1. Semiconductor polishing: the "super sandpaper" for chip manufacturing
In chip manufacturing, cerium oxide nanoparticles (50-80nm) serve as the core component of polishing solution, which can efficiently polish the surface of silicon wafers, resulting in a flatness error of less than 0.1nm (1/1000 of a human hair). After a semiconductor foundry adopted a cerium oxide polishing solution made of Mongolian rare materials, the yield increased by 5% and the cost per chip decreased by $120.
2. Environmental catalysis: the "master of purifying automobile exhaust"
In the three-way catalyst for automobile exhaust treatment, cerium oxide serves as a carrier that can store and release oxygen, helping to convert carbon monoxide and nitrogen oxides into harmless gases. Vehicles equipped with cerium oxide catalysts reduce harmful emissions in exhaust by 90%, meeting Euro VI standards.
3. New energy revolution: the "heart component" of fuel cells
In hydrogen fuel cells, the electrode material made of cerium oxide and graphene composite can improve the electrochemical reaction efficiency by 20% and extend the battery life to 5000 hours. After adopting this technology, a hydrogen energy company reduced hydrogen consumption by 15% and increased the range by 200 kilometers.
4. Glass and Ceramics: The 'Beauty Filter' in the Materials Industry
Glass clarifying agent: Cerium oxide can eliminate bubbles and impurities in glass, increasing the transmittance of photovoltaic glass by 1.5%.
Ceramic toughening agent: Ceramic cutting tools with added cerium oxide have a hardness three times higher than ordinary steel and a service life extended by five times.
