  • Sputtering target for producing optically transparent layers and method of manufacturing these targets
    Patent number: 4943362
    Abstract: Sputter targets of bismuth with 0.2 to 10% by weight manganese for producing optically transparent surface layers which reflect heat in combination with silver layers on panes of glass and of plastic achieve an improved resistance to UV in silver layers if the manganese is present in the form of the intermetallic compound BiMn in an even, finely dispersed distribution within the metallic bismuth matrix.
