Silicon Nitride Rods

Gas pressure sintered silicon nitride (GPSSN) is a sintering processing at high temperature after isostatic pressing of silicon nitride powder with other additives. The nitrogen pressure (<20mpa) during sintering could restrain the dissociation of si3n4 and get the full sintering at high temperature, which make the silicon nitride products to highest density and lowest porosity.
