Is scandium harmful to humans?
Is scandium harmful to humans?
Health effects of scandium 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.
How much does scandium cost?
Scandium is a soft, light metal that might have applications in the aerospace industry. With a cost of $270 per gram ($122,500 per pound), scandium is too expensive for widespread use.
What scandium is used for?
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 is the 31st most abundant element on Earth, according to Periodic Table, with about 22 parts per million abundance by weight in Earth’s crust, according to Chemicool. Scandium is scattered thinly and has been found in over 800 minerals.
Why do we use scandium?
Is scandium rare?
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.
Is indium a rare earth?
In nature, indium is quite rare and nearly always found as a trace element in other minerals — particularly in zinc and lead — from which it is typically obtained as a byproduct. Indium has a low melting point for a metal: 313.9 degrees Fahrenheit (156.6 degrees Celsius).
Why scandium could be a huge opportunity?
Why Scandium Could be a Huge Opportunity . In its pure form, it has a silvery-white color. Moreover, it is always found in a combined state. In 1869, Mendeleev noticed that there was a gap in atomic weights between calcium (40) and titanium (48) and predicted there was an undiscovered element of intermediate atomic weight. For example
In a 2017 feasibility study for its Elk Creek niobium-scandium-titanium project, NioCorp Developments (TSXV: NB) pegs pricing for scandium oxide at US$3,500 per kilogram. Scandium International puts scandium oxide prices between $3,000 to over $5,000 , depending on product quality and purity, among other things. Oct 8 2019
Who discovered scandium and when?
Scandium was discovered in the minerals euxenite and gadolinite in Scandinavia. Lars Fredrik Nilson was the discoverer. He discovered scandium in 1879. The name scandium came from the place it was discovered- Scandinavia. Lars Fredrik Nilson created 2 grams of high purity scandium oxide.
What are the physical properties of scandium?
Physical properties. Scandium metal is a silvery-white solid with a slight pink or yellow tint when exposed to air. It has a melting point of 1,538°C (2,800°F) and a boiling point of about 2,700°C (4,900°F). Its density is 2.99 grams per cubic centimeter.
