Abstract

183,188. Maurer, J. March 18, 1921. Soldering.-A solder-paste for uniting precious and other metals consists of finely divided metals corresponding to the parts to be joined, oxides thereof, a reducing-means, a binding medium, and a flux. The binding-medium may consist of vaseline to assist the reducing-means, such as carbon, in reducing the oxides. The flux may consist of borax or boric acid. For soldering 20 to 22 carat gold, the paste may consist of four parts of flux, 0.3 parts of carbon, 0.5 parts of gold 833 fine, 0.83 parts of gold oxide, 0.12 parts of silver oxide, and 0.05 parts of copper oxide, together with 2 to 8 per cent of vaseline. For 18-carat gold, the gold used is 750 fine, the proportions of gold oxide, silver oxide, and copper oxide are respectively 0.75, 0.18, and 0.07 parts and the same proportions of other constituents as in the previous example. For 14-carat gold, 1 part of flux is used, 10 parts of gold 580 fine, and the same proportions of other constituents as for 18-carat gold. According to the Provisional Specification, the solder may also contain zinc, cadmium, &c.
