Abstract
Crystals from the boracite family, M3B7O13X, have regained interest in the last 5 years owing to their interesting properties at the domain walls [1,2]. Indeed, charged domain walls form spontaneously on cooling through the phase transition. To develop a better understanding of the origin of the change in conduction at the domain walls and the apparent negative capacitance, we intend to study other boracite materials of properties similar to Cu-Cl, namely Mg-Cl and Cr-Cl boracite.
Due to the high-volatility of chlorine, boracite is not usually the stable phase when considering simple solid-state synthesis. We show that by tailoring the calcination conditions thoroughly the pure boracite phase can be obtained. In particular, the effect of temperature, pressure and calcination atmosphere on the synthesis yield are reported.
