Ibisobanuro by'ibicuruzwa

Ifu itukura ya amorhous, ihinduka umukara muguhagarara na kristu yo gushyushya; Ifishi ya vitreous na colloidal irashobora kwitegura.

Ifishi ya Amorhous Softens kuri 40 ° C hamwe na Melts kuri 217 ° C. Ni gake bibaho muri leta y'amateka muri kamere, cyangwa nk'ibice byera.
