The aluminium-nickel base contained conductor comprises the components of 1.0 to 8.0 wt% of aluminium powder, 1.0 to 8.0 wt% of boron powder, and the equilibrium amount of nickel powder, and the sum of all the components is equal to 100. The preparation method is a powder metallurgy method; in the method, materials are ground, mixed, pressed, sintered in vacuum, pulverized and fine ground after being blended; thereby, powders which can be prepared into conductive slurry and burnt into a nickel aluminum boron conductor in the air are obtained. The powders can be printed on a thermistor electrode substrate so as to manufacture a thermistor electrode, and the aging rate thereof meets the requirements.
Description
A kind of aluminium-nickel base contained conductor and preparation method.The present invention relates to a kind of aluminium-nickel base contained conductor and preparation method thereof, particularly a kind of aluminium-nickel base contained conductor that electrocondution slurry uses and preparation method thereof for preparing.
The present invention is the improvement invention of CN87100475.Ni-based conductor of CN87100475-kind boracic and preparation method thereof has been invented and has been added with a small amount of aluminium powder, boron-the aluminium of zinc powder-zinc-Ni-based conductor, providing with common metal replaces noble metal to prepare the approach of conductor, can make plasma display panel, also can make the thermistor electrode, reduce the conductor cost.But, on the one hand with boron-aluminium-zinc-when Ni-based conductor is made the thermistor electrode, aging coefficient higher (＞100%), desirable not enough, burn till the temperature requirement higher (900-110 ℃) of conductor on the other hand.
The objective of the invention is to improve the prescription of the Ni-based conductor of boracic, the aging coefficient reduction meets the requirements when using conductor to make the thermistor electrode; To reduce the temperature of burning till conductor in addition, reduce energy consumption.
