Abstract:
The state of Al3+, Ga3+ and Si4+ in erionites obtained by hydrothermal crystallization from Ga−Al−Si gels has been examined. The results suggest that gallium cations can isomorphously substitute a part of silicon cations in the zeolite framework, to a notable extent in the sites having no aluminium cations in the second coordination sphere of silicon.
Исследовано состояние катионов Al3+, Ga3+ и Si4+ в эрионитах, полученных гидротермальной кристаллизацией из галлийалюмосиликатных гелей. Показано, что катионы галлия способны изоморфно замещать часть катионов кремния цеолитного каркаса преимущественно в местах, не имеющих катионов алюминия во второй координационной сфере.
