PROBLEM TO BE SOLVED: To prevent the collapse of piled stands for calcination. SOLUTION: This stand for calcination comprises a square plate-like ceramic plate, and is obtained by integrally forming standing legs 4, 4 at four upper corners, forming flat polished upper surface 5 on each standing leg 4, forming a flat polished lower surface 7 on the lower surface at least at a place brought into contact with the standing leg 4, when the stands are piled each other, forming an upper surface depression 8 such as a circular hole or a square hole at the center of the polished upper surface 5 of each standing leg 4, and forming a lower depression 9 on the polished lower surface 7 brought into contact with the standing leg 4 at a place corresponding to the upper surface depression 8. The upper surface depression 8 and the lower surface depression 9 are engaged with a ceramic engaging bar capable of being loosely inserted thereinto. |
