Measuring Silicon Carbide Particle Size - Horiba

Silicon carbide (SiC) has a range of physical properties that makes it a versatile and useful material. It is one of the hardest materials known, second only to diamond, has a relatively low density (approximately the same as aluminum), good wear and corrosion resistance and low thermal expansion and high thermal conductivity leading to excellent thermal shock resistance.

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
