| abstract | PROBLEM TO BE SOLVED: To provide a member for molten metal comprising a silicon nitride sintered body which is excellent in mechanical properties and thermal shock resistance, can be used for a long period of time and has high reliability. Comprising a silicon nitride sintered body having a columnar crystal 1 and a grain boundary phase 2 mainly composed of an oxide of a metal element, and having open pores 3 on the surface of the silicon nitride based sintered body. 3 is a member for a molten metal in which a plurality of second columnar crystals 1b having a diameter larger than that of the first columnar crystal 1a existing in the silicon nitride sintered body are interlaced with each other. By suppressing the erosion of the grain boundary phase 2 on the inner surface of the open pores 3 by the molten metal, the mechanical properties and thermal shock resistance of the silicon nitride based sintered body itself can be improved. Further, since the molten metal is less likely to react with the grain boundary phase 2 and adhere firmly, it can be used for a long period of time. [Selection] Figure 1 |
