Scarce precious metals, also known as rare metals, are also rare element metals. Commonly used rare metals are lithium, titanium, radium and so on.

Rare elements are the general name of elements that are stored and distributed sparsely in nature (generally below 100ppm crustal abundance) and less applied by human beings. Rare elements are often used to make special metal materials, such as special steel, alloys, etc., which are key materials in aircraft, rockets, atomic energy and other industrial fields.

According to their physical, chemical properties and production methods, they can be divided into:(1) rare light metals, such as beryllium, lithium, rubidium, cesium, etc.;(2) rare precious metals, such as platinum, iridium, osmium, etc.;(3) rare dispersed metals, such as gallium, germanium, indium, thallium, etc.;(4) rare earth metals, such as scandium, yttrium, lanthanum, cerium, neodymium, etc;(5) refractory rare metals, such as titanium, zirconium, tantalum, vanadium, niobium, etc.;(6) radioactive rare metals, such as polonium, radium, actinium, uranium, plutonium, etc.
