Abstract
1,103,523. Spark apparatus; electrode materials. SIEMENS - SCHUCKERTWERK A.G. 11 Feb., 1966 [16 Feb., 1965], No. 6256/66. Heading HID. [Also in Division H3] The composition and disposition of metallic main electrodes 5, 6 and an insulator 2 in a spark gap triggered by a discharge along a surface of semi-conductor material are such that in operation any metal vaporized from the electrodes combines chemically with the insulating material to produce a material which is electrically substantially non-conductive, the insulator 2 forming part of a chamber which is filled with gas at such a low pressure that the device is operable at a point on the lefthand branch of the Paschen curve. The demountable device shown is filled with air at a pressure of 0.03 mm. Hg. and is held together by atmospheric pressure and optionally by clamping devices (not shown). A cathode 3 and anode 4 have tungsten-copper disc discharge surfaces 6 and 5. The insulator 2 is of steatite and has flanges 9 and 10 which protect sealing rings 7 and 8 from the discharge. The trigger device 12 has a central electrode connected to a pulse generator and having a tungsten-copper tip from which a discharge passes across an annular surface of zinccadmium oxide to a tungsten-copper ring. An eccentric exhaust pipe 11 communicates with a vacuum pump and a gas inlet and pressuremeasuring device. An insulator 15 lengthens the leakage path between a cathode connecting flange 13 and the anode 4. A modified device (Fig. 5, not shown) has a centrally disposed exhaust pipe 11 and two eccentrically disposed trigger devices 12. The metal of the main electrodes 5, 6 may be sintered and the main and trigger electrodes are preferably formed by an infiltrated composite metal comprising a skeleton of high melting-point metal, e.g. tungsten, rhenium or molybdenum, all the pores of which, or only those at the surface, are infiltrated by a second metal which is a good conductor of heat, e.g. copper or silver. Alternative materials for the insulator 2 are porcelain and eucryptite-containing ceramics. An alternative material for the semi-conductive trigger surface is silicon carbide.
