Abstract

Abstract

In this study, magnesium oxide (MgO) doped by cobalt (Co) was prepared as pressure-transmitting medium, by solid reaction process.The starting material is a pre-compressed mixture of MgO and cobalt oxide (CoO), which was mixed for 8 h and compressed at 200 MPa, and then treated at 1 200℃.The as-prepared samples were characterized by X-ray diffraction, scanning electron microscopy, and thermogravimetric analysis.The results demonstrate that during the sintering process, the reaction between MgO and CoO was completed and the exchange of metal ions between MgO and CoO leads to a single solid solution phase.Compared to the domestic products (MgO+10wt% Na₄SiO₄), there is no impurity found in Co-doped MgO, which is more stable than the domestic products under high pressure and high-temperature.In addition, the temperature-generation efficiency of the cell assembly with MgO+9mol% CoO as pressure-transmitting medium is also higher than that of the domestic products.
