Technical field
The present invention relates to nickel (Ni) electrode sheet type multi-layer ceramic capacitance, particularly a kind ofly by electrolytic action, realize the method that the electric capacity internal electrode is successfully peeled off.
Background technology
Nickel (Ni) electrode sheet type multi-layer ceramic capacitance (MLCC) is to burn till preparation by high temperature after the ceramic membrane multiple-level stack of surface printing Ni electrode slurry.Burn till through high temperature, ceramic layer and electrode layer combine well by the NiO that the Ni oxidation forms, and conventional physico-chemical process is difficult to realize both separation.But in the research and production process, often need to confirm the microscopic pattern of electrode layer, therefore in the urgent need to a kind of practicable separation method.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of method of ceramic condenser interior nickel stripping electrode, can realize the nickel electrode layer of any designated layer and separating of ceramic layer.
A kind of method of ceramic condenser interior nickel stripping electrode, by grinding, the nickel electrode layer of ceramic crystal side is exposed, only have outer electrode part and the ceramic segment of getting rid of side by grinding, inner nickel electrode layer is exposed, just can reach the purpose of smooth electrolysis.Pour basic solution in container into, container is with not reacting with basic solution and nonconducting solid material is made.Ceramic crystal is placed in basic solution, and ceramic crystal can be immersed in basic solution fully, also can partly be immersed in basic solution, partly is immersed in the electrolysis effectiveness that the electrolysis effectiveness in basic solution is not immersed in basic solution fully good.One end of probe is connected with the positive pole of direct supply, and the other end contacts with the nickel electrode layer.Electrode wires one end is connected with the negative pole of direct supply, and the other end is immersed in basic solution.Electrode wires and metal probe are made with the solid metal material that can not react with basic solution.Open direct supply, after reasonable time, ceramic crystal is taken out from basic solution and drying.Because time of electrolysis is subject to crystal and peels off the impact of the factors such as voltage of NiO content, electrolysis in area, internal electrode, the time of electrolysis is uncertain.There is moisture between ceramic layer after electrolysis and nickel electrode layer, be subject to the molecular force impact and make ceramic layer and nickel electrode layer be difficult for separating, so need could separate ceramic layer and nickel electrode layer after drying.Again due to ceramic layer and nickel electrode layer distance each other very near, still have molecular force, need to use external force that the nickel electrode layer of ceramic crystal is separated with ceramic layer.The present invention utilizes simple electrolyzer, can realize the nickel electrode layer of any designated layer and peeling off of ceramic layer, has opened up a new way.The peeling off of ceramic layer and nickel electrode layer has benefited from rising at ceramic layer and nickel electrode interlayer the NiO of keying action, reduction reaction occurred: NiO
+H
2O
+ 2e
-=Ni
+ 2OH.
Preferably: the voltage of adjusting direct supply is the 1.5-5 volt.Although higher voltage can realize that the short period of time peels off, release surface is mostly clean not.Realize more easily that with relatively low voltage good layer peels off.
Preferably: basic solution is NaOH solution.
Preferably: the concentration of NaOH solution is the 0.5-5 mol/L.More be conducive to the electrolytic reaction of NiO in strong base solution.
Preferably: the making material of electrode wires is platinum.
Preferably: the making material of container is plastics or pottery.
Preferably: after ceramic crystal grinds, mirror polish is carried out in the side of ceramic crystal.The operation of polishing is to grind in order to eliminate the concavo-convex pattern that causes, and makes inner nickel electrode layer fully expose, facilitate electrolysis.
Preferably: after the side mirror mirror polish of ceramic crystal, use the side of Virahol or propyl alcohol or alcohol or toluene cleaning ceramic crystal.The purpose of cleaning after polishing is removal of contamination, keeps the internal electrode cleaning, facilitates electrolysis.
Beneficial effect: the present invention utilizes simple electrolyzer, can realize fast the nickel electrode layer of any designated layer and peeling off of ceramic layer, has opened up a new way.

Embodiment
The present invention is described further below in conjunction with accompanying drawing.
As shown in Figure 1, 2: at first by two sides 1 and two sides 3 to ceramic crystal 6, grind, make nickel electrode layer 2 except with contacted two faces of ceramic layer 4, all expose four sides of all the other of nickel electrode layer 2, and the abrasive surface mirror polish is processed, abrasive surface after polishing with an organic solvent cleans, and the organic solvent that uses can be Virahol, propyl alcohol, alcohol, toluene etc.
Instrument and material that electrolytic stripping uses are as follows: microscope, direct supply 8, reometer, electrode wires (platinum line) 10, conductive clip, probe 7, tweezers, container (plastics dielectric material vessel) 9, NaOH solution (sodium hydroxide solution) 11.Electrolysis step is as follows: 1. put into appropriate NaOH solution 11 as electrolyte solution in container (plastics dielectric material vessel) 9.The concentration of NaOH solution 11 is the 0.5-5 mol/L.One end of platinum line is immersed in NaOH solution 11.With tweezers, ceramic crystal 6 is immersed in NaOH solution 11 fully, and an one side 1 is placed up.The other end of platinum line is connected with the positive pole of direct supply 8, and conductive clip one end is connected with the negative pole of direct supply 8, and the other end is connected with probe 7.4. open direct supply 8, use reometer to measure electric current, set suitable voltage (1.5V～5.0V) and current value.5. make probe 7 aim at the nickel electrode layer 2 that will peel off at microscopically, through reasonable time, just can realize peeling off.In general the time of electrolysis is 30 seconds-300 seconds.6. close direct supply, take off and the cleaning ceramic crystal.7. after seasoning or heat drying, clamp 2 end faces 5 of ceramic crystal 6 with the substrate that posts double sticky tape, then along multilayer ceramic membrane stack face direction, separately get final product.Be that ceramic layer 4 with left side separates or the ceramic layer on right side 4 separates as for nickel electrode layer 2, generally speaking this probability is random, depends on probe 7 with nickel electrode layer 2 left side or right side contacts.
