Silicon carbide synthesis

摘要

This disclosure concerns a method of making silicon carbide involving adding agricultural husk material to a container, creating a vacuum or an inert atmosphere inside the container, applying conventional heating or microwave heating, heating rapidly, and reacting the material and forming silicon carbide (SiC).

主权项

1. A method of making SiC comprising:
adding agricultural husk material to a container; wherein the container is a covered boron nitride crucible;creating a vacuum or an inert atmosphere inside the container;
applying heat; heating the agricultural husk material; wherein the step of heating is accomplished by using a millimeter-wave beam and wherein the frequency of the millimeter-wave beam is about 83 GHz, the total beam power is about 5 kW, and the power density is about 0.3 kW/cm2; and reacting the agricultural husk material and forming silicon carbide; wherein the silicon carbide is nanoparticles and nanorods of SiC in a pure form.
