Storyboard Text
- Slide: 1
- Gadolinium (Gd) Atomic Number 64
- Jean Charles de Marignac first extracted gadolinite from didymium when he learned that didymium had different spectral lines in different areas.
- Chemistry 101Notes on Gadolinium discovery*Jean Charles de Marignac used spectography*location: in the Urals*main compound it was discovered in: samarskitelargest deposit: Bayan Obo iron ore deposit in southern Mongolia, China*There are trace amounts of it in the universe
- Slide: 2
- Gd where is it found? pure or compound? how do you isolate it?
- 1. India, Sri Lanka, China, Brazil, Australia, S. Africa the US 2. it is always a compound unless it is extracted3. Gd is isolated by chemical processes that extract it from compounds bysolvent-solvent extraction or ion exchange

- Slide: 3
- Gd usesNow: phosphors in fluorescent lamps, X-ray screens tomography, MRI contrast, nuclear reactor shields and control rodsIn the Past: used in magnetic fridges TV screens, computer memory imitation diamonds
- Gd is very important economically for magnets, fine ceramics, petrochemical catalysts, metallurgical casting and optical glass. It is a superconductor in engines and generators
- What is its economic importance?it is used for asthma treatment, medical imaging in Canada and around the world. This helps with medical diagnosis and saves lives.its magnetic properties make it important for electronic components, high-performance magnets and optical devices.it is important for control rods in nuclear reactors.it is used for climate change technologies.it is found in monazite and bastnasite with are important sources of titanium and tin.
