Document Type and Number:
Japanese Patent JP2877681
Kind Code:
B2
Abstract:
A method for producing a ceramic long body has the steps of: hanging a ceramic non-sintered body having a long shape inside a sheath so that said ceramic non-sintered body does not touch the sheath; firing the ceramic body at a temperature at which the ceramic body sinters until the sintering is completed to obtain a sintered ceramic body; hanging the sintered ceramic body upside down; and firing the sintered ceramic body again at a temperature at which the ceramic body sinters. The method gives a ceramic long body having little deformation, and the present invention can be suitably employed as a method for producing, for example, a heat transmitting tube a heat exchanger of a shell-and-tube type.
