| titleOfInvention | Silicon nitride sintered body and method for producing the same |
| abstract | (57) [Summary] Even if manufactured by sintering at a low temperature of 1600 ° C. or less, a machine that is at least as dense as a conventional silicon nitride sintered body and inherently high in silicon nitride sintered body. The present invention provides a silicon nitride sintered body having excellent mechanical strength, smoothness and good surface properties even in a sintered state, and suitable as various structural parts, and a method for producing the same. SOLUTION: At least one of erbium and holmium is converted to an oxide, 2 to 10% by mass, aluminum is converted to an oxide, 2.5 to 7% by mass, and magnesium is converted to an oxide, 1 to 10% by mass. A silicon nitride sintered body comprising 0.5 to 4% by mass and silicon nitride constituting the balance, and having a Vickers hardness of 1500 or more. |
