What are 3 uses for lanthanum?
Lanthanum and other rare-earth compounds are used in carbon arc lighting, specifically in the film and television industry for studio lighting and projection. Lanthanum oxide (La2O3), also called lanthana, improves the alkali resistance of glass and is used in making camera lenses and in other special glasses.
Is scandium a precious metal?
Scandium is perhaps the closest we come to a precious metal outside of proper precious metals. Despite being a useful metal with many desirable characteristics (lightweight yet high strength, resistance to corrosion, non-toxic, etc.) its rarity dooms its potential to all but very specific applications.
How much does a pound of 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.
Is titanium a element?
Titanium is the ninth most abundant element on Earth. It is almost always present in igneous rocks and the sediments derived from them. It occurs in the minerals ilmenite, rutile and sphene and is present in titanates and many iron ores.
Is scandium highly reactive?
Named after Scandinavia, scandium is a soft, silvery-white metal. It is reactive and will tarnish to a yellowish or pinkish color in air. If water is run over it, a reaction that releases hydrogen gas will result. Scandium is also very reactive with acids.
What is titanium used for?
Titanium is a familiar metal. Many people know that it is used in jewelry, prosthetics, tennis rackets, goalie masks, scissors, bicycle frames, surgical tools, mobile phones and other high-performance products. Titanium is as strong as steel but weights about half as much.
Why is titanium dangerous?

Is titanium worth more than gold?
Titanium is usually cheaper than white gold. However, because of its hardness, titanium is not as easy to work with. In such cases, the additional labor costs may make the price of a titanium ring comparable to that of a white gold one (or even higher).
Does magnet attract titanium?
Titanium is a paramagnetic material that is not affected by the magnetic field of MRI.
Is Titanium stronger than steel?
Titanium is highly valued in the metals industry for its high tensile strength, as well as its light weight, corrosion resistance, and ability to withstand extreme temperatures. It’s as strong as steel but 45% lighter, and twice as strong as aluminum but only 60% heavier.
