Preparation of the cathode includes:shaping under the press of 40Mpa, sintering at 550℃for 1 hour and at 900℃for 8 hours and threading with molybdenum bar; Considering the literatures we choose CaCl2 as salt for preparation titanium. Pretreatment of salt is for 1 hour at 100℃and for 2 hours at 300℃. Partial pressure of oxygen which need lower than 5.11×10-7Pa to reduct titanium oxides and hygroscopic property of salt need a sealed equipment to electrolyse. And finally successfully designed a satisfied one and the results show that the equipment can be satisfied the requirment of the experiment. Flow of the inert gas is 1.5L/min, the voltage is 2.8 V, temperature is 850℃and time is 2 hours during pre-electrolysis. Flow of the inert gas is 0.2L/min, the voltage is 3.1 V, temperature is 900℃and time changes with the mass of TiO2 during electrolysis, namely the greater need the longer time; To eliminate influence of salt and other impurities, the products need to wash with distilled water and dilute chlorhydric acid , then wash with dilute hydrochloric acid under supersonic wave assistant. Finally, electrometical properties of the electrolysis of TiO2 is researched by cyclic voltammetry and chronoamperometry, and results show that there are two main reodox steps, namely from TiO2 to TiO and from TiO to Ti.

Why do people have the inspiration to make liquid seals ? First of all, no matter how tight you press the solid seals , they can't fill in those uneven places on the joint face, so gap always exists. But liquid seals can fill in the dent and present good sealing function. Meanwhile liquid seals have stickiness so they have adhesive force to metal adjoining planes, which is helpful to seal. Besides the stickiness of liquid seals is high so they will not move easily, which can ensure the leak tightness.

人们之所以会有液体密封件的灵感，首先是考虑到固体密封件无论怎样压紧，也不能完全填满接合面上的凹凸不平，在界面上总会存有间隙，而液态密封件却能将全部凹陷填平，呈现出良好的密封效果；同时，液态密封件具有一定的粘性，对金属接合面具有一定的粘附力，有利于密封，而且液态密封件的粘度是很高的，很难发生流动，从而进一步保证了密封性。
