ESD-Safe Silicon Carbide

ESD silicon carbide is a grade of silicon carbide. The graph bars on the material properties cards below compare ESD silicon carbide to other non-oxide engineering ceramics (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
