摘　　要：Niobium is widely used in SRF （Superconducting Radio Frequency） cavities due to its excellent superconductivity and workability. With the continuous development of technology, higher demands of material are raised. One of the key issues is that RRR （Residual Resistance Ratio） of the Nb material should be more than 300, which requires that the Nb ingot have even higher RRR. This article introduces the development and the experimental results of high purity niobium in OTIC in Ningxia （Ningxia Orient Tantalum Industry Co. Ltd.）, and the test results of the single cell TESLA （Tera Electron volt energy Superconducting Linear Accelerator） shaped cavity manufactured by Peking University using Nb material from OTIC.Niobium is widely used in SRF （Superconducting Radio Frequency） cavities due to its excellent superconductivity and workability.
