The main objectives of this work were the production of Ca2MgWO6ceramic by sintering and the investigation of its reactivity to crude petroleum. A synthesis was prepared with stoichiometric amounts of CaO, MgO and WO3. The reagents were characterized according to chemical composition. The synthesis was characterized by size distribution and thermal analysis. A green compact of the synthesis was calcined at 1200 °C and analyzed by XRD. The result showed that the calcined material consists predominantly of a complex perovskite-type Ca2MgWO6ceramic. The calcined material was fragmented in a ball mill and used to prepare three green compacted to be sintered at temperatures of 1250, 1300 and 1350 °C. The sintered material was evaluated by linear shrinkage, microhardness, SEM, microanalysis by dispersive energy and stability tests in crude petroleum. The results showed that it is possible to produce a material with 74.5 % of Ca2MgWO6and that is inert to crude petroleum.
