Rare-metals is one series of our products. Quality and detail is our essence to devote to human health. The manufacturing and quality are licensed and supervised by KFO France. KFO France Co. Ltd. is biotech laboratories founded in France and China in 2001, KFO focuses on research and development of Metal dusts, Metallic powders, Metal Compounds.
The journal is dedicated to the publication and the dissemination of original research articles (and occasional invited reviews) in the field of rare metals to establish a platform of communication between engineers and scientists. Its coverage includes the metallurgy, processing, and determination of rare metals. This has been helped by its frothy price, and the fact that it is easy enough to pinpoint and extract from scrapped jet engines. By contrast, modern mobile phones, which may contain up to sixty useful and rare metals, are too small and fiddly for triage to be worth the effort. The journal also publishes papers on the application of rare metals in advanced materials, such as superconductors, semiconductors, composites, and ceramics.
In principle, aircraft do not need rhenium to stay aloft. However, as Thomas Graedel, an industrial ecologist at Yale University, and the lead author of the UNEP report, points out, the reason many modern products work so well is that they use materials whose properties are just so. "Without them, performance would suffer—slower computers, fuzzier medical images, heavier and slower aircraft." The second option is to recycle. Unlike over one-third of all metals, rhenium has actually seen a rise in recycling rates (although less than a quarter of the stuff found in new jet engines is second-hand). The upshot is that many valuable materials end up in landfills or are melted into new metallic alloys, wasting their unique properties.
