Abstract
A radioluscent window structure comprised of an aluminum pane gas-impermeably sealed to a metal frame, as on a vacuum tube, is produced by applying a silver layer on the outer frame edges and on the outer pane edges, positioning the resultant metal frame and pane so that the silver layers thereof are in contact with one another and subjecting the resulting structure to diffusion welding conditions sufficient to achieve a gas-impermeable seal between the frame and the pane.
