Reaction Bonded Silicon Nitride/Si3N4 Sheet
Goodfellow's Reaction Bonded Silicon Nitride/Si3N4 sheets are ceramic sheets made by reaction bonding of silicon powder and silicon nitride. With high hardness and strength at elevated temperatures, as well as good thermal shock and oxidation resistance, they have applications in automotive engine components, gas turbines and cutting tools. We offer Si3N4 sheets in 6 variations with minor differences in density, porosity, and grain size to accommodate different high-temperature engineering needs.
