Tape Casting of Silicon Nitride
Keyword(s):
ABSTRACTTape casting behavior of submicron silicon nitride powder(UBE SN–E1O) with Al2O3 and Y2O3 as sintering additives was studied. It was found that Hypermer KD1(polymeric dispersant) is effective dispersant for submicron silicon nitride in organic solvent system.Optimization of the rheological properties of the slurries allows the homogeneous green tapes with green densities of 45–50% theoretical. The cast tapes could be sintered to closed porosity with densities of higher than 96% theoretical.
