Sintering Sr2MgWO6 Ceramic and their Reactivity to Petroleum

This work has as main objectives to produce the ceramic Sr2MgWO6 and evaluate their reactivity to petroleum. Powders of SrCO3, MgO and WO3 were selected, taken in stoichiometric amounts and synthesized by conventional route. The synthesis was characterized by size distribution, specific surface area and thermogravimetric analysis (TGA). The synthesis was also fragmented into ball mill and characterized by specific surface. It was compacted, then was calcined at 1200 °C and analyzed by X-ray diffraction. The powders Sr2MgWO6 with perovskite structure were compacted and sintered at 1250, 1300 and 1350 °C. The materials produced were evaluated by microhardness, scanning electron microscopy (SEM), diffraction of X-rays and tests submersion in petroleum. The results showed that the ceramics have high microhardness and potential to be used in chemically aggressive environments such as petroleum.
