Abstract

Electrically conductive, optically transparent layers of tin oxide are deposited on an insulating base by thermal decomposition of vapours of tin tetra or dichloride in the presence of air, the thickness and distribution of the layer being controlled by the distribution and intensity of the heating to which the insulating body is subjected. As shown in Fig. 1, a glass bulb 1 is <PICT:0791667/III/1> <PICT:0791667/III/2> <PICT:0791667/III/3> <PICT:0791667/III/4> surrounded by an annular heat radiator 4 and SnCl4 vapour, preferably in a nitrogenous atmosphere is supplied through a nozzle 3 and removed by suction at 2. Air is drawn in around the nozzle 3. A uniform layer 5 corresponding to the area of the radiating body 4 is deposited on the bulb. According to Fig. 2, the bulb is heated by a heat radiator 4 and a mask 6 is interposed between the heater and the object to be coated whereby the deposit 5 is formed opposite the hole in the mask. The mask 6 may be cooled by liquids. In Fig. 3, a spiral heating filament enclosed in a tubular insulating body is passed around a tube 1 which is supplied by SnCl4 or SnCl2 from a nozzle 3 whereby a helical coating is formed on the inside wall of the tube 1. Similarly by arranging a heat radiating body of predetermined shape adjacent the object to be coated a predetermined distribution of layer thickness may be obtained. The body to be coated may be heated by di-electric heating as shown in Fig. 5 where the container 8 is fed with tin tetrachloride vapours through nozzle 3, and the body 1 to be coated is placed between two electrodes 7 supplied with high-frequency voltage. Depending on the shape of the electrodes or the relative movement of the body thereto, layers of different shape and thickness may be obtained. The arrangement may also be adapted to record variations in high-frequency energy by causing relative movement between the electrodes and the body to be coated whereby the variations are reproduced in the form of variations in the conductive layer. The conductive layers may be formed on the walls of electric discharge tubes to avoid wall charges or to obtain electrical screening, or to coat cathode-ray or tuning-indicator tubes, for the manufacture of helices or attenuator coatings for travelling wave tubes, for the manufacture of high power electrical resistors, particularly inside discharge tubes, to provide voltage supply to electrodes in electric discharge tubes and to establish electrical connections of elements of an electric circuit arranged on an insulating plate.
