Abstract (en)

[origin: WO9326021A1] A material for electrical contacts based on silver-tin oxide which contains tin oxide regions and further oxides and/or carbides in a matrix of silver or an alloy consisting mainly of silver. The further oxides and carbides are contained in the tin oxide regions and/or a transition region between them and the silver matrix. The proportion of the further oxides and carbides together amounts to 40 % wt. in relation to the quantity of tin oxide; the further oxides and carbides may be those of molybdenum, tungsten, bismuth, antimony, germanium, vanadium, copper or indium and, apart from a soluble component which may occur, the silver matrix is free of the further oxides and carbides.
