PROBLEM TO BE SOLVED: To provide a large ceramic plate having heightened shape maintainability at a thermal shock time, concerning a large ceramic plate having a comparatively high linear expansion coefficient.SOLUTION: In a large ceramic plate, a linear expansion coefficient specified in JISR1618(2002) is 5.5×10to 10.0×10/°C, and a water absorption rate specified in JISA5209(2008) is 0.2% to 3.0%. In the large ceramic plate, it is further preferable that a glaze layer having a smaller linear expansion coefficient than the linear expansion coefficient of the ceramic plate is provided on the surface of the large ceramic plate.SELECTED DRAWING: None |
