Silicon Nitride (Si3N4)

Silicon nitride is a light gray to black ceramic, which is used in high-temperature technology in particular because of its good mechanical properties up to 1800° C. Silicon nitride ceramics are characterized by a low density, high fracture toughness, low coefficient of friction and very good thermal shock resistance. However, their properties are highly dependent on the manufacturing process used and the additives added.
