What are the rare metals? Characteristics and Applications of Rare Metals

1、 Definition and classification of rare metals

Rare metals refer to metal elements with relatively low content and sparse distribution in the Earth's crust. They can be roughly divided into the following five categories:

Light rare metals: such as lithium (Li), beryllium (Be), magnesium (Mg), etc. They have the characteristics of low density and high strength, and are widely used in fields such as aviation, aerospace, and new energy.

Heavy and rare metals: such as tantalum (Ta), tungsten (W), rhenium (Re), etc. This Metalloid has high density, high melting point, high strength and other characteristics. It is an important raw material for manufacturing high-temperature alloy, high-strength steel and other materials.

Rare earth metals: including 15 Lanthanide (La Lu), scandium (Sc) and yttrium (Y). Rare earth metals have unique physical and chemical properties and are widely used in fields such as optics, electronics, and magnetic materials.

Disperse metals: such as indium (In), germanium (Ge), gallium (Ga), etc. The distribution of dispersed metals in the crust is very dispersed, usually in the form of composite minerals. This Metalloid has important application value in semiconductor, photovoltaic, optical communication and other fields.

Radioactive metals: such as uranium (U), thorium (Th), plutonium (Pu), etc. These metals have high levels of radioactivity and are mainly used in the field of nuclear energy.
