A method for manufacturing micropowder is provided, which includes (a) mixing a silicon precursor and a carbon precursor to form a mixture, and heating and keeping the mixture at 1600&#xb0; C. to 1800&#xb0; C. under a vacuum and non-oxygen condition for 120 to 180 minutes to form a silicon carbide powder; and (b) heating and keeping the silicon carbide powder at 1900&#xb0; C. to 2100&#xb0; C. under non-oxygen condition for 5 to 15 minutes, and then cooling and keeping the silicon carbide powder at 1800&#xb0; C. to 2000&#xb0; C. under the non-oxygen condition for 5 to 15 minutes to form micropowder, wherein the micropowder includes a silicon carbide core covered by a carbon film.
