Shin robobin mu na yau da kullun sune crystalline ko amorphous?Da farko, muna buƙatar fahimtar menene mahimmancin bambanci tsakanin crystalline da amorphous.
Lu'ulu'u ne atoms, ions ko kwayoyin da aka tsara a cikin sarari bisa ga wani lokaci-lokaci don samar da wani m tare da wani na yau da kullum siffar geometric a lokacin da crystallization tsari.Amorphous jiki ne mai amorphous, ko amorphous, amorphous m, wanda yake shi ne mai ƙarfi wanda atom ba a tsara shi a cikin wani tsari na sararin samaniya, daidai da crystal.
Lu'ulu'u na yau da kullun sune lu'u-lu'u, ma'adini, mica, alum, gishiri tebur, jan karfe sulfate, sukari, monosodium glutamate da sauransu.Amorphous gama gari sune paraffin, rosin, kwalta, roba, gilashi da sauransu.
Rarraba lu'ulu'u yana da faɗi sosai, kuma yawancin abubuwa masu ƙarfi a cikin yanayi sune lu'ulu'u.Gases, tayal da abubuwa masu amorphous kuma ana iya canza su zuwa lu'ulu'u a ƙarƙashin wasu yanayi masu dacewa.Tsarin lokaci-lokaci mai girma uku na tsari na atom ko kwayoyin halitta a cikin crystal shine mafi mahimmanci kuma mahimmancin fasalin crystal.
Jikunan amorphous na gama gari sun haɗa da gilashi da mahaɗan polymer da yawa kamar su styrene da sauransu.Muddin adadin sanyaya yana da sauri isa, kowane ruwa zai samar da jiki mara kyau.Daga cikin su, zai yi sanyi sosai, kuma lattice ko kwarangwal a cikin yanayin ma'auni na thermodynamically crystalline zai rasa saurin motsi kafin a shirya atom ɗin, amma har yanzu ana ci gaba da rarraba kusan adadin atom ɗin a cikin yanayin ruwa.
Sabili da haka, zamu iya yin hukunci cewa robobi na yau da kullum a rayuwa suna da amorphous.
