Abstract

477,462. Sealing leading-in conductors into quartz. GENERAL ELECTRIC CO., Ltd., HARRIS, N. L., and RYDE, J. W. June 30, 1936, No. 18174. [Class 36] In a process of sealing through quartz a leading-in conductor consisting of a strip of an oxidizable refractory metal not more than 20Á thick, the strip is coated, before sealing, with a layer of a refractory non-oxidizable metal such as rhodium, the thickness of this layer being much less than that of the strip, and a quartz tube is collapsed on to the strip by means of heat applied externally without the complete evacuation of oxidizing gas, such as air, from the space between the tube and strip. The non-oxidizing layer is preferably formed upon the strip by the known process of distillation, by placing a clean strip in a vacuum adjacent to a tungsten helix enclosing a bead of rhodium and heating the tungsten by passing current therethrough until the rhodium evaporates and is deposited on the strip. Alternatively, the thin layer may be formed by the known process of cathodic sputtering, or by electroplating. In an example using a molybdenum strip 10Á thick, a layer of rhodium 0À75Á thick is provided. In sealing the strip within the tube, although complete removal of the air is not necessary, a partial removal aids the collapse of the tube by the external pressure. Alternatively mechanically applied pressure may be used alone in collapsing the tube. Specification 396,103, [Group XI], is referred to.
