Cermet alloys combustion synthesis

These materials are normally prepared by mechanical mixing of oxides, but the combustion method is also used to produce impurity-free materials with high specific surface area. A perovskite (SrTiFe03.5)-alloy (PtRu) cermet is obtained directly by combustion synthesis (fig.l). It presents a low crystallinity, low Pt crystal size ( 15nm) and a specific surface area of 48.5 mVg.
