What Refractory Metals are commonly used in Vacuum Systems?

0 Comment

Refractory metal refers to the metals with a certain reserve and the melting point of which is higher than 1650 ℃. Refractory metals include tungsten, tantalum, molybdenum, niobium, hafnium, chromium, vanadium, zirconium and titanium. Rhenium also has a high melting point, but its reserves are too small, and most of it is used in high-temperature […]

What Can Molybdenum Compounds be used for?

0 Comment

Catalyst  Molybdenum base catalysts are widely used. When combined with cobalt and nickel, molybdenum is used in the petroleum industry because it can remove sulfur from organic sulfur compounds that are commonly found in crude oil. The application of molybdenum base catalysts will increase because of the further expansion of world crude oil supply and […]

Will Molybdenum Combine with Other Elements

0 Comment

Molybdenum. As shown in Table 2, the melting temperature of molybdenum is 695 degrees below that of tantalum. Because of its high melting point and relative abundance in the United States, it was the first of the refractory metals considered in this country for high-temperature structural applications. The primary use of molybdenum had been as […]

The List of Abundant Refractory Metals

0 Comment

Tungsten, tantalum, molybdenum, columbium, vanadium, and chromium may be classed as relatively abundant refractory metals; that is, Free World reserves of contained metal are over 100,000 tons for each metal. The first four show promise in a considerably higher temperature range than the last two, and sometimes the term “refractory metals” is used narrowly to […]

How Do We Use Molybdenum?

0 Comment

Molybdenum, whose chemical symbol is Mo, was first recognized as an element in 1778. Until at time, the mineral molybdenite—the most important source of molybdenum—was believed be a lead mineral because of its metallic gray color, greasy feel, and softness. In the late 19th century, French metallurgists discovered that molybdenum, when alloyed with steel in […]

Which Elements Have the Highest Melting Point

0 Comment

As we all know, melting point is the temperature at which substance converts from solid state to liquid state. Some of the metals show very high melting points at least 2,000 degrees Celsius, and they also have very high physical strength. These metals are named as refractory metals. Niobium, molybdenum, tantalum, tungsten and rhenium are […]
