Late formation of silicon carbide in type II supernovae
We have found that individual presolar silicon carbide (SiC) dust grains from supernovae show a positive correlation between 49Ti and 28Si excesses, which is attributed to the radioactive decay of the short-lived ( t ½ = 330 days) 49V to 49Ti in the inner highly 28Si-rich Si/S zone. The 49V-49Ti chronometer shows that these supernova SiC dust grains formed at least 2 years after their parent

Effect of vanadium carbide on dry sliding wear behavior of
The wear resistance of compacts was studied by using rotating pin-on-disk and linearly reciproing ball-on-flat methods. Wear mechanisms were investigated by means of scanning electron microscopy (SEM) observations and chemical inspections of the microstructures of the samples. and silicon carbide (SiC) particles dispersed in a commercial

You can use Silicone Carbide belts dry on a conventional belt sander. This is a popular way for professional glaziers to edge polish or bevel glass shelves or tabletops. Avoid sanding too long or holding the sander in one place to avoid friction-generated heat burning off the grit from the belt. Spraying a little water onto the belt will
