Method for Preparing Silicon Nitride Sintered Body and The Silicon Nitride Sintered Body Prepared by The Same
The present invention relates to a method for manufacturing a silicon nitride sintered body which comprises a step of thermally treating raw material powder which is prepared by mixing silicon nitride powder and an oxide-based sintering aid; and a step of sintering a resultant undergone the step of thermal treatment, wherein the resultant undergone the step of thermal treatment comprises 70 to 90 parts by weight of α-silicon nitride and 10 to 30 parts by weight of β-silicon nitride; and a silicon nitride sintered body manufactured thereby. According to the present invention, a silicon nitride sintered body having high intensity can be manufactured.
