Research abstract
Chromium is used in the hottest part of a jet engine as an alloying element is superalloys. None metallic impurities generally cause performance degradation and they have to be controlled. The existing chromiums used in supperalloys have C+S+O+ N+H>900 ppm according to specification. We are proposing to develop methods of refining that produce C+S+O+ N+H1400 C. Another method is using hydrogen at high temperature about 1400 C. This process uses many times the stoichiometric amount of hydrogen and furnace maintenance is high. Two of our methods are designed to use hydrogen in an innovative ways at higher temperatures while avoiding furnace problem. The third method described does not use hydrogen or carbon. Our aim is to produce high purity at a reasonable cost.
