Selenium is a chemical element with symbol Se and atomic number 34. It is a nonmetal with properties that are intermediate between those of its periodic table column djacent chalcogen elements sulfur and tellurium. It rarely occurs in its elemental state in ature, or as pure ore compounds. Selenium is found impurely in metal sulfide ores, here it partially replaces the sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores, most often during copper production.
Usage: It is mainly used in the preparation of the material of the selenium drum, photoelectric material, electrostatic photogragh and other materials of optical instrument.
Packing: It is packed with dacron film, then covered with a sealed plastic film bag.
