| Abstract: | The waste electrolyte of aluminum-air battery was taken as the raw material to produce aluminum hydroxide by crystal seed decomposition. The results show that with the decomposition time of 24 h and the seed coefficient of 2%~4%, the ultrafine alumina hydroxide can be produced with a narrow particle size distribution and an excellent flame retardant performance, which can meet HG/T4530-2013, the professional standard for flame retardant ATH-1 of alumina hydroxide. |

| Keywords: | ultrafine aluminum hydroxide flame retardant seed decomposition aluminum-air battery waste electrolyte |
