Au5 Ca1
semiconductor· Au5 Ca1
Au5Ca1 is an intermetallic compound in the gold-calcium system, representing a research-phase material rather than an established commercial alloy. This compound belongs to the family of precious metal intermetallics, which are of interest for their potential combination of thermal stability, corrosion resistance, and unique electronic properties. Gold-based intermetallics remain largely experimental; their practical adoption is limited by high material cost and processing challenges, making them candidates primarily for specialized high-performance applications where alternative materials prove inadequate.
