ST’s silicon-carbide diodes take advantage of SiC’s superior physical characteristics over Si, with 4 times better dynamic characteristics and 15% less forward voltage, VF. Their low reverse recovery characteristics make ST’s silicon-carbide diodes a key contributor to energy savings in SMPS appliions and in emerging domains such as solar energy conversion, EV or HEV charging stations

Bulk boron carbide was prepared using a commercial (5SA) benchtop 300 Amp arc melter. Commercial (Starck, Grade HD20) boron carbide powder (0.5 g) was first cold-pressed into a pellet and then melted in an argon flow. As the liquid cooled, millimeter-sized boron carbide crystals were formed on the surface of the ingot (fig. S1A).
Silicon carbide in contact with silicon carbide exhibits lower friction than unlubri- ed metals and retains it to much higher temperatures (refs. 1 and 2). Furthermore, the effect of crystallographic orientation and load on the Knoop microhardness of single- crystal silicon carbide …
A method for forming a polycrystalline ceramic fiber which comprises blending about 5 to about 25 weight percent polymer, about 70 to about 95 weight percent silicon carbide powder and greater than 1 weight percent sintering aid; forming a fiber from the blend; and sintering the formed fiber. Preferably, the sintering aid is boron carbide.

Silicon carbide (SiC) with its unique properties is expected to enable significant enhancements in the existing properties of CNTs to a far-ranging variety of appliions and systems. In this report SiC–CNT composites through the novel route of d.c. arc discharge technique using silicon powder as a filler in a graphite anode have been prepared.
Monotungsten carbide, WC, or Ditungsten Carbide, W 2 C, is a chemical compound containing tungsten and carbon, similar to titanium carbide. Its extreme hardness makes it useful in the manufacture of cutting tools, abrasives and bearings, as a cheaper and more heat-resistant alternative to diamond .
Fig. 1: SiC MOSFET. Source: Cree. SE: How about with SiC? Palmour: Silicon carbide has a 10 times higher breakdown field.Our 600-volt MOSFET is going to be as fast as a 60-volt silicon MOSFET. The other way to look at it is if you say 600 volts is the voltage at which you switch from MOSFETs and silicon over to IGBTs, we would be at 10 times higher voltage.
