Abstract
In contrast with some other hydrous aluminum phosphates, vashegyite is crystalline. Simultaneous application of several assumptions leads to the hypothesis that it has a structure analogous to that of kaolinite, and thus contains tetrahedral sheets, n[X2O5], where X is both P and H3 (in lieu of Si). Thus, the theory involving [HXO4] is extended from phosphates with isolated tetrahedral groups [XO4] and framework linkages [XO2] to sheet linkages [X2O5]. Kingite also may have a kaolinite-like structure.Keywords
