In addition to iron some grades of copper, molybdenum, and tungsten is produced in this manner. Powders can be produced by a combination of vapor decomposition and condensation. The carbonyl processes for iron and nickel are the most common examples of this method. The metals react with carbon...
[36], copper[37]or graphite[38], have been investigated as coatings for the outer surface of the capillary, and these materials help establish electrical contact. In another approach, a platinum wire was directly inserted into the capillary to make a stable electrical contact[39]. More ...
