Silicon nitride components may be produced in dense form from a powder through the conventional sintering or hot-pressing routes. An interesting and important feature of the material, however, is that lower density (2300–2700 kgm –3) components may be produced directly by the nitridation of compacted silicon powder—the reaction-bonding (or reaction-sintering) route.

Silicon nitride ceramics have several excellent properties and clear advantages over other structural materials, but many potential applications are still not realized. A breakthrough in their use is inhibited not only by the high costs of the components for the automotive market; but also by a large scatter of the property data such as strength, fracture toughness, and reliability, plus

Reaction bonded silicon nitride (RBSN) is made by heating a compact volume of silicon powder in a nitrogen gas atmosphere. The reaction starts at 1200 °C, and Nitrogen-hydrogen or nitrogen-hydrogen-helium gas mixtures are used most often as they give faster and more easily controlled reactions, and result in higher strength materials .
