Description

Kristali naj bi bili omejeni z ravnimi ploskvami in koti med njimi naj bi bili vedno enaki, vendar to ne drži povsem. Rast kristalov in njihova končna oblika je odvisna predvsem od njihove simetrije ter geometrije njihove pritrditve na podlago. Oblika kristalnih ploskev je odvisna od prostorske porazdelitve nabojev na površini kristalov v času njihove rasti, ki pa je zopet odvisna od snovne simetrije. Končna oblika kristala z določeno simetrijo pa je tudi odraz pogojev v času rasti, predvsem od hitrosti spreminjanja tlaka in temperature ter prisotnosti posameznih substanc v mediju iz katerega kristali.
