Selenium 4n5n/6n Selenium Granule 99.999%
The Selenium 4n5n/6n Granule 99.999 % is a high‑purity selenium product offered by Sihcuan Hpm Co., Ltd in China. It conforms to the Se‑05 grade with a minimum purity of 99.999 % and carries CAS No 7782‑49‑2 and EC No 231‑957‑4. The granules are supplied in a nitrogen‑shielded environment to prevent oxidation, and the product is suitable for applications requiring stringent purity levels. All specifications follow recognised chemical industry standards for trace‑metal limits.
Typical selenium granules of this grade have a particle size range of 0.5 - 2 mm and a bulk density of 4.81 g/cm³, providing consistent flow in automated dosing systems. The melting point of 217 °C and boiling point of 684.9 °C ± 1.0 °C are standard thermal characteristics for elemental selenium. Impurities such as Ag, Al, Bi, Cd, Cu, Fe, Ga, In, Mg, Ni, Pb, Sb, Te and Tl are limited to below 10 ppm, matching common specifications for semiconductor and glass‑decolorisation use.
Sihcuan Hpm Co., Ltd packs the granules in nitrogen‑shielded double bags, typically 25 kg per bag, which are then placed inside 200 L steel drums for bulk export. Buyers should verify the applicable Incoterms, payment conditions and any required safety data sheets with the supplier, as these are not enumerated in the listing. The product is intended for manufacturers of photovoltaic cells, glass manufacturers, metallurgical processes and specialised chemical synthesis, where trace‑level purity is critical.

Prior to ordering, confirm that the selenium grade is indeed Se‑05 with a purity of 99.999 % and request the latest certificate of analysis and safety data sheet.
