High-entropy spinel phase ceramic inert anode material for carbon-free aluminum electrolysis as well as preparation method and application of high-entropy spinel phase ceramic inert anode material
The invention provides a high-entropy spinel phase ceramic inert anode material for carbon-free aluminum electrolysis as well as a preparation method and application of the high-entropy spinel phase ceramic inert anode material, divalent metal hydroxides and trivalent metal hydroxides are used as raw materials, and a high-entropy spinel phase is synthesized in situ through cold sintering, so that the high-entropy spinel phase ceramic inert anode material is obtained. The corrosion resistance of the ceramic inert anode material is improved through the hysteresis diffusion effect of the high-entropy spinel phase, the conductivity of the material is improved through the structural characteristics of the high-entropy spinel phase and the multi-element hybridization effect, and meanwhile the strength of the material is cooperatively improved through the strengthening effect of the high-entropy spinel phase and the advantages of the cold sintering process; the conductivity, the strength and the corrosion resistance of the prepared high-entropy spinel phase ceramic inert anode material are greatly improved.
本发明提供了一种无碳铝电解用高熵尖晶石相陶瓷惰性阳极材料、制备方法及应用，以二价金属氢氧化物、三价金属氢氧化物为原材料，通过冷烧结原位合成高熵尖晶石相，从而得到高熵尖晶石相陶瓷惰性阳极材料。本发明利用高熵尖晶石相的迟滞扩散效应来提升陶瓷惰性阳极材料的耐腐蚀性，并借助高熵尖晶石相的结构特点和多元素杂化效应来提高材料的导电性，同时借助高熵尖晶石相的强化效应和冷烧结工艺的优势来协同提高材料的强度，使得制备出的高熵尖晶石相陶瓷惰性阳极材料在导电性、强度和耐腐蚀性上都有了很大的提升。
