Ingabe amapulasitiki ethu avamile ayikristale noma ama-amorphous?Okokuqala, sidinga ukuqonda ukuthi yini umehluko obalulekile phakathi kwe-crystalline ne-amorphous.
Amakristalu ama-athomu, ama-ion noma ama-molecule ahlelwe emkhathini ngokwe-periodicity ethile ukuze akhe okuqinile okunomumo othize ojwayelekile wejometri phakathi nenqubo yokucwebezela.I-amorphous iwumzimba we-amorphous, noma i-amorphous, i-amorphous solid, eqinile lapho ama-athomu angahlelwanga ngokulandelana okuthile kwendawo, okuhambisana nekristalu.
Amakristalu avamile idayimane, i-quartz, i-mica, i-alum, usawoti wetafula, i-copper sulfate, ushukela, i-monosodium glutamate njalonjalo.I-amorphous evamile ipharafini, i-rosin, i-asphalt, irabha, ingilazi nokunye.
Ukusatshalaliswa kwamakristalu kubanzi kakhulu, futhi izinto eziningi eziqinile emvelweni zingamakristalu.Amagesi, uketshezi kanye nezinto ezi-amorphous nazo zingaguqulwa zibe amakristalu ngaphansi kwezimo ezithile ezifanele.Isakhiwo sezikhathi ezintathu-ntathu sokuhlelwa kwama-athomu noma ama-molecule ekristalu yisici esiyisisekelo nesibalulekile kakhulu sekristalu.
Imizimba evamile ye-amorphous ihlanganisa ingilazi kanye nezinhlanganisela eziningi ze-polymer ezifana ne-styrene nokunye.Inqobo nje uma izinga lokupholisa lishesha ngokwanele, noma yiluphi uketshezi luzokwakha umzimba we-amorphous.Phakathi kwazo, kuzobanda kakhulu, futhi i-lattice noma uhlaka lwamathambo e-thermodynamically crystalline state luzolahlekelwa isivinini sokunyakaza ngaphambi kokuba ama-athomu ahlelwe, kodwa ukusatshalaliswa okulinganiselwe kwama-athomu esimweni se-liquid kusagcinwa.
Ngakho-ke, singakwazi ukwahlulela ukuthi amapulasitiki avamile ekuphileni angama-amorphous.
