This edition features the 2021 Ekeberg Prize-winning paper on tantalum machining challenges. It explores cutting mechanics, sinuous flow, and a novel mechanochemical effect using marker ink to improve cutting efficiency.
Bulletin 188 highlights the shortlisted research for the 2022 Ekeberg Prize, including novel work in tantalum bonding, thin film testing, and additive manufacturing. Also featured are updates on CERN’s use
Developed by the World Customs Organization (WCO), this is a six-digit figure for describing internationally traded goods. Individual countries may further extend this code with an additional two or four
Niobium consumption is dominated by its use as additive to high strength low alloy steel and stainless steel for oil and gas pipelines, car and truck bodies, architectural requirements, tool
Two separate processing schemes are utilized for niobium production. Those companies that mine pyrochlore convert the niobium oxide units into HSLA ferroniobium through the aluminothermic reduction process or by reduction
The extraction and refining of tantalum, including its separation from niobium in various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric
