Abstract. This specification covers five grades of wrought niobium and niobium alloy strip, sheet, and plate. These are reactor grade unalloyed niobium (R04200-Type 1), commercial grade unalloyed niobium (R04210-Type 2), reactor grade niobium alloy containing 1% zirconium (R04251-Type 3), commercial grade niobium alloy containing 1% zirconium (R04261-Type 4), and RRR grade pure niobium ASTM B393-09e1 - Standard Specification for Niobium and 1.1.5 R04220-Type 5 RRR grade pure niobium. Note 1This grade of niobium is used in superconducting applications that require the ultra high purity. Because of the high purity the product is conducive to very large grains that can adversely affect formability.

In addition to the high RRR niobium, a lower grade niobium sample was also studied for comparison. The lower grade niobium was supplied by Rembar, and has a 99.99% purity level. The RRR value of the low-grade sample was not measured, but based on the purity level, it can be compared to reactor grade niobium, which has RRR values 30.

Abstract Past oxygen diffusion measurements were mostly conducted with commercial grade niobium. RRR measurement of furnace treated niobium samples showed the oxygen diffusion rate in high purity niobium can be
CBMM offers reactor grade, commercial grade, RRR superconducting grade and niobium zirconium in ingot form. Details. EU REACH. Access Reach Test Reports Safety Data Sheets Connect with an Expert Sales. Niobium Technology. Cbmm Logo. CBMM is the world's leading supplier of niobium products and technology. RRR characteristics of niobium along the welding Prototype cavities for the superconducting LINAC, named RAON, have been made and tested by the rare isotope science project (RISP) in South Korea. The cavities are quarter-wave resonators (QWRs), half-wave resonators (HWRs) and two types of single-spoke resonators (SSR1, SSR2). All cavities have been made of niobium (Nb) of high residual resistance ratio (RRR) grade. Superconducting Niobium(RRR>300) - tantalum-niobiumSuperconducting Niobium(RRR>300) production process. For high purity Niobium production, Nb 2 O 5 was usually reduced to crude Niobium first. Then the crude Niobium was purified by electron beam smelting, followed by rolling, pickling, annealing and polishing process. After these processes above, high purity Niobium materials (RRR>300) can be
