ABSTRACT:
A long alumina ceramic tube having good linearity is made by longitudinally joining shorter sintered alumina tubes at the ends thereof. The end of one shorter tube is ground and externally threaded. The end of another shorter sintered alumina tube is ground and internally threaded. The externally threaded end is then securely threaded into the internally threaded end. Additional tubes are similarly ground and threaded to attain the length of the long alumina ceramic tube.
