Reaction hot pressing

WebReaction-bonded silicon nitride (RBSN) is made from finely divided silicon powders that are formed to shape and subsequently reacted in a mixed nitrogen/hydrogen or nitrogen/helium atmosphere at 1,200 to 1,250 °C (2,200 to 2,300 °F). The nitrogen permeates the porous body and reacts with the silicon to form silicon nitride within the pores. WebPress Ctrl+Period (.).
