Production of Silicon Carbide in a High Frequency Electromagnetic Field. Measuring Thermal Conductivity

Materials like alumina and silicon carbide, sensitive to high frequency electromagnetic field are very useful for processing other materials in the high frequency electromagnetic field. The use of these sensitive materials can enhance a more uniform temperature alignment over a hot material in a high frequency electromagnetic field. These silicon carbide composites will be loaded with enriched cement. In this article, we will also discuss the factors that influence the heating rate of composed materials. These factors depend on the size of the silicon carbide particles, the percentage of silicon carbide in the volume of the composite material, the treatment atmosphere and the maximum experimental temperature. The heating rate of the composite materials was determined as the amount of silicon carbide increased while the heating rate increased. The size of the silicon carbide particles also influenced the heating rate of the composite material, which has been demonstrated experimentally. Mathematical model has shown that the effect of particle size is a geometric one dependent on a non-perfect thermal contact between the silicon carbide particle and the cement patern. The size of the silicon carbide particles also affected the filtration threshold of the composite materials. The heating rate of the composite materials grew when the calcium carbonate in the cement was pyrolyzed to form calcium oxide due to an growth in thermal conductivity.
