Spinel Structure Yam ntxwv
Tus qauv cuspite yog ib qho qauv tsim cubic kaw, uas muaj plaub qhov chaw quadripartite, ob qhov chaw quadripartite tau nyob, thiab lwm qhov ob qhov chaw quadripartite yog khoob. Cov qauv no yog tus cwj pwm los ntawm qib siab ntawm symmetry, uas yog tshwm sim los ntawm plaub axial symmetry ntawm lub atom kev npaj nyob rau hauv lub cell thiab lub symmetry ntawm lub reflecting nto. Tsis tas li ntawd, cov qauv ntawm spinite kuj muaj cov yam ntxwv hauv qab no: 1. High kaw packing: cov atoms nyob rau hauv cov qauv ntawm spinite yog teem heev ze, ua rau lub cev ceev heev, yog li nws muaj siab hardness thiab lub zog.2. complex tshuaj muaj pes tsawg leeg: cov atoms nyob rau hauv cov qauv ntawm spinel tuaj yeem yog cov ntsiab lus sib txawv, yog li nws tuaj yeem tsim ntau yam sib txawv, uas muaj ntau yam ntawm daim ntawv thov nqi.3. Me me coefficient ntawm thermal expansion: cov atoms nyob rau hauv lub spinel qauv yog teem heev ze, yog li ntawd lub thermal expansion coefficient ntawm siv lead ua yog me me thiab muaj thermal stability.4. Sib nqus: Qee qhov sib xyaw hauv cov qauv spinel yog sib nqus thiab tuaj yeem siv rau kev npaj cov khoom sib nqus.Rau lub hauv paus ntawm cov qauv spinel, ntau yam sib txawv kuj tuaj yeem tsim los ntawm kev qhia lwm cov atoms lossis kev sib cais hauv cell, xws li manganese ferrite. , aluminate thiab lwm yam. Cov tebchaw no muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg thiab tuaj yeem siv rau hauv hluav taws xob, sib nqus, kho qhov muag thiab lwm yam. Yog li ntawd, cov qauv spinel muaj ntau yam kev siv qhov tseem ceeb thiab tau txais kev kawm dav dav thiab siv rau hauv cov khoom siv science thiab chemistry.
