    • There is provided a production method in which highly transparent fine metal hydroxide particles having a small particle size and excellent in monodispersibility can be easily produced without requiring grinding. The method for producing fine metal hydroxide particles at least includes: a reaction step of mixing an aqueous solution of a metal salt, for example, a magnesium salt, with an aqueous solution of a hydroxide salt to precipitate metal hydroxide particles in an uncrystallized state; a purification step of removing by-product salt from a mixed solution containing the precipitated metal hydroxide particles in an uncrystallized state; a surface treatment step of treating the metal hydroxide particles in an uncrystallized state obtained through the purification step with a surface-treatment agent on the surface thereof; and a heating step of crystallizing the surface-treated metal hydroxide particles in an uncrystallized state by hydrothermal treatment.
    • 提供了一种制造方法,其中可以容易地生产具有小粒径和优异的单分散性的高度透明的细金属氢氧化物颗粒,而不需要研磨。 金属氢氧化物微粒的制造方法至少包括:将金属盐(例如镁盐)的水溶液与氢氧化物盐的水溶液混合的反应步骤,以沉淀未结晶状态的金属氢氧化物粒子; 从含有沉淀的金属氢氧化物颗粒的未结晶状态的混合溶液中除去副产物盐的纯化步骤; 表面处理步骤,通过表面处理剂处理通过纯化步骤获得的未结晶状态的金属氢氧化物颗粒; 以及通过水热处理使表面处理的金属氢氧化物颗粒在未结晶状态下结晶的加热步骤。
