Abstract
Complete chemical analyses of about 40 dental gold alloys were made as part of the investigation of their physical properties. These analyses required the determination of silver, gold, platinum, palladium, iridium, rhodium, copper, zinc, nickel, tin, manganese, iron, and magnesium. Methods as found in the literature for the determination of the above-named metals were modified so as to give accurate results when applied to alloys of this type. New methods were developed for the determination of tin and iridium. Many analyses of mixtures of known composition are given to show the degree of accuracy of the methods used. These methods are assembled in a detailed procedure for the complete analysis of dental gold alloys. The composition of 13 typical alloys is given in a table (page 409).
