Yog cov khoom amorphous tau khaws cia ntawm qhov kub thiab txias qis dua nws cov ntsiab lus melting rau lub sijhawm ntev, cov khoom molecules, atoms, lossis ions tuaj yeem maj mam rov qab mus rau hauv qhov siab dua. xaj crystalline daim ntawv. Crystals muaj ntse, zoo-txhais cov ntsiab lus melting; amorphous solids tsis.
Amorphous puas tuaj yeem ua crystalline ntawm cua sov?
Amorphous khoom tuaj yeem ua crystalline tsuas yog tias peb siv cov kuab tshuaj sib txawv rau crystallization, los ntawm cua sov thiab lim sai. Tom qab ua tiav pom cia kom txias txias li sai tau. Lub compound tsim yuav yog kinetically crystalline tab sis tsis thermodynamically.
Yuav ua li cas thaum cov khoom amorphous raug cua sov?
Ib qho amorphous tsis muaj lub ntsiab lus melting ntse tab sis melts tshaj qhov ntsuas kub. Piv txwv li, iav ntawm cua sov ua ntej softens thiab ces melts tshaj qhov kub thiab txias. Cov iav, yog li ntawd, tuaj yeem ua pwm lossis tshuab ua ntau yam duab. Amorphous khoom tsis muaj cov yam ntxwv ntawm kev sib xyaw ua ke.
Cov khoom amorphous hloov mus ua crystalline li cas?
Txoj kev yooj yim tshaj yog hloov nws los ntawm cua sov kom txog thaum nws melting point thiab ces txias nws sai sai (Nrog kua N2). Qhov no yuav tiv thaiv recrystallization, Ib qho cua sov yav tom ntej yav tom ntej nws qhov kub thiab txias yuav ua rau recrystallization.
Puas amorphous solids crystallize?
Tsis zoo li cov khoom crystalline,ib qho amorphous khoom yog ib qho khoom uas tsis muaj kev txiav txim sab hauv. Qee qhov piv txwv ntawm cov khoom amorphous muaj xws li roj hmab, yas, thiab gels. iav yog ib qho tseem ceeb heev amorphous khoom uas yog ua los ntawm kev ua kom txias ntawm cov khoom sib xyaw ua ke kom nws tsis crystallize.
