| titleOfInvention | Silicon nitride powder for silicon nitride sintered body, silicon nitride sintered body and method for producing the same |
| abstract | (57) [Summary] [Objective] A dense silicon nitride having a high fracture toughness value and excellent strength at a lower sintering temperature than when using β-type silicon nitride powder produced by a conventional direct nitriding method as a raw material. Obtain an elementary sintered body. [Structure] A nitrogen-containing silane compound and / or a sintered powder of an amorphous silicon nitride powder, and a β-type silicon nitride 8 0% by weight or more, a rare earth compound is contained in a concentration of 0.05 to 2.0% by weight based on a metal element, the average particle diameter of the constituent particles is 0.1 μm or more and 0.5 μm or less, and the aspect ratio is 2. Using β-type silicon nitride powder controlled to 5 or less, one or more selected from magnesium oxide, aluminum oxide, and oxides of Group IIIa elements of the periodic table After the addition of 0.2 to 6% by weight of the oxide of 1 to 100, the mixture is molded into 1 to 19 at 1 to 100 atm under nitrogen or a nitrogen-containing inert gas atmosphere. By firing at a temperature of 00 ° C. until the bulk density reaches 95% or more of the theoretical density, a silicon nitride sintered body having a high fracture toughness value and excellent strength is obtained. |
