ABSTRACT:
A long alumina ceramic tube having good linearity is made by longitudinally joining shorter alumina tubes at the ends thereof. The end of one shorter tube is ground to reduce wall thickness and is inserted into the end of another tube which has also been ground to reduce wall thickness. There are aligned peripheral grooves in the ground ends for the purpose of holding ceramic cement. The joined ends of the tubes are then fired at a high temperature to form a secure joint therebetween.
