The invention relates to a method for preparing fluorophlogopite biomaterial powder through a sol-gel technology. The method comprises the following steps: preparing a Mg(NO3)2.6H2O and NH4F mixed solution (I) and a Al(NO3)3.9H2O and CO(NH2)2 mixed solution (II), uniformly mixing the mixed solution (I) with the mixed solution (II) to obtain a mixed solution (III), introducing F ions and Na ions under water bath and stirring conditions, adding silica sol, adjusting the pH value of the mixed solution to be neutral or acidic in order to obtain a suspension, carrying out sealed ageing on the suspension, carrying out pumping filtration on obtained white jelly, washing, drying, and calcining to obtain the fluorophlogopite biomaterial powder with the particle size of 100-200nm. The preparation method of the fluorophlogopite biomaterial powder has the advantages of high purity and good uniformity of the above product, low production cost, simple process, and easy realization of industrial production.
