Literature Data

[1962Kup] surveyed alloys at 10 mass% intervals throughout the ternary system using thermal analysis and metallography. Alloys were synthesized from Ag and Au with less than 0.01% impurities, and 99.99% Si by melting under a BaCl₂ flux in a high frequency induction furnace. As would be anticipated from the constituent binary systems the Ag-Au-Si system contains a ternary univariant eutectic curve originating at the Ag-Si binary eutectic and ending at the Au-Si binary eutectic. There is very little solubility of Si in the ternary Au_1–xAg_x solid solution or of Ag+Au in (Si). The data of [1983Cas] and [1983Has1] throw doubt on the liquidus measurements reported by [1962Kup] and the latter data are not accepted. [1990Has] studied 39 alloys by differential thermal analysis to produce ve...
