In 1906, William D. Coolidge filed a patent for rendering molybdenum ductile, leading to applications as a heating element for high-temperature furnaces and as a support for tungsten-filament light bulbs; oxide formation and degradation require that molybdenum be physically sealed or held in an inert gas.

Some nonmetals (black P, S, and Se) are brittle solids at room temperature (although each of these also have malleable, pliable or ductile allotropes). From left to right in the periodic table, the nonmetals can be divided into the reactive nonmetals and the noble gases. The reactive nonmetals near the metalloids show some incipient metallic ...

Molybdenum-based alloys are widely used, because they are cheaper than superior tungsten alloys. The most widely used alloy of molybdenum is the Titanium-Zirconium-Molybdenum alloy TZM, composed of 0.5% titanium and 0.08% of zirconium (with molybdenum being the rest). The alloy exhibits a higher creep resistance and strength at high ...
Molybdenum disulfide (or moly) is an inorganic compound composed of molybdenum and sulfur. Its chemical formula is MoS 2. The compound is classified as a transition metal dichalcogenide. It is a silvery black solid that occurs as the mineral molybdenite, the principal ore for molybdenum. [6] MoS 2 is relatively unreactive.
Control-rolled HSLA steels usually have higher strength and toughness, as well as lower ductile-brittle transition temperature [14] and ductile fracture properties. [13] Below are some common micro-alloyed elements used to improve the mechanical properties. Effect of micro-alloyed elements
It has a density of 5.323 g/cm 3 and is hard and brittle. [304] It is mostly unreactive at room temperature [n 33] but is slowly attacked by hot concentrated sulfuric or nitric acid. [306] Germanium also reacts with molten caustic soda to yield sodium germanate Na 2 GeO 3 and hydrogen gas. [307] It melts at 938 °C.
