A pyrotechnic device comprises a body of ignitable material (66). A pair of electrodes (44) and (52) provide electrical energy to heat and ignite the body of pyrotechnic material (66). The electrodes (44) and (52) extend through an electrical insulation housing (78). The electrical insulation housing (78) has surfaces defining a chamber (92) through which the electrodes (44) and (52) pass. A body (94) of a solid electromagnetically lossy, substantially gas impermeable material is positioned within the chamber (92). The lossy material comprises a vitreous ceramic matrix consisting essentially of about 5% to about 50% by weight of a multi-component glass binder and about 50% to about 95% by weight of an electromagnetically lossy ferromagnetic and/or ferroelectric filler. The body (94) of lossy material is fused to the surfaces defining the chamber (92) in the electrical insulation housing (78) and to the electrodes (44) and (52).
