rhenium gasket surface after following the experiment.
Molybdenum differs from
rhenium in a marked ability to polymerization [26].
The [[alpha].sub.W/Re] separation factors shown in Figure 5 indicate that tungsten and
rhenium can be readily separated with 0.9% NaCl solutions at pH levels below 7.5.
The addition of
rhenium helps ensure the metals in the turbines keep their strength at very high temperatures.
Maybe accompanied by the reaction of interaction of the active carbide-forming (tungsten,
rhenium) elements with three carbon and the formation of carbide phases.
The Group acquired rare metal businesses such as molybdenum, selenium,
rhenium, tellurium, and bismuth from its controlling shareholder JCC, thus becoming one of the largest rare metal producers in China.

Topics include: new estimates of coal clarkes, fluorine and
rhenium in coal, prediction methods of ground movements, an assessment of total nitrogen emissions from coal combustion in China, heavy minerals and high-temperature mineralogy in coal, and energy sources and coal reserves in the Czech Republic at the beginning of the 21st century.
A modern, long-life mine at Pebble could produce one-quarter of America's domestic copper supply for 50-plus years, along with substantial volumes of gold, molybdenum and potentially other metals such as silver,
rhenium and palladium.
The company also has technologies and plant for recovering Indium and
Rhenium, having two facilities in Ontario, two in the U.S., and one in Germany.
Therefore, the chemistry of new super alloys was greatly influenced by reducing Cr content and increasing
rhenium (Re) content with a view to enhance the temperature capability.
