Abstract
Official abstract text for this publication.
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° C. to 1800° 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° C. to 2100° C. under non-oxygen condition for 5 to 15 minutes, and then cooling and keeping the silicon carbide powder at 1800° C. to 2000° 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.
First claim
Opening claim text (preview).
What is claimed is: 1. Micropowder, comprising: a silicon carbide core; and a carbon film covering the silicon carbide core, wherein the silicon carbide core has a diameter of 50 micrometers to 500 micrometers, and the carbon film has a thickness of 20 nm to 200 nm, wherein the micropowder is a hexagonal structure. 2. The micropowder as claimed in claim 1 , having an emission wavelength of 400 nm to 550 nm.
