Scandium Metal

A: Scandium and yttrium are considered rare earth elements because they tend to occur in the same deposits as the lanthanides and exhibit similar chemical properties.

A: Scandium is a silvery-white transition metal, discovered in 1879 by Swedish chemist Lars Fredrik Nilson. It is extracted by removing it from other minerals and is relatively rare, with the majority of scandium being sourced from mines in China, Madagascar, and Russia. Distilled Scandium Metal is produced by heating scandium oxide in a vacuum until it vaporizes, then the vapor is condensed and collected. It is a very pure form of scandium, with a purity of 99.99%.

A: Refined scandium metal is a pure form of scandium that has undergone a refining process, removing impurities and making it suitable for use in high-tech applications. The refining process involves several stages, including acid digestion, solvent extraction, precipitation, and calcination, resulting in a scandium oxide compound. This compound is further reduced with aluminium to produce pure scandium metal.

A: Reduction Scandium Metal is an alloy made primarily of scandium and aluminum, with trace amounts of other elements such as magnesium and zirconium.

A: Refined scandium metal can also be used in other applications such as nuclear reactors, electronic components, and catalysts. Due to its unique properties, scandium has been identified as a critical material by the U.S. Department of Energy, and its demand is expected to increase in the coming years.

A: Distilled Scandium Metal is showing promise in the medical industry. It is a vital part of a new type of surgical laser that is currently in development, showing promise for cancer treatment, among other medical applications.

A: The distilled scandium get better quality than the reduced one. The refined scandium metal is dendritic like crystal of metallic lustre. However, the reduced one is broken irregular pieces.

A: Health effects of scandium:

Scandium has no biological role. Only trace amounts reach the food chain, so the average person's daily intake is less than 0.1 microgram.

Scadium is not toxic, although there have been suggestions that some of its compounds might be cancerogenic.

Scandium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Scandium can be a threat to the liver when it accumulates in the human body.

A: Effects of scandium on the environment:

Scandium is dumped in the environment in many different places, mainly by petrol-producing industries. It can also enter the environment when household equipment is thrown away. Scandium will gradually accumulate in soils and water soils and this will eventually lead to increasing concentrations in humans, animals and soil particles.

With water animals scandium causes damage to cell membranes, which has several negative influences on reproduction and on the functions of the nervous system.

A: Scandium can rarely be found in nature, as it occurs in very small amounts. Scandium is usually found only in two different kinds of ores. Thortveitite is the primary source of scandium with uranium mill tailings by-products also being an important source. World production amount to only 50 kg per year. There is no estimate of how much is potentially available.

Scandium is only the 50th most abundant element on hearth, it is distributed widely, occurring in trace quantities in over 800 minerals. The blue color of the aquamarine variety of beryl is thought to be caused by scandium.

Only about 3% of plants that were analysed for scandium shows its presence, and even those amounts were tiny, with vegetable having only 5 ppb although grass has 70 ppb.

A: Physical Properties of Scandium Metal:

• Scandium Metal is a delicate, light silvery-white metal that becomes slightly yellow or pink when exposed to air.
• It is almost as light as aluminum (low density), but has a significantly higher melting point.
• The taste and odor of Scandium are undetermined.
• 'Sc' is in a solid state at a room temperature.
• Scandium Metal is malleable and ductile.
• Sc is often regarded as a nonmagnetic element.
• This substance is not only unusual in terms of the element's valency (3), but it is also an excellent conductor of electricity for reasons that have yet to be discovered.
• Scandium Metal has a density of 2.99 grams per cubic centimeter. It has a melting point of 1541°C and a boiling point of 2836°C.
• Scandium Metal is the most effective known microalloying element for strengthening aluminum while simultaneously improving flexibility, heat and corrosion resistance, and weight.

A: Chemical Properties of Scandium:

• Scandium is similar to rare earth elements chemically.
• If scandium is exposed in air it will develop a layer of an oxide, which appears to be slightly yellow or pinkish in color.
• It weathers easily and dissolves slowly in most diluted acids.
• When scandium turnings are ignited in the air, it forms scandium oxide and emits a bright yellow flame.
