However, in an aqueous solution in which the binder is dissolved in warm water,
The purpose is to produce a uniform slurry with stable viscosity by aging a nickel slurry made by dispersing carbonyl nickel powder for several tens of hours.

After being attached, it is dried and then sintered in a non-oxidizing gas atmosphere such as nitrogen or hydrogen.

。The present invention eliminates such conventional drawbacks in nickel slurry, and will be explained below with reference to Examples.

Carboxymethyl cellulose is poured into water heated to a temperature of , that is, hot water, and dissolved over several hours, and aged for more than ten hours at the same atmospheric temperature to swell this organic binder in water, and then stirred for several hours. Depending on the situation, viscosity,
It becomes possible to create an aqueous solution with stable properties.

ケルスラリーの性状を均一なものにし、芯体への塗着時
に最適な粘度、性状をもったスラリーにできる。The carbonyl nickel powder is mixed into the organic binder aqueous solution prepared in this manner, and then the nickel slurry is left standing for several tens of hours in a low-temperature atmosphere of 10 to 15°C to age the carbonyl nickel powder. This improves the compatibility between the nickel slurry and the aqueous organic binder solution, making the properties of the nickel slurry uniform, allowing the slurry to have the optimum viscosity and properties when applied to the core.

た。This method makes it possible to keep the viscosity of the nickel slurry constant, thereby eliminating the uneven thickness and coating weight of sintered substrates caused by conventional methods, and producing sintered substrates with stable quality and fewer appearance defects. It was possible to manufacture it.
