What determines the extent of solid solution?<br />
1. Comparative sizes of atoms, ions or groups<br />
substitution is no problem<br />
>30% size difference --> substitution will not occur<br />
2. Charges of ions: need to maintain electroneutrality<br />
3. Temperature: more substitution at higher temperature<br />
Why? Because increased thermal vibrations increase site sizes
