  • Silicon Nitride (Si3N4) and Sialons - Fraunhofer IKTS

    Silicon nitride (Si 3 N 4) is a non-oxide ceramic material with a unique combination of outstanding properties. These include a high fracture toughness (5-8 MPa·m ½) in combination with a high flexural strength (800-1000 MPa) and a low coefficient of thermal expansion (3.5·10-6 K-1). This leads for example to an excellent thermal shock resistance.
