Bicchulite has an ideal chemical formula of 2CaO •Al2O3 •SiO2 •H2O which was formularized from the hydrothermal synthesis of synthetic gehlenite (2CaO •Al2O3 •SiO2). Also bicchulite was sighted in the mines of Japan with related minerals. This sodalite-type structured bicchulite has an uncommon ratio of aluminium to silicon causing difficulties deciphering the structure.
