PRODUCTION METHOD OF METAL NITRIDE, IGNITION AGENT AND IGNITION AGENT COMPACT

To provide a production method of a metal nitride, or the like, capable of progressing efficiently a nitriding reaction of a raw material by transmitting combustion heat generated by ignition of an ignition agent surely to base powder.SOLUTION: In a production method of a metal nitride, an ignition agent burial part where an ignition agent is buried is provided in a base powder layer containing metal powder, and the metal powder is nitrided and burned by igniting the ignition agent under a nitrogen atmosphere. In the production method of a metal nitride or the like, the ignition agent burial part has at least one of at least one internal corner part extending in a depth direction, a concave surface part and a hole part.SELECTED DRAWING: Figure 1 【課題】着火剤の着火による燃焼熱を確実に原料粉末へ伝搬させて、当該原料の窒化反応を効率よく進行させる金属窒化物の製造方法等を提供する。【解決手段】金属粉末を含む原料粉末層に着火剤を埋設した着火剤埋設部を設け、窒素雰囲気下で前記着火剤を着火させて前記金属粉末を窒化燃焼させる金属窒化物の製造方法であって、前記着火剤埋設部が、深さ方向に延びる少なくとも１つの入隅部、凹面部、及び孔部の少なくともいずれかを有する、金属窒化物の製造方法等である。【選択図】図１
