Hi guys, i'm assume that you already know the 7 crystal system, each crystals have unique way of determining the family of planes, for example in cubic, we all know (111) plane is same (-1-1-1), and so on ((-1-11),(-11-1)...) a total of 8, in fact there is pattern to determine how many possible planes does a miller indices (hkl) can have in each crystal, so now my problem is, how to determine all family of planes in hexagonal, based on literature for h is not equal to k, k is not equal to l and h is not equal to l, there are 24 possible planes you could have, but what are those 24? for example in hexagonal you have (123) plane and you could have 24 family of planes, but what are the basis or rules to determine the maximum possible families of planes? please help thanks.(adsbygoogle = window.adsbygoogle || []).push({});
