FAQ
Frequently Asked Questions
In stable, chelated compounds used in medicine, it is generally safe. However, free gadolinium ions are toxic, and its use is strictly controlled.
It has unique magnetic properties, making it valuable for data storage, MRI machines, and manufacturing compact, strong magnets for electronics.
It is more abundant than metals like silver or gold but is difficult to separate from other rare-earth elements, making it relatively scarce in pure, usable form.
Yes, but it is primarily sold to industries and research laboratories, not to the general public, due to its specialised applications and cost.
