Quick Summary

Reaction-bonded silicon nitride (RBSN) is a type of advanced ceramic. Ceramics are inorganic, nonmetallic solids known for their hardness, strength, and brittleness. Advanced ceramics, like RBSN, are manufactured with precise control over composition and processing to achieve superior properties.1

RBSN is made by shaping fine silicon powders and then heating them in a nitrogen atmosphere. The nitrogen reacts with the silicon to form silicon nitride within the pores of the material. This process results in a "net shape" product, meaning it has excellent dimensional control and requires minimal post-firing machining. RBSN is valued for its good high-temperature strength and resistance to creep.21
