Precious metal-based amorphous alloy having plastic processability and useful as bulk material for electrolysis anodes |
摘要 |
<p>The object of the invention is to provide an excellent electrode having an excellent corrosion resistance and long service life even in a severe oxidization 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 a general formula of compositions expressed by NM100-a-b-cNiaCubPc, wherein NM comprises one or two precious metal elements selected from Pd and Pt; a, b and c being atomic percent, satisfy that 30 </= a+b </= 45,3 </= b/a </= 7, and 18 </= c </= 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.</p> |
