Brief Introduction
Selenium is a non-metallic (or semi metallic) element (also known as quasi metal). It belongs to group 16 (via group) of the periodic table of elements and is located between sulfur and tellurium. Selenium has a variety of allotrope forms, including gray, red and black selenium. It mainly exists in sulfide ores of other metals and is obtained as a by-product (e.g. from anode sludge in electrolytic refining).
