✦ Synopsis

The conditions leading to spurrite formation in the kiln have been simulated by laboratory studies, using reagent-grade reactants. Fluorine, and to a lesser extent chlorine, (F , CI ) are effective mineralizers, but direct synthesis of spurrite without mineralizers is only achieved if Ca3SiO 5 is used as a reactant. Both types of reaction are considered to be feasible in kilns, with kiln dust being the likely source of transported Ca3SiO 5. Water vapour introduced with CO 2 is not effective in enhancing spurrite formation.
