Ingcaciso yeMveliso

I-amorphous powder ebomvu, ibe mnyama ngokuma kunye nekristale ekufudumeni; iifom ze-vitreous kunye ne-colloidal zinokulungiswa.

Imo ye-amorphous iyathamba kwi-40 °C kwaye inyibilika kwi-217 °C. Ayifane yenzeke kwimo yayo yokuqala kwindalo, okanye njengeekhompawundi ezicocekileyo zentsimbi.
