強磁場中スリップキャストによるSiCウイスカー分散Al₂O₃の配向

抄録

Developing texture is one possible way for improving the properties of ceramics. Texture in ferromagnetic materials can be tailored by a magnetic field, but it had been difficult to produce texture in diamagnetic and paramagnetic materials, such as silicon carbide and alumina, because their susceptibility is very small. A well-dispersed suspension of SiC (w)-Al₂O₃ was prepared and consolidated by slip casting in a high magnetic field. The Al₂O₃ matrix with a slight degree of orientation was observed in the green body and the degree of texture increased by annealing.
