How to Clean Niobium Jewelry – Pretty Sensitive Ears

Anything less than 24k gold is an alloy, meaning that it is mixed with another metal. It is rare that a company will tell you what the alloyed metals are, and for that reason it is risky to purchase gold earrings if you have sensitive ears. The element was called columbium (symbol Cb) in the United States for about 100 years, while it was called niobium in Europe.

first: what is a metal allergy?

Niobium is rare and many refer to it as a semi-precious metal, if not a precious metal. It is an incredible material for jewelry because it is ultra-comfortable and hypoallergenic, once again because it is not mixed with the other metals that often induce allergic reactions for people. Furthermore, Niobium is non-reactive, meaning it does not create a tarnished surface.

That density is about equal to cartridge brass (8.5 gm/cc) and a little less than copper (8.9 gm/cc). It sells in bulk, wrought form for $6 to $12/oz., on average. But the fact that these deposits exist is good news for the country considering that its companies produced niobium-based alloys from imported niobium minerals, ferroniobium, and oxides. For now, nonetheless, the United States experiences import dependence particularly on Brazil, which supplied majority of its imports in niobium (75%), niobium oxide (86%), and niobium metal (91%). The name comes from Niobe, a figure in Greek mythology, who was Tantalus’ daughter.

Niobium description

Niobium is used in the production of high-temperature resistant alloys and special stainless steels, as well as high strength low alloy carbon steels. Its uses include sophisticated applications in the construction, automotive, aerospace, shipbuilding and oil and gas industries, such as the construction of bridges, steel structures for buildings and pipelines. Niobium is used with iron and other elements in stainless steel, high strength low alloy (HSLA) steels and other alloys. Niobium alloys are strong and are often used in pipeline construction, superalloys for jet engines and turbines, and heat resistant equipment.

An alloy is made by melting and mixing two or more metals. The mixture has properties different from those of the individual metals.

It is a small fraction of the metal used in jewelry manufacturing, but remains a viable choice for the designer. Indeed, niobium is a good metal investment because of its relatively stable prices as well as supply and demand, and its widespread use in industries. The metal can be isolated from tantalum, and prepared in several ways. Niobium was mined chifely as columbite, and is formerly known as colombium (Cb).

Niobium sits directly above tantalum in the periodic table, and they share very similar chemical properties. The metal takes on a bluish tinge when exposed to air at room temperature for extended periods.[35] Despite a high melting point in elemental form (2,468 °C), it has a lower density than other refractory metals.

Niobium description

The two elements have very similar properties and are difficult to separate. Finally, in 1844, German chemist Heinrich Rose ( ) showed that tantalum and columbium really were different from each other. Rose then suggested the name niobium for the new element. Niobe is the daughter of the god Tantalus, from whom the name tantalum comes. Niobium is used in arc-welding rods for stabilized grades of stainless steel.

Naming the element

Niobium description

It is completely inert inside the human body, making it a key ingredient in hypo-allergenic jewellery and heart pacemakers. Niobium does not react with water under normal conditions.

Why is niobium added to steel?

Niobium is named for the Greek goddess of tears, Niobe, who was the daughter of king Tantalus, according to the Royal Society of Chemistry, due to the element's similarities to tantalum (named for the king).

Niobium - Nb

Niobium description

Prices are soaring as China slashes export quotas and shows a willingness to use these materials as a political tool. Alarmed governments throughout the world are increasingly concerned about securing more reliable sources of critical materials for strategic and security purposes. But there are other rare minerals, outside of REEs, which are also crucial to economic and national security. Niobium, for example, is among the most critical, but has received little publicity.

Niobium description

Around 80% of niobium produced is used as a microalloying element in steels for the automotive industry, for oil and gas pipelines and in construction. Another significant end use of niobium is in the production of stainless steels in vehicle exhaust systems.

  • He discovered a new element in the ore and named it columbium after Columbia, the poetic name for America.
  • Major end uses for tantalum capacitors include portable telephones, pagers, personal computers, and automotive electronics.
  • Niobium compounds such as niobium carbide are used in cutting tools.
  • It is a soft, grey metal that is naturally found in the minerals pyrochlore and columbite.
  • It can be applied to an entire piece and then buffed to remove the high areas.

Is niobium a precious metal?

Niobium is a rare, soft, malleable, ductile, gray-white metal. It has a body-centered cubic crystalline structure and in its physical and chemical properties it resembles tantalum.

Niobium description

Anodizing produces a transparent oxide film on the surface that generates interference colors. It is essentially a patina-an oxide of niobium-and should be treated as such.

In the manufacture of super-alloys wherein niobium is mixed with cobalt, nickel, and iron that, in turn, are used in high-tech applications. These include gas turbines, turbo charger systems, jet engine parts, combustion equipment, and rocket sub-assemblies, among others. Notable examples of use include the air frame systems and nozzle for NASA’s spacecraft, such as Gemini and Apollo programs.

Physical properties

What is the cost of niobium?

Niobium–titanium. Niobium-titanium (Nb-Ti) is an alloy of niobium and titanium, used industrially as a type II superconductor wire for superconducting magnets, normally as Nb-Ti fibres in an aluminium or copper matrix. Its critical temperature is about 10 kelvins. In 1962, at Atomics International, T.

In 1809, William Hyde Wollaston made the wrong conclusion that columbium and tantalum were identical. In 1846, Heinrich Rose, a German chemist, discovered that ores of tantalum contained another element, niobium. Niobium is a rare, soft, malleable, ductile, gray-white metal. It has a body-centered cubic crystalline structure and in its physical and chemical properties it resembles tantalum. It must be placed in a protective atmosphere when processed at even moderate temperatures because it tends to react with oxygen, carbon, the halogens, nitrogen, and sulfur.

It is not used for medical implants because the metals can cause complications when left in the body. Some allotropes of elements show more pronounced metal, metalloid or non-metal behaviour than others.

What is niobium found in?

Niobium is a shiny, white, soft, and ductile metal, and takes on a bluish cast when exposed to air at room temperatures for a long time. The metal starts to oxidize in air at 200°C, and when processed at even moderate temperatures must be placed in a protective atmosphere.

Reaction of niobium with air

Niobium features many of the characteristics of precious metals. It is rare, difficult to refine, and highly resistant to chemical attack. It is malleable and hypoallergenic – and its price is above the current silver spot.

Niobium description

Is niobium good for sensitive ears?

Niobium. Niobium (Nb), chemical element, refractory metal of Group 5 (Vb) of the periodic table, used in alloys, tools and dies, and superconductive magnets. Niobium is closely associated with tantalum in ores and in properties.

Reaction of niobium with water

Niobium description

These compounds improve the grain refining, retardation of recrystallization, and precipitation hardening of the steel which increase the toughness, strength, formability, and weldability of the microalloyed steel. Niobium jewelry findings are good alternatives to precious metals. Findings made with niobium are hypoallergenic because they do not contain any nickel alloys, so they are safe for someone who is allergic to jewelry with nickel, copper, or other base metals and alloys.

Is nitrogen a metal?

Niobium Piercing Jewelry is Safe. Naturally nickel free, 99.9% pure niobium (Nb) is an excellent piercing jewelry material. It makes an especially great alternative for people who haven't been able to wear metal jewelry in their piercings because of nickel allergies or metal sensitivities.
