Silver - Gold - Silicon

Introduction

[62Kup] 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 monovariant 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 [83Cas] and [83Has] throw doubt on the liquidus measurements reported by [62Kup] and the latter data are not accepted. [83Has...
