Rare earth elements can be used to produce molecular sieve catalysts in petroleum catalytic cracking processes, which have the advantages of high activity, good selectivity, and strong resistance to heavy metal poisoning. They can significantly improve the conversion rate of crude oil cracking and increase the yield of gasoline and diesel.

In ceramic raw materials, doping a certain amount of rare earth elements not only improves the sintering properties, density, microstructure, phase composition, and physical and mechanical properties of ceramics, but also enhances their electrical, optical, or thermodynamic properties, which can meet the performance requirements of ceramic materials used in different occasions.

Adding a certain amount of rare earth elements to rubber synthesis can increase the heat resistance and mechanical properties of rubber.

Rare earths are known as the "treasure trove of new materials in the 21st century" and are widely used in various fields of the national economy and advanced manufacturing, such as electronics, communications, lighting, healthcare, new energy, biotechnology, new energy vehicles, and energy conservation and environmental protection.
