How Much Do You Know About Tantalum Niobium? The atomic sequences of tantalum (Ta) and niobium (Nb) are 73 and 41 respectively, both of which are located in the area of the excessive element of VB. They are often symbiotic in nature and are important refractory metals. They have many excellent properties, such as high […]
What Are the Uses of Tantalum and Its Alloys? Tantalum is the third most refractory metal, with a melting point of 2980℃, only after tungsten and rhenium. Besides, tantalum also has other excellent properties like low vapor pressure, good cold workability, high chemical stability, strong resistance to liquid metal corrosion, and large dielectric constant of […]

Will Molybdenum Combine with Other Elements? 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 […]

Why Tantalum Is Important? Tantalum occurs in columbium ores. As the demand for columbium increases, increasing amounts of tantalum concentrates become available. After a difficult and complex separation and reduction process, both metals are obtained in the form of powder. The powder is pressed in dies to form bars which are vacuum sintered by passing […]
The List Of Abundant Refractory Metals 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 […]
The Metal that Doesn’t Fear Aqua Regia—Tantalum Corrosion is the damage or qualitative change of material under the influence of the environment. The corrosion of metal and alloy is mainly caused by chemical or electrochemical damage. Common corrosion-resistant metals are austenitic stainless steel, Hastelloy, Monel alloy, titanium and titanium alloy, platinum, gold, rhodium, and other […]
Which Elements Have the Highest Melting Point? As we all know, the 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. […]
