A New “Incipient‐Wetness” Method for the Synthesis of Chemically Stabilized β‐Cristobalite

A new “incipient‐wetness” method is proposed for the synthesis of chemically stabilized β‐cristobalite (CSC) that avoids the need to handle liquid phases as required by the sol‐gel routes proposed in the literature. Stoichiometric compounds with the composition Si 1–x Al * x Ca 1/2 O 2 have been investigated. ×= 0.07 represents the optimal composition for obtaining an extremely well‐crystallized material consisting of a single β‐cristobalite phase. XRD, FTIR, DSC, and differential dilatometry have been used for the physicochemical characterization of the samples.
