摘要：

The development of Hydrated Silicate Ionic Liquids, which are hypo-hydrated room temperature melts of alkali silicates, has created new opportunities for synthesizing porous silicate materials. Their discovery also allows to reinterpret the role of an ionic liquid for zeolite synthesis and offers unique opportunities to study crystallization in situ. The reduced complexity of HSILs together with a large space of achievable zeolitic phases and framework compositions, renders them excellent systems for modelling and computer simulations. This work summarizes the impact of alkalinity, hydration, and cation type on silicate speciation and provides physicochemical data spanning relevant temperatures and compositions for zeolite formation. The data is meant as a reference point to further accommodate and verify (computational) models. © 2024 Elsevier B.V.
