高品位钼精矿(55%)标准样品的研制

DEVELOPMENT OF REFERENCE MATERIAL OF HIGH GRADE MOLYBDENUM CONCENTRATE(55%)

介绍了高品位钼精矿(55%)标准样品的成分设计、材料的选择、加工、均匀性初检、均匀性检验、稳定性检验以及标准值的确定。结果表明:钼精矿经负压蒸馏和筛分后得到的钼精矿原料,经均匀性和稳定性检验达到要求。本样品符合GB/15000-2008和YS/T409-2012标准的要求,已被全国标准样品技术委员会批准为国家级标准样品。

The development of reference material of high grade molybdenum concentrate(55%)was introduced on the aspect of composition design,material selecting,material processing,preliminary tests of homogeneity,homogeneity test,stability test and determination of standard values.The results show that the raw material of molybdenum concentrate obtained by negative pressure distillation and screening has been tested to meet the requirements of uniformity and stability.This sample conforms to the requirement of standard of GB/15000-2008 and YS/T409-2012,and has been approved as certified reference material(CRM)by National Standard Sample Technical Committee.
