110004, China) Abstract: Two-step sintering process was adopted to prepare fiber/NiFe2O4 composite ceramic inert anodes with copper-coated carbon fiber by solid-state reaction. NiFe2O4 spinel matrix... the above NiFe2O4 spinel matrix material and copper-coated carbon fiber as raw materials. The effects of addition of copper-coated carbon fiber on the bulk density, porosity and bending strength were studied......
Synthesis and characterization of tungsten and barium co-doped La2Mo2O9 by sol-gel process for solid oxide fuel cellsChang’an Tian,Lingbo Shao,Dongdong Ji,Jie Yang,Jinsong Xie,Qiyi Yin,Huirong... and decomposition properties of the LBMWO gel were analyzed by differential scanning calorimetry-thermogravimetric. The results reveal that all LBMWO powders calcined at 700 ℃ have a cubic structure......
