ABSTRACT:
Disclosed is a method for forming alumina arc tubes of complex shapes. The method comprises molding alumina powders with different shrinkage rates into a green body. The green body is prefired to remove binders in the green body and then sintered. The resulting arc tube has an inner diameter that is smallest where the highest shrinkage powder was molded and an inner diameter that is greatest where the lowest shrinkage powder was used.
