Silicon carbide (SiC) is a lightweight ceramic material with high strength properties comparable to diamond. It has excellent thermal conductivity, low thermal expansion, and is resistant to corrosion from acids. Silicon carbide is an excellent ceramic material for applications requiring good erosion and abrasive resistance. Consequently, it is useful in a variety of applications including spray nozzles, shot blast nozzles and cyclone components.

Everything was packed into a box into 3 separate smaller boxes and in the 3 smaller boxes each set was then packed again into individual boxes. The largest shipping box had some shipping air cushions. Everything seemed OK. Good.
