Abstract
Abstract When a ceramic member is fixed by brazing to a member made of metal such as stainless steel, weakness may be engendered in the ceramic near the brazed joint, Herein disclosed is a brazing method wherein the extent of any run-over of the brazing material onto the ceramic and/or the content of the titanium 'wetting' agent within the brazing material are carefully controlled to avoid such weakness.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
49 words
Method of brazing a metal member and a ceramic member together in which method the brazing material is kept within the confines of the joint between the two members and is not permitted to flow onto a portion of the ceramic which is not overlain by the metal member.
Claim 2
Dependent Claim
49 words
Method of brazing a metal member and a ceramic member together in which method the brazing material is kept within the confines of the joint between the two members and is not permitted to flow onto a portion of the ceramic which is not overlain by the metal member.
Claim 3
Independent Claim
70 words
A method of brazing a metal member and a ceramic member together in which method titanium is made available during the brazing to permit proper wetting of the ceramic but the amount of titanium so made available is kept sufficiently low to prevent substantial combining of excess titanium with said ceramic member, for example the titanium could be kept to around 5% or so of the brazing material by weight.
Claim 4
Independent Claim
70 words
A method of brazing a metal member and a ceramic member together in which method titanium is made available during the brazing to permit proper wetting of the ceramic but the amount of titanium so made available is kept sufficiently low to prevent substantial combining of excess titanium with said ceramic member, for example the titanium could be kept to around 5% or so of the brazing material by weight.
