Facts about Scandium Metal
Essential Facts about Scandium
Scandium, symbolized as Sc, holds the 21st position on the periodic table and is categorized as a transition metal. Rare and valuable, scandium is known for its bright silvery appearance and remarkable properties that make it useful in a variety of high-tech applications. Despite its scarcity, scandium plays a crucial role in modern materials science, particularly in alloys used in aerospace and sporting goods. As one of the elements first predicted by Dmitry Mendeleyev, its discovery and subsequent uses have highlighted the predictive power of the periodic table, showcasing the ongoing relevance of fundamental chemistry in technological advancements.
Historical Facts: Discovery of Scandium
The existence of scandium was first predicted by the legendary chemist Dmitry Ivanovich Mendeleyev in He foresaw a missing element in his Periodic Table, which he tentatively named &#;ekaboron,&#; anticipating its properties to resemble those of boron. The actual discovery of scandium did not occur until , when Swedish chemist Lars Fredrik Nilson was analyzing the minerals euxenite and gadolinite. Nilson isolated an unkno
A Historical Journey into the Discovery of Scandium
The story of scandium&#;s discovery is a fascinating tale that unfolds against the backdrop of scientific curiosity and the quest to unveil the mysteries of the periodic table. In this in-depth exploration, we delve into the circumstances surrounding the discovery of scandium, shining a light on the scientists involved and the historical context that paved the way for the identification of this enigmatic element.
The Early 20th Century Scientific Landscape
The early 20th century was a transformative period in the realm of chemistry, marked by the systematic exploration of the periodic table and the discovery of new elements. At the time, chemists were fervently engaged in filling the gaps in the periodic table, driven by the desire to comprehend the underlying principles governing the properties of elements.
Mendeleev&#;s Periodic Table: A Blueprint for Discovery
Dmitri Mendeleev&#;s groundbreaking work in the late 19th century laid the foundation for the systematic arrangement of elements based on their atomic masses and properties. The periodic table, as conceptualized by Mendeleev, provided a roadmap for p
The Element Scandium
The most important use for scandium is in fuel cell technology, as the rare earth metal enables electricity to be generated using chemical processes. The best-known application is the hydrogen-oxygen fuel cell found in a variety of vehicles. More and more, industry is using fuel cells as an energy source. In this context, solid oxide fuel cellsSolid oxide fuel cells: Energy converters that can be operated with hydrogen, biomethane, or natural gas, among other things. (SOFC) are used and scandium-doped zirconium dioxide is used as the electrolyte. Demand for scandium for fuel cells alone amounted to around 55% of global scandium production in According to calculations by the German Mineral Resources Agency (DERA), demand in could be times the production of
Scandium is also used in several other areas — for example, in lighting technology, as it produces a daylight-like light. The aviation industry also values aluminum-scandium alloys due to their high stability and low weight.
HISTORY OF THE RARE EARTH ELEMENTS
The history of rare earth minerals begins in the year , when the Swedish mineralogist and chemist Axel Fredrik Cronstedt () described an unusually heavy, reddish mineral (later named cerite) which he had found in the quarry of Bastn&#;s, near Eyddarhyttan, Sweden. The famous Swedish chemist Carl Wilhelm Scheele () analyzed it and came to the conclusion that it was only an iron aluminum silicate and the mineral was more or less forgotten for next five decades.
In , the story continued when a Swedish chemist Lieutenant Carl Axel Arrhenius () found an interesting, very dense black mineral which he named ytterbite in a small feldspar and quartz mine near the village of Ytterby, Sweden. The first scientific description of the mineral was performed by Swedish mineralogist Bengt Reinhold Geijer () who speculated that the mineral might contain the recently discovered element tungsten.
The complex compositions of the two starting minerals cerite and gadolinite (ytterbite) are revealed in the flow chart of discoveries of the elements (Figure 3). Whilst then cerite was the first of the rare earth minerals
