Formulations/Preparations: •four grades of selenium are available. there is the commercial or refined grade, which contains >99.5 wt% selenium and various impurities, usually <0.2 wt% tellurium, <0.1 wt% iron, <0.005 wt% lead, and <0.005 wt% copper. this grade is sold mainly as 75-mm (200-mesh) powder as well as in smaller quantities of coarser size and as lump. a second, more select pigment grade has a purity of 99.7%. the third grade, high purity selenium, contains 99.999 wt% of selenium, although this figure of purity is obtained by difference and not by a direct determination. this grade is sold usually in shotted form but also in small amounts as a powder. some users have their own specifications, which reflect a particular application of selenium. the fourth grade, called ultrahigh purity selenium, is claimed to contain 99.999-99.9999 wt% selenium. •available as pellets or powder. •grades: commercial (powder or lumps), high-purity up to 99.999%. •most domestic selenium was produced as commercial-grade metal, averaging a minimum of 99.5% selenium and available in various forms, including shot, lump, or powder, or as pigment-grade powder having a minimum 99.8% selenium content.
