The experimental research of the superconducting microwave surface resistance with China’s niobium material (Nb2-l) at the liquid helium temperature is described. The measurement is made on X-band TE011 mode cavity. Unloaded Q0 value of 4.3×106 is achieved at a temperature of 4.2 K. The equivalent residual surface resistance is 1.8*10-4Ω.
