Abstract
An electrode having an excellent corrosion resistance and long service life even in a severe corrosive environment such as in NaCl solutions for anode electrolysis in which chlorine gas or the like is produced at a high potential from the alloy surface. The electrode of the invention is provided using a precious metal-based amorphous alloy which has a good plasticity processibility and is applicable to a large-sized component. The object is implemented by provision of an electrode material for anode electrolysis which utilizes a precious metal-based amorphous alloy which satisfies the general formula NM.sub.100-a-b-c Ni.sub.a Cu.sub.b P.sub.c wherein NM comprises one or two precious metal elements selected from Pd and Pt; a, b and c being atomic percent, satisfy that 30.ltoreq.a+b.ltoreq.45,3.ltoreq.b/a.ltoreq.7, and 18.ltoreq.c.ltoreq.25, respectively; Pt is contained from 10 to 30 atom percent (at. %); and wherein a temperature width .DELTA.Tx in the supercooled liquid region (.DELTA.Tx=Tx-Tg) has a width of 70 K or more.
