Molybdenum is a transition metal (refers to the "D" block of the periodic table), or more strictly, "a transition metal as "an element whose atom has an incomplete d sub-shell, or which can give rise to cations with an incomplete d sub-shell". (source Wikipedia). In its pure form, molybdenum metal is a soft, silvery white metal which has one of the highest melting points of all elements. The melting point of molybdenum is 2,623°C (4,753 °F), which is 2,000°F higher than the melting point of steel. It is also 1,000°F higher than the melting point of most rocks. Though it has the fifth highest melting point of all of the elements, it has the lowest coefficient of thermal expansion, making it a highly sought after component in high temperature applications.
