Definitions
- graphite is to be understood herein to mean not only carbon crystallized in the form of graphite, but also a material consisting in part of non-crystallized carbon, as may be the case, for example, with commercial products referred to as electrographite.
- connections between graphite and certain metals may be established with the use of molten metal.
- Such connections usually have the above-mentioned disadvantages not at all or to a reduced extent only.
- connections may be obtained with the use of indium or an indium alloy. It is also known, for example, that graphite bodies may be connected to aluminum with the use of tin. Such connections have the disadvantage, however, that indium, in dium alloys and tin have comparatively low melting points.
- connection between graphite and metals with the use of oxides.
- a connection between iron and graphite may be obtained by heating in an oxidizing atmosphere, the connection being established by ferric oxide produced.
- ferric oxide produced Such a connection has a comparatively low mechanical strength.
- An object of the invention is to overcome the abovementioned disadvantages.
- articles of graphite are connected together or to articles of other materials by soldering with an alloy of gold having a content of tantalum and/or columbium of at least 1% by weight in vacuo or in an atmosphere of inert rare gas.
- Alloys having a lower content of tantalum and/or columbium provide insufficient wetting of the surfaces to be connected.
- Alloys having a tantalum content up to by weight and those having a columbium content up to 10% by weight have melting points lower than 1,300 C. and are 3,195,536 Patented July 27, 1965 ductile.
- the alloys may therefore readily be formed into wire or foil, which may be advantageous in soldering.
- alloys having a tantalum content from 5% to 10% by weight.
- the content of columbium is preferably chosen not higher than about 5% by weight.
- Alloys of gold with tantalum and/or columbium provide very good wetting of surfaces of graphite articles in soldering.
- other materials of the most widely varying kinds such as quartz, ceramics and metals, more particularly molybdenum and tungsten, are properly wetted.
- a graphite rod of 6 mms. in diameter is soldered, at one end, to a tungsten plate with an alloy consisting of 97% by weight of gold and 3% by weight of columbium.
- the solder in the form of a circular piece of foil of 10 mms. in diameter and microns thick is brought between the rod and the plate.
- heating takes place to about 1,300 C. in an atmosphere of argon.
- a graphite tube and a ceramic tube of alumina having the same dimensions as specified in Example 1, are connected together with the use of an alloy consisting of 97% by weight of gold and 3% by weight of tantalum.
- the tubes are ground at one of their ends to have a conical shape so as to fit into each other over a length of a few mms.
- a strip of foil 150. microns thick of the said alloy is provided between the ends of the tubes, whereupon heating takes place in vacuo to about l,300 C.
- a method of joining graphite articles to other articles selected from the group consisting of graphite, quartz, ceramics and metals comprising applying an alloy consisting essentially of gold and a member selected from the group consisting of tantalum in an amount of from 1% to 25% by weight and columbium in an amount of from 1% to 10% by weight in contact with opposing surfaces of said articles and melting said alloy in an inert atmosphere.
- the alloy is an alloy of gold and from 1% to 25 by weight of tantalum.
- the alloy is an alloy of gold and from 1% to 10% by weight of columbium.
- the alloy is an alloy of gold and from 1% to 5% by weight of columbium.
