The direction and spacing of the planes with reference to the unit cell axes are defined by the Miller indices {hkl}.
WebAccording to Pauling's rules for crystal structures, the allowed size of the cation for a given structure is determined by the critical radius ratio. If the cation is too small, then it will attract the anions into each other and they will collide hence the compound will be unstable due to anion-anion repulsion; this occurs when the radius ...
