HALSIC is the name of four exceptional high performance ceramics from the silicon carbide (SiC) material group made by W. HALDENWANGER. They share the following characteristics: absolute dimensional stability despite extreme mechanical strain in high temperature appliions – very good thermal shock resistance – excellent high corrosion resistance – low specific weight.

We are proud to introduce these grinding disks made with silicon carbide grains. They are designed with a flat grain curve that will not flatten after a few appliions. They are a good alternative to SiC abrasive paper and SiC grinding foils (films), lasting 50-100 times longer.
Silicon carbide, SIC, with a hardness of about 2,500 HV, is a widely used abrasive for grinding papers for mainly non-ferrous metals. Aluminium oxide, with a hardness of about 2,000 HV, is primarily used as an abrasive in grinding stones.
Reaction bonded SiC bars 76 ]7]6mm3in size (HD530, NortonCompany,Worcester, MA)wereused for the joining experiments. This material consisted mainly of alpha-silicon carbide crystals with a bimodal grain-size distribution (approximately 10 and 100 lm)

Silicon (Si)-based IGBTs have been on the market for more than 30 years. The technology has quickly evolved, reducing the costs and improving performance at the same time. As Si devices approach their physical limits, wide-band-gap devices, in particular made from silicon carbide (SiC), have emerged on the market, offering better performance thanks to their intrinsic properties.
Silicon carbide (SiC) nanorods were synthesised by reacting multi-walled carbon nanotubes (CNTs) with Si particles in a NaCl–NaF binary salt for 4 h at 1100–1200 C in Ar. Reaction products were analysed by a coination of X-ray diffraction (XRD) and transmission electron microscopy (TEM), including aberration corrected lattice imaging and electron energy loss spectroscopy (EELS).

Abstract—Silicon carbide (SiC) MOSFET has the po-tential to replace silicon (Si) IGBT due to its superior switching performance. However due to presence of para-sitic inductance in converter layout, device voltage and cur-rent experience overshoots and loss.
Silicon carbide (SiC) is ideally suited for power switching because of its high saturated drift velocity, its high critical field strength, its excellent thermal conductivity, and its mechanical

The natural occurrence of silicon carbide was first reported by Moissan (1905) from the Canyon Diablo meteorite. It was first found in terrestrial rocks in the Green River Formation of Wyoming by Regis and Sand (1958) and was identified as the low temperature cubic ß-SiC polymorph.
Moreover, silicon carbide itself is an important semiconductor for the electronics industry providing a ready integration of graphene electronics with devices produced on the SiC. Graphene electronics imposes great demands on the material and material processing.
