    Abstract: A method of producing nano metal fluoride powders comprising the steps of mixing an aqueous or organic continuous phase comprising at least one metal cation salt with a hydrophilic or organic polymeric disperse phase forming a metal cation salt/polymer gel and then treating said gel with anhydrous hydrofluoric acid to convert said metal cation salt to metal cation fluoride and heat treating the gel at a temperature sufficient to drive off water and/or organics within the gel, leaving a residue of nano-size metal fluoride powder.

    Abstract translation: 一种制备纳米金属氟化物粉末的方法,包括以下步骤:将包含至少一种金属阳离子盐的水性或有机连续相与形成金属阳离子盐/聚合物凝胶的亲水或有机聚合物分散相混合,然后用无水氢氟酸处理所述凝胶 酸以将所述金属阳离子盐转化为金属阳离子氟化物,并在足以驱除凝胶内的水和/或有机物的温度下热处理凝胶,留下纳米尺寸金属氟化物粉末的残余物。
