摘要:
A method for manufacturing an one-end closed ceramic double tube, which includes the steps of extruding a ceramic double tube having inner and outer cylinders, drying the ceramic double tube, forming at least one passage in one end of the inner cylinder of the ceramic double tube so as to communicate an inner space of the inner cylinder with a gap formed between the inner cylinder and the outer cylinder, sealing the one end of outer cylinder proximate the one end of the inner cylinder, and firing the ceramic double tube.
