Ibisobanuro ku bicuruzwa

Ifu itukura ya Amorphous, ihinduka umukara uhagaze na kristaline ku gushyushya; imiterere ya vitreous na colloidal irashobora gutegurwa.

Ifishi ya Amorphous yoroshye kuri 40 ° C igashonga kuri 217 ° C. Ntibisanzwe bibaho muburyo bwibanze muri kamere, cyangwa nkibintu byamabuye meza.
