内容: | There are provided a method for dividing a ceramic cylindrical body, involving forming first and second notched portions in an inner periphery surface of the ceramic cylindrical body at positions confronting each other in the diametrical direction and subsequently applying a compressive load in the diametrical direction to divide the cylindrical body along the first and second notches, thereby making it possible to afford divided surfaces having such a concave and a convex as prevent axial displacement when re-joining divided sections, as well as a shape of the notched portions. Bisected cylindrical body portions can be joined together closely without axial displacement of the joined cylindrical body. |
