Molybdenum acid solution, method for producing same, molybdenum oxide powder, and method for producing same
This molybdic acid solution contains 0.1-40 mass% of molybdenum in terms of MoO3, and has a particle diameter (D50) of 20 nm or less as determined by particle diameter distribution measurement using a dynamic light scattering method. The method for producing a molybdic acid solution according to the present invention comprises: a step in which an acidic molybdenum aqueous solution containing molybdenum in an amount of 1-100 g/L in terms of MoO3 is added to 10-30% by mass of an aqueous ammonia solution to produce a molybdenum-containing precipitate; and adding an organic nitrogen compound to the molybdenum-containing precipitate slurry obtained by making the molybdenum-containing precipitate into a slurry state to generate a molybdic acid solution.
本发明的钼酸溶液是含有以MoO3换算计0.1～40质量％的钼的钼酸溶液，通过使用了动态光散射法的粒径分布测量而得到的粒径(D50)为20nm以下。另外，本发明的钼酸溶液的制造方法具有下述的工序：将含有以MoO3换算计1～100g/L的钼的酸性钼水溶液添加至10～30质量％的氨水溶液中，生成含钼的沉淀；以及在将所述含钼的沉淀制成浆料状而得到的含钼的沉淀浆料中添加有机氮化合物，生成钼酸溶液。
