The maximum concentrations measured foreach impurity are as follows: Sr 4 mg/g (4 000 ppm) Ca 500 μg/g (500 ppm) K 200 μg/g (200 ppm) Na, Mg, Al, Fe, Nb 100 μg/g (100 ppm)The minimum concentration or detection limits are from 1 μg/g to 5 μg/g (1 ppm to 5 ppm).【中国标准分类号】: Q32【国际标准分类号】: 81_060_30【页数】: 10P.;A4【正文语种】: 英语
