PURPOSE:To exceedingly simplify and ensure sealing work by compression- molding and sealing all sealing materials into tablet shape other than mercury and rare gas that are sealed as a single substance. CONSTITUTION:When a metal-halide lamp is manufactured by sealing a number of metal halides containing mercury iodide (HgI2) and sodium iodide (Nal) together with mercury and rare gas in a luminous tube, all sealing materials other than mercury and rare gas that are sealed in a single substance can be compression-molded in tablet shape without using an organic or inorganic bonding agent by compression-molding them together within a specified pressure range, and a lamp that seals them is provided with exceedingly good and stable characteristics. The appropriate pressure under which the sealing materials containing mercury iodide and sodium iodide are compression-molded is 2 to 6 ton/ mm.<2>. |
