Seven certified reference materials of barite ores for chemical component analysis have been developed. GSO-1 is iron-barite, GSO-2 and GSO-3 are fluorite- barite, GSO-4 and GSO-5 are quartz- barite, GSO-6 is sulfide-barite and GSO-7 is clay-barite. Processed by ceramic-lined ball mill, the sample size is - 0.074 mm. The homogeneity test was performed by XRF analysis of Ba, Cu, Pb, Zn, Zr, Al, Si, Fe and Ca. The vibration test was also performed. 8 laboratories participated in the data certification and provided 7 standard values for BaSO4, BaO, SO3 and Sr, 2 standard values for TFe2O3, 1 standard value for CaF2 , as well as the standard or reference values for Cu, Pb, Zn and water-soluble salt. These seven standard reference barite ores were approved as the national primary reference materials (serial number is GBW 07811～GBW 07817) by General Administration of Quality Supervision, Inspection and Quarantine of China in April 2009.
