1. a preparation method for nano aluminum nitride powder, is characterized in that:

  • (1) aluminium source, water-soluble carbon source and auxiliary is adopted to be raw material;

    (2) by various raw material according to certain mol proportion wiring solution-forming, wherein the mol ratio in water-soluble carbon source and aluminium source is 1 ~ 3, and the mol ratio in auxiliary and aluminium source is 0.2 ~ 4;

    (3) solution is heated, after solution evaporation, concentrated formation gelatinoid, decomposition reaction occurs, obtain precursor powder;

    (4) by presoma in 1200-1800 DEG C of temperature range, under certain atmosphere, react 1-5 hour, obtain reaction product;

    (5) by reaction product in 500-800 DEG C of temperature range, in atmosphere process 1-3 hour, obtain aluminium nitride powder.
