摘　　要：研制了7个重晶石矿石成分分析标准物质。其中，GSO-1为铁矿型重晶石，GSO-2、GSO-3为萤石型重晶石，GSO-4、GSO-5为石英型重晶石，GSO-6为硫化物型重晶石，GSO-7为黏土型重晶石。样品采用陶瓷衬里的球磨机加工，加工后样品粒度达到-0．074mm。采用X射线荧光光谱法检验了钡、铜、铅、锌、锆、铝、硅、铁和钙共9种元素的均匀性，并进行振动试验。8个实验室参加定值工作，提供了硫酸钡、氧化钡、三氧化硫和锶的7个标准值，全三氧化二铁的2个标准值，氟化钙的1个标准值及铜、铅、锌和水溶盐等标准值或参考值。2009年4月，7个样品已被国家质量监督检验检疫总局批准为国家一级标准物质，编号为GBW07811～GBW07817。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 BaSO,, 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.
