Abstract
A new structural model for zeolite A (rhombohedral R3) differs from the one currently accepted (cubic Fm3c) in that each tetrahedrally co-ordinated Si4+ion is surrounded, via oxygen bridges, by three (not four) Al3+ ions and one Si4+ ion, and each Al3+ion by three (not four) Si4+ and one Al3+.Keywords
