CERAMIC SINTERED BODY, CERAMIC HEATER AND GLOW PLUG
PROBLEM TO BE SOLVED: To improve the strength of a ceramic sintered body in a very high temperature environment.SOLUTION: A ceramic sintered body has a main phase containing crystals of silicon nitride, and a grain boundary phase between the main phases. The grain boundary phase contains RE4SiAlO8N crystals (where, RE is selected from erbium (Er), thulium (Tm), ytterbium (Yb), and lutetium (Lu)).SELECTED DRAWING: Figure 2
【課題】非常に高い温度温環境におけるセラミック焼結体の強度を向上させる。【解決手段】窒化珪素の結晶からなる主相と、主相同士の間に存在する粒界相と、を備えるセラミック焼結体において、粒界相は、ＲＥ４ＳｉＡｌＯ８Ｎの結晶（但し、ＲＥは、エルビウム（Ｅｒ）、ツリウム（Ｔｍ）、イッテルビウム（Ｙｂ）、ルテチウム（Ｌｕ）から選ばれる）を含む。【選択図】図２
