The stationary furnace used for reduction has three temperature zones through which the boats loaded with tungsten tri oxide move before the oxide is converted to the metal. The loaded boats pass into the furnace countercurrent to the movement of hydrogen gas. Thus the gas in the highest temperature zone has the minimum moisture content, and the moisture content becomes maximum when the gas passes through the lowest temperature zone. This arrangement ensures the highest possible reduction efficiency.

No one tries to remember exact details of this or similar alloys. But the point of all these complicated additions of foreign atoms to the nickel is straightforward. It is (a) to have as many atoms in solid solution as possible (the cobalt the tungsten and the chromium) (b) to form stable, hard precipitates of compounds like Ni3Al, Ni3 Ii, MoC,... 

Tricarbonylchromium,221 -molybdenum,221 -tungsten,221 and-ruthenium222 complexes of 1H-azepine-l-carboxylatcs have been prepared by treating the azepines with tris(acetonitrile)tricar-bonylchromium(O), tricarbonyldiglymemolybdenum(O), tris(acetonitrile)tricarbonyltung-sten(O), and dodecacarbonylruthcnium(O), respectively. 

Antimony, arsenic, selenium, tellurium, iridium, iron, molybdenum, osmium, potassium, rhodium, tungsten (and when primed with charcoal,) aluminium, copper, lead, magnesium, silver, tin, zinc. Interaction of lithium or calcium with chlorine tri- or penta-fluorides is hypergolic and particularly energetic.
