Verfahren zur Herstellung von Wolfram-Kupfer-Mischoxiden

A method for making a tungsten-copper composite oxide wherein an amount of an ammonium tungstate and an amount of an oxide or hydroxide of copper are combined without milling to form a mixture. The unmilled mixture is then dehydrated and fired at a temperature and for a time sufficient to form the t...
