摘要：

It is argued on crystal-chemical grounds that Si deficiency is compensated by the entering of Al, Fe**3<, or Ti**4<, in this order of preference, into tetrahedral sites. It is pointed out that Ti**4< occurs in tetrahedral coordintion in exceptional circumstances only, while Fe**3< relatively easily occurs in tetrahedral coordination in exceptional circumstances only, while Fe**3< reltively easily takes a tetrahedral coordination.
