Nitride-bonded silicon carbide ceramics have lower processing costs than many other SiC-based ceramics and adequate properties for use as high-temperature heat exchangers in oxidizing environments. Silicon nitride has much better resistance to attack by chlorine at temperatures above 900 C than silicon carbide.
Silicon Nitride, syalon or Sialon are beta ceramics which are sintered under high temperatures at 1,800 degrees celsius and can be made in almost any shape. As Sialon ceramics contain approximately 40% of Aluminium Oxide, they have excellent non-wetting properties when in contact with molten aluminium.
