preparation example Construction
[0035] The present invention firstly provides a kind of preparation method of rare earth electrode, and this method comprises:
[0036] Step 1: Mix nickel powder, titanium powder, quartz, calcium carbonate, magnesium carbonate, clay, pore-forming agent and binder, ball mill, granulate, and screen to obtain powder;
[0037] Step 2: Injection molding the powder obtained in Step 1, and sintering the formed product to obtain an electrode matrix;
[0038] Step 3: mixing cesium carbonate solution, lanthanum nitrate solution, strontium nitrate solution and manganese nitrate solution, and then adding a chelating agent and a dispersing agent to react to obtain a gel;
[0039] Step 4: Soak the electrode matrix obtained in Step 2 into the gel obtained in Step 3, and then put it into a hydrogen furnace for reaction to obtain a rare earth electrode.
[0040] According to the present invention, nickel powder, titanium powder, quartz, calcium carbonate, magnesium carbonate, clay, pore-formi...
Embodiment 1
[0048] 10g of nickel powder, 10g of titanium powder, 38g of quartz, 5g of calcium carbonate, 5g of magnesium carbonate, 5g of clay, 20g of graphite powder and 7g of polyvinyl alcohol were mixed, then ball milled, granulated, and screened to obtain a 150-mesh powder;
[0049] Put the above-obtained powder into the green body, realize molding with injection mold, the molding pressure is 6.5Mpa, and sinter the molded product at 400°C for 12h to obtain the electrode matrix;
[0050] Dissolve cesium carbonate with a purity of 95% in deionized water containing 15% ethanol to form a cesium carbonate solution, then mix 1000ml cesium carbonate solution, 25ml6% lanthanum nitrate solution, 25ml1.5% strontium nitrate solution and 25ml2.8% nitric acid The manganese solution was mixed, then 25ml of citric acid and 25ml of n-butanol were added, and the reaction was carried out at 80°C for 2 hours. The obtained product was evaporated and concentrated to form a sol, and then the sol was evapora...
