In the present research, ultrafine SiC nanoparticles were fabricated using SiC scrap, and their physical properties were optimized with a pulverization method. Their particle sizes were controlled with the pulverization time, and ultrafine SiC nanoparticles with sizes below 40 nm were achieved. Also, thick film heaters was made by using the ultrafine SiC nanoparticles. A small amount of graphene materials were added to the SiC nanoparticles to heat the thick film at a relatively low resistance below 1,000 Omega. Enhanced heating properties was achieved by adding graphene with a higher specific surface area (SSA) to the SiC nanoparticles, and a thick-film heater showing a temperature of 310 degrees C was achieved by using the SiC-graphene with a higher SSA.
