Ib lub iav siv lead ua yog kev npaj ntawm cov atoms, lossis pawg ntawm atoms, hauv ib lub siv lead ua. Cov atoms lossis pawg ntawm atoms feem ntau hu ua cov ntsiab lus nyob rau hauv ib qho chaw siv lead ua lattice. Yog li, xav txog qhov chaw siv lead ua lattice uas muaj cov ntsiab lus sib xyaw ua ke hauv cov qauv tshwj xeeb nrog kev sib txuam siab.
Crystal lattice muaj dab tsi?
Crystals yog tsim los ntawm peb-dimensional qauv. Cov qauv no muaj xws li cov atoms lossis pawg ntawm cov atoms hauv kev txiav txim thiab kev sib xyaw ua ke uas tau rov ua dua nyob rau ib ntus ua kom tib qho kev taw qhia rau ib leeg.
Yuav ua li cas cov tebchaw muaj ib tug siv lead ua lattice?
Daim Ntawv Crystalline ntawm Ionic Compounds Kev npaj ntawm ions nyob rau hauv ib txwm, geometric qauv hu ua siv lead ua lattice. Piv txwv ntawm cov crystals yog cov alkali halides, uas suav nrog: potassium fluoride (KF) potassium chloride (KCl)
Yuav ua li cas siv lead ua lattice?
Lub 14 Bravais lattices tau muab faib ua xya lub lattice: triclinic, monoclinic, orthorhombic, tetragonal, rhombohedral, hexagonal, thiab cubic. Nyob rau hauv ib lub tshuab siv lead ua, ib pawg ntawm cov ntsiab lus thiab lawv qhov chaw sib raug zoo pab pawg raug muab rau hauv cov kab lattice.
Puas cov hlau puas muaj cov iav siv lead ua?
Ntau cov hlau thiab alloys crystallize nyob rau hauv ib qho ntawm peb cov qauv ntau heev: lub cev-centered cubic (bcc), hexagonal kaw packed (hcp), los yog cubic kaw packed (ccp, kujhu ua face centered cubic, fcc). Atoms nyob rau hauv metallic crystals muaj ib tug nyiam ntim nyob rau hauv ntom ntim uas sau qhov chaw zoo. …
