Abstract:
1. A method for production of silicon carbide powder comprising: a first step of putting a liquid mixture including a silicon source, a carbon source containing no amine, and a polymerizing or cross-linking catalyst inside a container, introducing an argon gas into the liquid mixture contained in the container, and discharging a released gas out of the container; a second step of placing the container in which the liquid mixture is placed in a drying chamber, and reducing the internal pressure of the container, and producing a solid of the liquid mixture by drying the liquid mixture in the drying chamber, and a third step of placing the produced solid in a heating furnace, and producing silicon carbide powder by carbonating the solid in the heating furnace, wherein the carbon source containing no amine is a phenolic resin synthesized without using an amine-based catalyst.
