Production of High-Purity-Niobium Under Industrial Scale for Upcoming Linear Collider Projects R
Proceedings of PAC09, Vancouver, BC, Canada TU6PFP001 PRODUCTION OF HIGH-PURITY-NIOBIUM UNDER INDUSTRIAL SCALE FOR UPCOMING LINEAR COLLIDER PROJECTS R. Grill , PLANSEE SE, Reutte, Austria W. Simader, PLANSEE Metall GmbH, Reutte, Austria B. Spaniol, W. Feuring, W. C. Heraeus GmbH, Hanau, Germany Abstract material requirements. For RRR-Niobium sheet material Sheet, tubes and formed parts made of high-purity in December 2007 the PLANSEE Metall GmbH was Niobium with a high residual resistivity ratio (RRR- successful qualified as supplier for RRR-Niobium sheets Niobium) is the key component for future linear [4,5]. Both companies are now joining their competencies accelerators based on the superconducting radio- in the field of RRR-Niobium - from the electron beam frequency technology. To be prepared for large production melting, the processing into semi-finished products by use scale quantities, which are demanded for the upcoming of advanced manufacturing technologies and numerous projects like XFEL and ILC respectively, W. C. Heraeus analytical capabilities – to offer a complete product and GmbH (D) and PLANSEE Metall GmbH (A) joined their technology package for the accelerator industry. competencies in the field of RRR-Niobium. In 2007 the qualification procedure as material supplier for the XFEL MELTING project could be successfully finished and a complete Production of RRR-Niobium starts with standard product and technology package for products made of Niobium ingots melted by electron beam or electro-arc- RRR-Niobium was established. melting. The further refining is done by electron beam Based on the combination of the high expertise and melting where Niobium is purified in a vacuum at over long-term experience in electron beam melting of 2500 °C. -

TANTALUM-NIOBIUM INTERNATIONAL STUDY CENTER PRESIDENT'S LETTER RIO DE JANEIRO Dear Friends, OCTOBER 2007 The T.I.C plans to hold its Forty-eighth General Assembly on Monday October 22nd 2007 as part of a meeting from October 21 st to 24th 2007 in Rio de Janeiro, Brazil. Included in this meeting programme will be plant tours to Fluminense and CBMM. After the great success of our meeting in Innsbruck we expect this year's meeting also to attract a large number of members, guests and other interested parties to participate. Therefore I would like to encourage all of you to contribute to this meeting with suggestions for technical, commercial or more general papers to report on the progress our industry has made The Forty-eighth General Assembly meeting of the Tantalum and will be making. Niobium International Study Center will be held in Rio de Janeiro, Brazil, from October 21 st to 24th 2007. The technical sessions and social events will be held at the Hotel Sheraton Members of the Executive Committee, the Technical Promotions Barra, where delegates will also stay. The technical Officer and the Secretary General will meet in Brussels in April to presentations will cover a wide range of aspects of the industries review and outline the programme for the forthcoming General of both tantalum and niobium and feature Brazil in particular, in Assembly. I would encourage you all to provide your suggestions two half-day sessions to allow delegates a little spare time. on how we might improve our association and the service we provide to our members and would welcome your contributions The business and administration of the association will be carried to our deliberations. -

The challenges as they relate to Plansee and Ceratizit THE PLANSEE GROUP remain essentially the same: topics such as raw material When we speak of continuity in the Plansee supply, competitiveness, customer focus, skilled labor Group, we refer to continuity in terms of the company’s shortage and digitization will continue to keep us on owner ship, continuity with respect to the materials our toes. and products and, last but not least, continuity among the employees and in management. It also holds true for us that change is the only constant. We hope you enjoy reading this issue. At the same time, this kind of continuity is only possible through continual change – something that is BERNHARD SCHRETTER AND KARLHEINZ WEX happening more subtly at Plansee and Ceratizit. -
Plansee High Performance Materials: a Division of the Plansee Group Plansee Is the Expert for Refractory Metals – in Particular Molybdenum and Tungsten
Plansee High Performance Materials: A division of the Plansee Group Plansee is the expert for refractory metals – in particular molybdenum and tungsten. Two very special metals that are fundamentally different from other materials. Whether in the electronics industry, coating technology or high-temperature furnaces: Wherever traditional materials are stretched beyond their limits, Plansee's alloys and composites come into their own. Molybdenum and tungsten have exceptional heat resistance, making them dimensionally stable and extremely strong, even at high temperatures. Molybdenum has a melting point of 2,620 °C. And at 3,420 °C, tungsten has the highest melting point of all metals. Both metals have a very low vapor pressure and are particularly well suited for high- temperature applications in vacuum and protective gas atmospheres. Our metals combine excellent heat resistance with good electrical and thermal conductivity. And while some other metals such as copper are outstanding conductors, they cannot withstand high temperatures. In contrast, ceramic materials have good heat resistance but do not conduct electricity. Even at high temperatures, molybdenum and tungsten only expand very little. Their coeffi cient of thermal expansion is similar to that of semiconductor materials or sapphire. As a result, our customers typically use molybdenum and tungsten in combination with these materials. The density of tungsten is 60 percent higher than that of lead, which makes it a heavy element. It reliably shields against X-ray and gamma radiation. Our materials are also corrosion-resistant in contact with many substances – even at high temperatures. For example, when exposed to metal or glass melts. We further optimize their corrosion resistance by utilizing special coatings and alloy additives.
