Abstract

Sulphur-containing gold, used for producing semi-conductor devices (see Division H1) is produced by adding elemental sulphur or a sulphide, such as of antimony, lead or thallium, to liquid gold, and immediately thereafter cooling the gold at a rate greater than 50 DEG C./sec. to a temperature below its melting point, e.g. to below 200 DEG C. and preferably to room temperature. Further alloying additions, e.g. boron, antimony, arsenic or bismuth, are preferably admixed with the gold before adding the sulphur. The process may be carried out, as shown in Fig. 1, in a quartz or glass vessel 2 connected by tube 3 to a chamber which supplies, preferably under superatmospheric pressure, a protective gas such as argon, helium or <PICT:0948217/C3/1> carbon monoxide to keep air from the liquid gold 5 in a quartz or graphite crucible 4 heated by induction, radiation or (as shown) a resistance heater 6, e.g. to 1150 DEG C. The supply of sulphur, e.g. pressed gold and sulphur, or a sulphide, is preferably wrapped in gold foil to form a pellet 11 held on the end of a rotatable rod 9. After addition, the gold is poured by rotating the crucible into a cooling vessel 12. Specification 866,376 is referred to.
