A Zr-C sintered body is charged with H2 to form zirconium hydride within the body and such body is positioned in working association with a heating means within an electronic tube, such as a vidicon tube, which utilizes hydrogen as a supporting gas. During an operation of such tube, the sintered body is heated and releases an amount of H2 therefrom as a function of the temperature while the sintered body acts as a getter for any residual gases within the tube, other than H2, at elevated operating temperatures.
