ABSTRACT:
A ceramic arc tube assembly and a method for making a ceramic arc tube are described which simplify the manufacture of ceramic arc tubes by reducing the number of handling and heat treatments required to assemble arc tubes prior to the final sintering operation. In particular, the invention uses transient assembly buttons during intermediate assembly steps which are removed prior to the final sintering operation.
