II. Diverse Application Fields

(1) Electronic Information Polishing Field:Helping the Upgrading of Precision Machining

As a core polishing material in the electronics information industry, it is widely used in the polishing of precision components such as smartphone cover glass, LCD panel panels, semiconductor silicon wafers, and optical lenses. Its unique "chemically mechanical polishing" mechanism can remove surface defects through oxidation-reduction reactions while physically grinding, increasing the polishing rate by 30% compared to traditional materials, and controlling surface roughness below Ra0.5nm, effectively enhancing product light transmittance and surface finish. It has been adapted to the polishing processes of multiple leading electronics manufacturing companies, supporting mass production needs for high-end products like 5G terminals and ultra-high-definition displays.

(2) Catalysis and Environmental Protection: Empowering Green Production

This material demonstrates exceptional catalytic potential as a core active component in automotive exhaust purification systems. Through Ce³⁺/Ce⁴⁺ redox conversion, it enables oxygen storage and release, effectively catalyzing NOx reduction, CO oxidation, and hydrocarbon decomposition to meet China's National VI emission standards. In industrial applications, it enhances catalytic combustion efficiency by lowering activation energy thresholds. As a sustainable oxidation catalyst in chemical synthesis, it replaces traditional heavy metal catalysts, reduces environmental pollution, and supports eco-friendly production processes for pharmaceutical intermediates and fine chemical products.

(3) Ceramics and Glass: Strengthening Material Properties

In ceramic manufacturing, when used as stabilizers and toughening agents, these additives significantly enhance the material's flexural strength and thermal stability, making it suitable for demanding applications such as aerospace engine components, dental implants, and high-end cutting tools. In glass production, they function as decolorizing agents to remove ferrous ion impurities and improve transparency. As radiation-resistant glass additives, they strengthen the glass's shielding capability against gamma rays and X-rays, finding applications in medical imaging equipment and nuclear industry protective glass.

(4) New Energy and Energy Storage: Expanding the Boundaries of Application

Breakthroughs in new energy applications continue to emerge. As electrolyte materials for solid oxide fuel cells, they significantly enhance oxygen ion conduction rates while reducing operating temperatures. In lithium-ion batteries, when used as cathode material coatings or additives, they inhibit electrolyte decomposition, improving cycle life and safety to meet the high energy density demands of power and energy storage batteries. Additionally, they can be applied in manufacturing transparent conductive films for solar cells, thereby boosting photoelectric conversion efficiency.
