【摘要】 本实验以无机盐为原料,采用溶胶凝胶法制备了La₂NiO₄薄膜,并在中性和弱还原气氛下得到了单一的K₂NiF₄相。该薄膜结构均匀,为一种多孔的纳米粒子膜。测试结果表明,La₂NiO₄薄膜具有良好的电阻温度稳定性和较好的氧敏特性.更多还原

【Abstract】 Thin film of La₂NiO₄ has been prepared by sol-gel process with nitrate as raw materials. Pure K₂NiF₄ phasecan be obtained after sintering in N₂ or H₂/N₂, atmosphere at 800℃. SEM indicate that this film is uniform and porous.The La₂NiO₄ film exhibit good oxygen sensitivity when tested in oxidizing/reducing atmosphere at 700-800℃.更多还原
