[0019] The cathode of the electrolytic cell adopts titanium oxide cathode rod, which is formed by mixing and sintering titanium dioxide fine powder and PVA binder in proportion. The oxide mass of each cathode rod is about 100g. Group. In the anode area, three rotating graphite anodes are connected in parallel in a manner corresponding to the cathode as electrolysis anodes. The distance between the cathode and the anode is 200mm, and the anode rod speed is set at 120rpm. Remove partitions. Using CaCl 2 molten salt, molten salt CaCl 2 The depth is 140mm, the temperature is controlled at 950°C, the flow rate of protective gas argon is set at 5L / min, the voltage of the electrolytic cell is 3.1V, and the electrolysis time is 36h. For the overall electrolysis process, see image 3 .
[0020] The shape of the product is basically unchanged, the density is high, the color is gray-black, and there is gray layering in the center part. After testing, it is mainly intermediate produc...
