RARE EARTHS

Rare Earths are a group of 15 chemical elements belonging to periodic table.
The most commonly used rare earths are Cerium, Erbium, Neodymium, Praseodymium.
AMPI srl is distributor on the national and European market since several years of here below rare earths.

Types of Rare Earths

 

Cerium

Cerium is a metallic element, ductile and malleable belonging to lanthanides. It can be used, in its different forms, in ceramic, glass, automobile, high-tech industry and more.
   Cerium Carbonate

It is mainly applied in making auto catalyst and glass, and also as a raw material for producing other Cerium compounds. Important element in semiconductors industry.

   Cerium Nitrate

Colorless granular crystals. It is used for separation of Cerium in rare earths and catalyst for hydrolysis of phosphoric acid esters.

   Cerium Oxide

Very efficient polishing and decolorizing agent in glass industry. It can be added to glass in order to obtain the Ultra violets absorption. It is a good catalyst in organic reactions. It is part of Mischmetal, largely used in the manufacturing of pyrophoric alloys for lighter flints.

 

Erbium

Erbium is a soft, malleable metal. The biggest exporters are China and United States. It has a good UV rays absorption capability therefore it is largely used in the manufacture of special protective eyeglasses. Added to vanadium, it increases its workability.
 

Thanks to its pink color, Erbium oxide is used as colorizing agent for ceramics and glasses.   

 

Lanthanum

Lanthanum is a light metal, silver-white colored, malleable and ductile. It is used by itself or together with cerium and other lanthanides under the name of ‘mischmetal’ in the metallurgical industry of ferrous and nonferrous alloys. Small quantities of lanthanum added to steel make it more ductile, malleable and more resilient.


Lanthanum oxide (La2O3) improves glass resistance to attack of alkali, this is why it is largely used for manufacturing special optical glasses.

 

Neodymium

Neodymium is a silver-yellow metal, oxidizes when exposed to air. After the cerium is the second most abundant element in Earth's crust. It is used in the manufacture of fluorescent lamps, energy saving lamps and televisions. The most important alloy is  neodymium, iron and boron (NdFeB) which is used for manufacturing magnets for computers, speakers, vehicles, CD and DVC players.
 

Neodymium oxide is used to give to glass a nice purple color.
 

Praseodymium

Praseodymium is a soft metal, silver-yellow colored belonging to lanthanides. There is plenty of it in the earth’s crust. It is a good bonding agent of magnesium for the production of high-resistance alloys in aircrafts engines.

 

Oxides are used for manufacturing special lenses and for coloring in yellow glass and glaze ceramics.
