Abstract

A method of providing a resistance to oxidation of Nickel at high temperatures by combining Ni powder with five percent Pt resinate, and heating the same to a temperature of 500° C. to 1300° C. Electro-conductive components serving as electrodes and the like comprise a Ni/Pt powder subjected to temperatures of between 500° C. and the respective melting points of Ni and Pt.

Claims (11)

1. An electronic component comprising:

a ceramic substrate;

an air-fireable end termination element resistant to oxidation in air of up to 1200° C., said element is comprised of a nickel and platinum alloyed product deposited onto the ceramic substrate, said alloyed product is formed from a combination of Ni powder and Pt resinate heat treated to a temperature between 1000° C. and a melting point of Ni in a reducing atmosphere, wherein Ni is presented in a proportion of at least 90% by weight with Pt making up the balance.

2. The electronic component of claim 1 , wherein the element has the proportion of Ni to Pt in approximately 95% to 5% by weight, respectively.

3. A capacitor comprising a ceramic substrate and an air-fireable conductor plate that is resistant to oxidation in air of up to 1200° C., said conductor plate is comprised of:

a nickel and platinum alloyed product, said alloyed product is heat treated to a temperature between 1000° C. and a melting point of Ni in a reducing atmosphere,

said alloyed product is formed from a combination of Ni powder and Pt resinate, wherein Ni is presented in a proportion of at least 90% by weight and Pt making up the balance.

4. The capacitor of claim 3 , wherein said alloyed product has the proportion of Ni to Pt in approximately 95% to 5% by weight, respectively.

5. An electronic component comprising an electrode screen printed onto a ceramic substrate, said electrode is an air-fireable conductor material that is resistant to oxidation in air of up to 1200° C., said conductor material is comprised of:

a nickel and platinum alloyed product, said alloyed product is heat treated to a temperature between 1000° C. and a melting point of Ni in a reducing atmosphere, said alloyed product is formed from a combination of Ni powder and Pt resinate, wherein Ni is presented in a proportion of at least 90% by weight with Pt making up the balance.

6. The electronic component of claim 5 , wherein the alloyed product has the proportion of Ni to Pt in approximately 95% to 5% by weight, respectively.
