Overview of Rare Earth Element Applications

Rare Earth Elements are metals, with high lustre and electrical conductivity. In colour, they are typically silver, silvery-white or grey that tarnish when exposed to air, thereby forming oxide compunds. Chemically, REE's are strong reducing agents, their compounds are generally ionic, and they display high melting and boiling points. REE's are relatively soft in their metallic state metals, thehardness of which increases with higher atomic numbers.

REE's react with other metallic and non-metallic elementsa to form a wide range of compounds, each with specific chemical behavious. These compounds commonly fluoresce strongly under ultraviolet light, which may assist in their identification. REE compounds generally react with water or dilute acid to liberate hydrogen gas. Many REE compounds are strongly paramagnetic.

The REE's chemical properties make them indispensable and non-replaceable in many electronic, optical, magnetic and catalytic applications. Rare Earth Element consumption is growing, due to their daily contribution to our lives in products like hybrid cars, catalytic converters, wind power generators, household appliances, industrial motors, MRI machines, iPods and computer hard drives. Rare Earth Elements are essential in the growing field of green energy technology. Tasman Metals Ltd's projects have the capacity to deliver secure supply of these essential metals to near-by European consumers.


Global warming is a concern for us all and a current major policy focus for domestic and international governments and agencies. Rare Earth Elements are playing a vital role in limiting green house gas emissions, through their unique application in green energy technologies, including hybrid and electric vehicles and wind power generators, so reducing hydrocarbon consumption.

Governments are legislating for lower emission standards in both domestic and industrial settings through carbon-trading and other policies, driving a change to such green energy technologies.


High technology applications characterise the modern era, with digital products contributing to every part of modern life. Audio-visual, photographic, communication, and music devices surround us at home, work and on the move.

Rare Earth Elements facilitate this technology, with new materials and novel applications of them enabling more efficient, higher performance materials which meet the demand for faster, smaller and lighter products with longer battery life.


Prudent use fossil fuel reserves is vital in the modern carbon constrained "peak oil" world. Population growth and improving living standards have lead to greater demands on the world's energy resources. Rare Earth Elements play a vital role in conservation of these reserves by improving efficiency and reliability of hydrocarbon driven machinery. Ni Metal Hydride batteries provide a cost effective and efficent source of transportable power.

Automotive catalytic converters, high strength magnets that reduce friction, alloys that reduce operating weights, hybrid vehicles, and energy efficient fluorescent light bulbs and phosphor-based light-emitting diodes consume REE's and have a growing role to play in modern society.


Health and medical technology is developing at a quickening pace. The scientific community is making great advances, identifying new applications for organic and inorganic compounds and developing new techniques and machines to detect and treat illness and monitor human health.

Rare Earth Elements play a vital role in such new technologies, being essential in MRI machines used for medical imaging and diagnostics, in high intensity phosphors used in imaging, and as tracers.
