Production of Fine, High‐Purity Beta Silicon Carbide …

At lower temperatures (below approximately 1400 C), the dominant mechanism for silicon carbide formation involves the solid‐state reaction of silica and carbon. At higher temperatures (above approximately 1400°C), the dominant mechanism is the reaction between gaseous SiO and C. Above 1400°C, the rate of SiC formation is controlled by the rate of SiO formation.
