What is cerium used for?

Uses of ceriu. Cerium oxide is used in incandescent gas mantles, as a glass polishing agent and as a catalyst in self-cleaning ovens. Cerium is also extensively used in the film and television industry in carbon arc lighting for studio lighting and projector lights.

What are the 7 rare earth elements?

Rare-earth oxides (clockwise from top center): praseodymium, cerium, lanthanum, neodymium, samarium, and gadolinium. What is light REE? Light REEs (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium and scandium) are produced in global abundance and are in surplus supply. Heavy REEs (terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and yttrium) are produced mainly in China and are in limited supply.

Keeping this in consideration, is strontium an incompatible element?

Consequently, in mantle systems, strontium is an incompatible element, strongly enriched in the melts. In crustal systems the extensive involvement of the feldspar minerals can produce large depletions in crustally derived melts; some granites contain < 10 ppm Sr. Is RB incompatible or compatible? Incompatible elements include Rb, Sr, Nd, and light rare earth elements (LREE) in general. Igneous rocks produced as the result of different processes can have a wide range of isotopic signatures.

Why is continental crust enriched incompatible elements?

The Composition of Earth's crus. We call the elements that are enriched in the crust "incompatible" elements because they do not fit into structural sites in the major mantle mineral phases. When the mantle melts, they enter the melt phase and eventually end up in the crust.
