Other Characteristics: Scandium metal is a soft metallic transition metal, it has a silvery-white appearance in its elemental form which oxidizes to yellow or pinkish when exposed to air. Scandium metal can react with water to produce hydrogen gas and dissolve in many acids.

Producing Methods:

Refined scandium metal is made from heating scandium fluoride (ScF3) with calcium metal. The reaction formula: 2ScF3+3Ca=3CaF2+2Sc. Refined scandium metal can be made into customized shape, like lumps pieces, ingot or other forms. Normally refined scandium cannot be directly used on end product. It need to get further process to remove impurities, especailly calcium. During the refining process, most calcium impurity will be removed from scandium metal.

Application:

Refined scandium shares the same properties with other level scandium metal. It is lightweight, but the melting point is much higher than aluminum. It could replace aluminum to make various aircraft. It is a raw material for high-melting alloy, for example Al-Sc alloy, Mg-Sc alloy, Sc-Ti alloy. It can apply to a space shuttle, rocket, and other high-end purposes. Except these, scandium is additive for steel, tungsten, and chromium alloy. The main application by volume is aluminum-scandium alloys for the aerospace industry and sports equipment, including sports (bikes, baseball bats, etc.) that rely on high-performance materials. It has been shown to reduce solidification cracking during the welding of high strength aluminum alloys. Scandium plays a vital role in the third-generation Illuminant that is a scandium sodium lamp. It is a kind of metal halide lamp that fills with sodium iodide and scandium iodide and, simultaneously, scandium and sodium foil in the lights. Scandium is used in household equipment such as color televisions, fluorescent lights, energy-saving lights, and glasses. Scandium metal is the best barrier metal in metal-insulator-semiconductor silicon photocell and solar cells. A growing application of scandium is on electric devicves. When doping AlN with Scandium (Sc) , it can significantly improve piezoelectric performance on 5G RF chips. Other uses of scandium is also developing such as fingerprint sensor, high SNR microphone,etc.

HAMM is a major producer of scandium metal in China. Our refined scandium metal can be used for making AlSc master alloy and producing higher quality distilled Sc metal. We can provide all kinds of scandium samples according to customer’s demands.

FAQs:

How did Lars Nilson discover scandium?

He applied heat to the nitrate and found that his sample contained small quantities of an unknown element with a low atomic weight. Spectral analysis showed 30 unique spectral lines, proving the existence of the new element. Nilson named the element scandium after the Latin word "Scanda"which stood for "Scandinavia". Sweden is part of Scandinavia.

What is scandium’s customs code?

Scandium metal’s customs code is 280530.

How much scandium is available?

High grade scandium oxide (scandia) product is scarce and typically not available in any significant commercial quantity. The world supply is estimated at 10-15 tonnes/year, although true production is impossible to determine and could be considerably higher. Production capability we believe is certainly higher, perhaps double this sales estimate. There is no orderly and transparent market for scandium oxide in its various grades, and sales are organized at agreed prices between buyers and sellers. Specialty minerals distributors can provide scandium oxide in small lots, suitable for research, but at premium prices.

How much scandium metal can you produce?

HAMM has a production capacity of 2000KG high purity scandium metal per year. Welcome to inquiry for our scandium products.

Is there any punish tariff for scandium exporting to other countries?

There is no punish tariff for exporting yet.

How is scandium refined?

Metallic scandium can be prepared by reducing the fluoride with calcium metal. It can also be prepared by electrolysing molten potassium, lithium and scandium chlorides, using electrodes of tungsten wire and molten zinc. Our refined scandium is made from Ca reduction scandium, after a series complex process, the refined scandium is made out.

How do you ensure your product’s quality?

Our producing process is very carefully operated, using highest purity raw material in the industry, anaylize every batch material in every procedure.

Can you customized some special element impurities in scandium metal?

Yes, we can control every element according to customer’s requiement.

Is scandium a rare metal?

Scandium and yttrium are considered rare earth elements since they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties. While named rare earths, they are in fact not that rare and are relatively abundant in the Earth's crust.

What is the importance of scandium?

Scandium is mainly used for research purposes. It has, however, great potential because it has almost as low a density as aluminium and a much higher melting point. An aluminium-scandium alloy has been used in Russian MIG fighter planes, high-end bicycle frames and baseball bats.

What is an interesting fact about scandium?

Scandium has a higher melting point than aluminum while having nearly the same density. Scandium is considered a rare-earth element because it is often found in rare-earth ores. It also shares many of the same chemical properties of other rare-earths. Scandium is the 35th most abundant element in the Earth's crust.

How does scandium improve the properties of aluminium alloy?

When added to aluminium, scandium substantially lowers the rate of recrystallization and associated grain-growth in weld heat-affected zones. Aluminium, being a face-centred-cubic metal, is not particularly subject to the strengthening effects of the decrease in grain diameter. However, the presence of fine dispersions of Al3Sc does increase strength by a small measure, much as any other precipitate system in aluminium alloys. It is added to aluminium alloys primarily to control that otherwise excessive grain growth in the heat-affected zone of weldable structural aluminium alloys, which gives two knock-on effects; greater strengthening via finer precipitation of other alloying elements and by reducing the precipitate-free zones that normally exist at the grain boundaries of age-hardening aluminium alloys.
