Talk:Kröger–Vink notation

Positive cations/negative cations
Can someone clarify the part on the Schottky effect where positively charged cations and negatively charged anions seem superfluous to me being not a trained chemist/physicist, but some say only the relative charges matter, but why then need it be a higher charged cation/anion pair?

You are right, talking about positive cations and negative anions is superfluous. I would either delete the words positiv/negative, or put them in brackets. Johannes Bo (talk) 20:21, 15 April 2014 (UTC)
