Green silicon carbide black silicon carbide and silicon carbide two commonly used the base of the varieties, are alpha SiC. Black silicon carbide containing SiC by about 95%, the toughness is higher than the green silicon carbide, mostly used for processing low tensile strength of material, such as glass, ceramics, stone, refractory material, cast iron and nonferrous metal, etc.
Researchers say silicon photonics—optical circuits based on silicon chips—are one of the leading platforms for such technologies, thanks to their compatibility with existing microelectronics. “We’ve seen an explosion of growth in silicon photonic technologies the past few of years,” said Peter Rakich, an associate professor of applied physics at Yale who led the research.

15/2/2020· Plasma Etching of Silicon Carbide K. Zekentes, J. Pezoldt, V. Veliadis Plasma etching is the only microelectronics-industry-compatible way to etch SiC for the device pattern transfer process. After more than twenty years of SiC plasma etching technology development, there are still issues such as (i) the etch-rate dependence on plasma parameters, (ii) the surface roughness, […]

Silicon Nitride Ceramics Silicon nitrides (Si3N4) are a range of advanced engineering ceramics characterised by high strength, toughness and hardness and excellent chemical and thermal stability. Silicon nitride was discovered in the mid-nineteenth century but did not lend itself to ease of fabriion, due to its covalently bonded nature. This initially led to the development […]
Porous silicon carbide merane supports were prepared using alumina and yttria additives (1–4 wt%) with various weight ratios of Al2O3/Y2O3 (23/77–60/40) and sintering at 1500–1800 C.
Crystallization of diamond in the Mg-Si-C system has been studied at 7.5 GPa and 1800 °C with the Mg-Si compositions spanning the range from Mg-C to Si-C end-systems. It is found that as Si content of the system increases from 0 to 2 wt %, the degree of the graphite-to-diamond conversion increases from about 50 to 100% and remains at about this level up to 20 wt % Si. A further increase in Si
