A predominantly β''-sialon-bonded silicon carbide refractory article is produced by reaction-nitriding a green body containing a plurality of silicon carbide powders, none having an average particle size greater than about 200 micrometers, a metal oxide oxygen source
During this dead time, the inherent body diode of the MOSFET acting as a rectifier (either Q1 or Q2, depending on the phase of the switching cycle) conducts the full output current. When the device is reverse-biased in the next phase of the switching cycle, a large reverse-recovery current flows, causing power dissipation and electromagnetic interference, and canceling the efficiency gains made.

Appliion of Silicon Carbide in Abrasive Water Jet Machining 435 rapidly. It is worth mentioni ng that not all garnets are the same. There are wide variations in purity, hardness, sharpness, etc, that can al so affect the cutting speed and operating cost. Garnet is a
Gas transport mechanisms and the behaviour of impurities in the Acheson furnace for the production of silicon carbide W. R. Matizamhuka∗ Vaal University of Technology, Department of Metallurgical Engineering, South Africa ∗ Corresponding author. E-mail
The Acheson process still remains the method of choice for the industrial production of silicon carbide. The furnace operates in an unsteady thermal regime thus making it difficult to determine the kinetics of the process. In the present study, FactSage Software was used to get an insight and verify the dominant reactions occurring during operation. Moreover, the effect of impurities on the
