| 内容： | A method and apparatus for forming a green ceramic arc tube for a metal halide lamp. A feedstock material (54) comprising ceramic and a binder is prepared and injected into an inner cavity (18) of a mold (12). The inner cavity 18 of the mold (12) has an inner surface (20) that corresponds to a desired outer shape of a body of the ceramic arc tube. A fluid (34) is injected into the feedstock material (54) to create a cavity (66) in the feedstock material (54) and to force the feedstock material (54) into contact with the inner surface (20) of the mold (12). The mold (12) is then separated from the formed ceramic green arc tube. |
