nrog hauv kev tsim cov tetrahedral void.
Daim duab 1: Ob Tetrahedral Voids.
Txawm li cas los xij, cov duab ntawm tetrahedral void tsis yog tetrahedral, tsuas yog kev npaj ntawm plaub qhov nyob ib ncig ntawm qhov khoob yog tetrahedral. Cov duab ntawm voids yog qhov nyuaj heev. Qhov ntim ntawm tetrahedral void yog me dua li ntawm ib qho atom (los yog sphere) uas ua rau tsim cov void. Loj qhov loj ntawm cov khoom nyob ib ncig ntawm qhov khoob, qhov loj ntawm qhov khoob. Kev sib koom tes ntawm tetrahedral void yog plaub. Ntawm no, lub sij hawm sib koom tes tus lej sawv cev rau tus naj npawb ntawm atoms lossis ions tam sim ntawd nyob ib puag ncig qhov khoob. Hauv cov txheej txheem siv lead ua, muaj ob qhov voids ib leeg (atom). Cov voids thiab lawv qhov loj me no muaj kev cuam tshuam zoo rau cov khoom siv.
Octahedral Voids yog dab tsi?
Octahedral voids tsis muaj nyob, qhov chaw khoob tam sim no hauv cov khoom muaj octahedral siv lead ua tshuab. Ib qho octahedral void yog tsim nyob rau hauv nruab nrab ntawm rau atoms (los yog spheres). Nyob rau ntawd, peb lub atoms sib ze (los yog spheres) tsim ib daim duab peb sab sib npaug thiab muab tso rau lwm qhov peb lub atoms ua rau muaj qhov khoob. Ntawm no, kuj muaj ob txheej atomic koom nrog hauv kev tsim cov void.
Daim duab 2: Ib qho Octahedral void ntawm qhov nruab nrab ntawm chav tsev cell.
Qhov ntim ntawm qhov khoob octahedral yog qhov me me thaum piv nrog tetrahedral void. Thaum ib chav tsev cell ntawm ib yam khoom (muaj ib qho kev npaj octahedral) raug txiav txim siab, muaj ib qho octahedral void nyob rau hauv nruab nrab ntawm chav tsev cell, thiab tus naj npawb ntawm cov void no yog rau vim rau atoms nyob ib ncig ntawm nws. Nyob rau hauv ib tug siv lead ua lattice, muaj ib void rau ib tug kheej kheej (los yog atom).
Dab tsi zoo sib xws ntawm Tetrahedral thiab Octahedral Voids?
- Ob leeg yog voids tam sim no nyob rau hauv siv lead ua lattices.
- Ob leeg me dua li cov spheres uas tsim cov iav siv lead ua.
Qhov txawv ntawm Tetrahedral thiab Octahedral Voids yog dab tsi?

Summary – Tetrahedral vs Octahedral Voids
Voids yog qhov chaw khoob tam sim no hauv cov tshuab siv lead ua uas tshwm sim vim kev sib txawv ntawm cov atoms. Muaj ob hom voids lub npe hu ua tetrahedral void thiab octahedral void. Qhov txawv ntawm tetrahedral thiab octahedral voids yog tias tetrahedral void yog pom nyob rau hauv cov khoom uas muaj tetrahedral siv lead ua tshuab whereas octahedral void yog pom nyob rau hauv cov khoom muaj octahedral siv lead ua tshuab.
