Cermet anode and preparation method and application thereof
The invention belongs to the technical field of electrode materials, and particularly relates to a cermet anode and a preparation method and application thereof. The invention provides a cermet anode which comprises an open-pore foam metal matrix and ceramic, wherein the ceramic comprises filling ceramic filled in pores of the open-pore foam metal matrix and a ceramic outer layer positioned on the outer surface of the open-pore foam metal matrix; the material of the open-pore foam metal matrix is copper or nickel; the material of the ceramic is doped NiO-NiFe2O4 ceramic; and the doped NiO-NiFe2O4 ceramic comprises a NiO-NiFe2O4 ceramic matrix and a doped oxide. According to the cermet anode, the open-pore foam metal matrix forms a metal phase of a communicated netlike structure, and the filling ceramic filled in the pores of the open-pore foam metal matrix also forms a ceramic phase of a communicated netlike structure, so that the conductivity, thermal shock resistance and mechanical strength of the cermet anode are improved.
本发明属于电极材料技术领域,特别涉及一种金属陶瓷阳极及其制备方法和应用。本发明提供了一种金属陶瓷阳极,包括通孔泡沫金属基体和陶瓷,所述陶瓷包括填充在所述通孔泡沫金属基体孔隙中的填充陶瓷和位于所述通孔泡沫金属基体外表面的陶瓷外层;所述通孔泡沫金属基体的材质为铜或镍;所述陶瓷的材质为掺杂的NiO‑NiFe2O4陶瓷,所述掺杂的NiO‑NiFe2O4陶瓷包括NiO‑NiFe2O4陶瓷基体和掺杂氧化物。本发明中通孔泡沫金属基体形成连通网状结构的金属相,填充在所述通孔泡沫金属基体孔隙中的填充陶瓷亦形成具有连通网状结构的陶瓷相,有利于提高金属陶瓷阳极的导电性、抗热震性能和机械强度。
