Production Process of Scandium Oxide

Posted on by adminLeave a comment
What’s Scandium Oxide powder? The most significant product in scandium products is the Scandium Oxide. The physical and chemical characteristics of Scandium oxide are identical to that of rare earths oxides. Therefore, production processes are very similar. Sc2O3 may produce metal scandium and other scandium alloys under certain environmental conditions. Scandium oxide has many uses in aerospace, aluminum alloys, electric light source and lasers, ceramics, activaters, catalysts, ceramics, and other areas.

Scandium Resources in Nature

Scandium is found in approximately 800 different minerals. There are very few scandium-containing mineral species, mostly due to the interaction with other minerals. You can find many minerals that are scandium-containing, including wolframite ores, ilmenite and rare earth ores, vanadium-titanium magneticite, rare Earth iron ore, manganese depleted ores, rare earth ores, ilmenite and bauxite. The mines contain the highest amount of scandium.

Materials Used in the Production of Scandium Oxide Powder

Scandium oxide raw materials are mostly scandium-containing liquids, such as waste residue or soot from metallurgy. They also include scandium concentrate that has been obtained following the beneficiation vanadium–titanium magite.

1. The majority of the tungsten-extracted waste is contaminated with scandium. Scandium oxide 0.05%) can be found in the original ore of wolframite. Scandium oxide is 150 to 600 g/t after the extraction. Pretreatment involves dissolving the waste in hydrochloric acids. The resulting ScCl3 solution then becomes the raw material to obtain scandium oxide. 2. A waste liquid containing scandium (mainly after the extraction of titanium form ilmenite) is considered to be a “scadium-containing” fluid. Scandium oxide 15-20g/m3 is the primary raw material to extract scandium dioxide from ilmenite. 3. Scandium-containing soot is mainly the soot from sponge titanium’s chlorination. Pretreatment of the soot results in acid-dissolved scandium liquid, which is used as raw material to extract scandium oxide. 4. Scandium concentrate, mainly from scandium magnetite beneficiation. Sc 27g/t of vanadium magnetite is present, and Sc 112-114g/t after beneficiation. ScCl3 is obtained by dissolving the scandium concentrate in hydrochloric acids. It is used as raw material to extract scandium dioxide.

About Scandium Nitride ScN Powder:
Scandium nitride (ScN) is an III-V type indirect bandgap semiconductor. It’s made up of scandium ions and nitrogen ions. The crystal structure of rock salt can be grown on tungsten foil by sublimation and condensation. The lattice constant of rock salt is 0.451 nm, the indirect bandgap is 0.9 eV, and the direct bandgap is 2 ~ 2.4 eV. These crystals can be synthesized by indium and scandium melt dissolved nitrogen, magnetron sputtering, MBE, HVPE and other deposition methods.
Scandium nitriding (ScN) is a rock salt structure semiconductor, which is a semiconductor element of epitaxial metal/semiconductor superlattices and has attracted much attention due to its potential application in thermoelectric conversion devices.
Scandium nitride is a transition metal nitride semiconductor with high hardness, high melting point and high electron mobility and other remarkable properties. This material has a wide range of potential applications in new optical, electrical and piezoelectric devices. Rmcplant is a trusted global Scandium Nitride ScN Powder supplier. Feel free to send an inquiry about the latest price of Scandium Nitride at any time.

How is Scandium Nitride ScN Powder Produced?
Under the condition of a high temperature and low-pressure system and with the aid of plasma, the high-purity rare-earth scandium metal reacts directly with nitrogen to produce blue-green powders with a metallic luster.
 
Applications of Scandium Nitride ScN Powder :
Due to the good lattice match between the two crystal structures, ScN thin films improve the performance of gallium nitride devices, which has attracted special attention. In addition, ScN has good thermoelectric properties. In such applications, however, it is necessary to reduce its high thermal conductivity

Scandium — The Aristocrat of Rare Earth Family

Posted on by adminLeave a comment
Noble metal This is scandium’s most central member of the rare earth elements family. The actual worldwide production of scandium in 2016 was less than one ton. That means every person who is more than seven thousand can obtain 1 gram. The availability of scandium, which is rarer than rare earth, rare-earth and expensive than gold, makes it more difficult to find. Independent minerals have been found only in Madagascar and Europe, with no industrial application. Nelson in Sweden, a Swedish chemical chemist, discovered Scandium during 1879 in the Siyllium–ytrium and Heilinite Gold mines of Scandinavia. Scandium can often be found dispersed within minerals with other elements. This makes it impossible for the naked eye to locate scandium. Scandium is difficult to extract. To extract scandium metal successfully for the first time, it was half a century after its discovery.

Scandium metal prices

Most scandium products sold on international markets are scandium metal scandium or scandium dioxide. Price is determined by the level of purity. 2017 saw the cost of 99.99% pure scanningdium oxide at $4,600 per kg. However, the price for distilled metal scandium reached $226,000/kg. This is five times more than the gold price ($44,445/kg). Scandium prices have fluctuated and dropped significantly between 1990-2006. Let’s take the distilled metallic scandium for an example. Scandium’s price was high in 1993 at $372,000/kg. In 2005 it dropped to $162,500/kg. The prices of scandium have increased since 2006. In the rare Earth family, it is much more expensive that other light-rare earths. It also costs more than the rare heavy metals terbium, dysprosium, and terbium. When rare earths prices rose, for instance, scandium oxide (91%) in China was $26,000/kg. This is more than double the prices for europium (2,000 yuan/kg), terbiumoxid (10,200yuan/kg), or any other rare earth oxides. Rmcplant (aka. Rmcplant is an advanced material.
