초록
Kaolin과 규석 및 Mg(OH)2 등의 원료로 만들어진 slip을 casting 할 때 slip의 점도가 slip casting 속도와 소결체의 미세조직에 미치는 영향을 보면 slip-casting 속도는 slip의 점도가 낮을 경우 감소하였으며 slip의 점도범위는 3.0~17.0 cP가 적당하였다. Slip의 점도를 조절하면 표면층, 표면 내부층, 중간층, 내면층의 미세조직을 비교적 균일하게 casting 할 수 있다. 소성온도 1350 oC에서 시편의 구성광물은 cordierite 결정만으로 되어있었다.
Abstract
We have investigated the relationship between a viscosity of the slip prepared from kaolin, quartz, Mg(OH)2, etc and its influence on the speed of slip casting and the microstructure of a sintered body. The speed of slip casting decreases as a viscosity of a slip decreases. The optimized viscosity range of a slip was found to be around 3.0~17.0 cP. By careful controlling a viscosity of slip, homogeneous icrostructure of outer surface layers, inner surface layers, intermediate layers, and inside layers were obtained by casting process. The specimen sintered at 1350 oC consists of a cordierite crystalline phase only as a constituent mineral.
