From ore to nanomaterials: the "transformation path" of cerium oxide
In industry, cerium oxide is mainly extracted from rare earth minerals through extraction methods. Chinese enterprises have achieved technological breakthroughs in the preparation of nano cerium oxide:
Anhydrous purification process: Through solvent extraction and vacuum calcination, heavy metal impurities are removed, and the purity reaches 99.999% (5N).
Controllable nano particles: monodisperse nano particles are prepared by spray pyrolysis method, and the particle size uniformity CV value is less than 5% to ensure stable polishing effect.
Case: Nano cerium oxide from Shandong New Materials is used for polishing sapphire substrates, reducing scratch rate by 60% and increasing production efficiency by 30%.
Market and Challenge: Opportunities and Risks Coexist
The global cerium oxide market will reach 1.8 billion US dollars in 2024, with an annual growth rate of 12%. China accounts for 70% of global production capacity, but faces two major challenges:
Price fluctuations: The price of cerium oxide is affected by the rare earth quota policy, and enterprises need to enhance their added value through technological innovation.
Technological substitution: New polishing materials (such as silicone particles) may divert some of the market and require the development of high-end application scenarios.
Future Outlook: From "Traditional Applications" to "Frontier Exploration"
Quantum computing: The crystal structure of cerium oxide provides new ideas for the development of quantum bits, and a research team has achieved stable manipulation of 10 quantum bits.
Solid state batteries: Cerium oxide based electrolytes can improve lithium ion conductivity, enabling battery energy density to exceed 300Wh/kg.
Medical field: Nano cerium oxide, as an antioxidant, can treat neurodegenerative diseases, and clinical trials have shown a symptom improvement rate of 65% in patients.
