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.

Melt Filtration

The best-known composite is SiSiC ceramics, which is produced by infiltration of silicon melt in porous bodies made of silicon carbide. The so-called LSI process (Liquid Silicon Infiltration) is also used to infiltrate porous bodies made of carbon or SiC fibres, whereby CMC components (Ceramic Matrix Composites) are produced.

PROCESSING, MICROSTRUCTURE, AND PROPERTIES OF …

Silicon carbide (SiC) is a ceramic material with high strength and high hardness [1]. However, it displays brittle behavior and has low resistance to fracture [1]. Several methods to increase the fracture toughness of bulk SiC include modifying the SiC grain size and shape [2]

Formation of silicon carbide nanocrystals by high

Based on X-ray diffraction analysis, Auger spectroscopy, and Raman stering, it is shown that carbonization of porous silicon at temperatures of 1200–1300°C results in formation of silicon carbide nanocrystals 5–7 nm in size. The growth of 3C-SiC nanocrystals of fixed size d proceeds as follows. Silicon nanocrystals with d = 3–7 nm pass into the liquid phase, thereby effectively
