Abstract
PURPOSE:To obtain a silicon nitride sintered body for a cutting tool having superior strength and toughness by sintering and heat treating a mixture of prescribed percentages of Si3N4 powder, nonstabilized ZrO2 powder, Al2O3 powder and Y2O3 powder under prescribed conditions. CONSTITUTION:A powdery mixture consisting of, by weight, 1-10% nonstabilized ZrO2 powder, 1-5% Al2O3 powder, 1-10% Y2O3 powder and the balance Si3N4 powder, is sintered at 1,600-1,900 deg.C in an inert gaseous atmosphere and this sintered body is heat treated at 1,200-1,600 deg.C in a nonoxidizing atmosphere.
