Mineral crystals form nyob rau hauv ntau cov duab sib txawv thiab qhov ntau thiab tsawg. A ntxhia yog tsim los ntawm atoms thiab molecules. Raws li cov atoms thiab molecules ua ke, lawv tsim ib qho qauv. Qhov kawg puab ntawm ntxhia qhia txog qhov qub atomic puab.

Ua raws li qhov no hauv kev xav, yuav ua li cas crystals sib txawv hauv cov zaub mov?

Rau ib ntxhia tsim a siv lead ua , nws xav tau chaw kom loj hlob. Nrog rau qhov chaw txaus, siv lead ua loj hlob hauv pab pawg kom tsim tau loj dua crystalline cov qauv. Tab sis tsis yog tag nrho siv lead ua muaj cov qauv zoo ib yam ntawm qhov chaw tiaj tus. Ib txhia siv lead ua muaj cov duab cubes.

Kuj Paub, dab tsi yog pob zeb siv lead ua zoo li? Hauv kev xaus, tus cwj pwm, los yog pom puab ntawm a siv lead ua , yog ib lub cev khoom uas yuav siv tau los pab txheeb xyuas cov ntxhia . Ib txhia siv lead ua yog euhedral raws li lawv muaj ib txwm, polygonal qauv . Euhedral cwj pwm muaj xws li octahedral, xws li pob zeb diamond, dodecahedral, xws li garnets, thiab cubic, xws li halite thiab galena.

Tsis tas li ntawd, cov crystals tsim los ntawm cov ntxhia sib txawv tib yam?

Hais kom yooj yim, a siv lead ua yog ib tug qauv tsim los ntawm ntau yam khoom ntuj whereas a ntxhia yog ib yam khoom nyob rau hauv nws tus kheej. Ob lossis ntau dua cov ntxhia tuaj yeem muaj qhov tseeb ib yam tshuaj muaj pes tsawg leeg thiab tseem txawv kiag li thaum nws los txog rau siv lead ua qauv. Cov no yog hu ua polymorphs.

Cov duab zoo li cas crystals tuaj rau hauv?

Muaj kev ntseeg tias muaj xya cov duab los yog "systems" nyob rau hauv uas crystals tau daim ntawv. Lawv suav nrog cubic, hexagonal, tetragonal, orthorhombic, monoclinic, thiab triclinic.
