Patent ID: 8511535

Claim:
A method of brazing, said method comprising the steps of: a) providing a first part, said first part may be metallic or ceramic or a metallic composite or a ceramic composite; b) providing a second part, said second part may be metallic or ceramic or a metallic composite or a ceramic composite; c) providing a braze material between said first part and said second part, said braze material comprises: i. at least one metal oxide-noble metal mixture selected from 1. Ag—CuO, 2. Ag—V 2 O 5 , and 3. Pt—Nb 2 O 5 ; ii. and at least one additive selected from 1. at least one metal oxide selected from the group consisting of a. TiO 2 , b. YSZ, and c. Al 2 O 3 ; 2. and at least one metal selected from the group consisting of a. Al, and b. Pd, d) preparing the braze material by a high-energy ball milling process wherein the metal-oxide noble metal mixture is formed by high-energy ball milling a noble metal and a metal oxide to yield a metal oxide-noble metal compound; e) and heating said first part, said braze material and said second part in an oxidizing atmosphere.
