Preparation of the System of BaO-MgO-Al₂O₃-TiO₂ Acid-Resistant Fracturing Proppants

Abstract:

In order to improve the acid resistance and reduce the apparent density of fracturing proppants, TiO₂ powder added in the system of BaO-MgO-Al₂O₃ fracturing proppants were prepared by the technique of pressureless sintering. The properties of the samples were investigated by the measurements of acid solubility, X-ray diffraction and scanning electron microscopy. The results show that the acid solubility of alumina matrix fracturing proppants contenting TiO₂ of the 4wt% and BaO/MgO with the ratio of 3:7 is 0.15%. It is an important development in acid resistance performance of fracturing proppants research on laboratory. TiO₂ is added to the raw materials and then calcine them to ceramics, which can reduces the sintering temperature, promote the densification and improve acid-resistant property of fracturing proppants.
