There is described a brazing alloy having a first component comprising a source of molybdenum and a source of aluminum and a second component comprising boron, wherein a weight ratio of said second component to said first component is not greater than 1:20. The addition of boron results a substantially lower melting point than alloys employing molybdenum and aluminum alone. It is suitable for use in discharge vessels having a hollow bodies selected from the group of monocrystalline alumina, polycrystalline alumina and aluminum nitride; metallic electrode holders fitted into ends of the hollow body; and sealed thereto by a braze.
