China Northern Rare Earth Develops Large-Particle Cerium Carbonate for High-End Polishing Powders

Highlights

• Hefa Rare Earth independently developed large-particle cerium carbonate with tightly controlled particle sizes and improved batch-to-batch consistency.
• The technology has passed laboratory-scale validation but commercial-scale production has not yet been demonstrated.
• Cerium carbonate serves as a precursor for polishing materials used in smartphone cover glass, optical glass, and precision instruments.
• Western supply-chain planners face a challenge beyond mining: competing requires qualification-grade specialty materials and reproducible process recipes.
• Baogang plans to scale up and commercialize the product as part of a broader strategy to develop higher-end rare-earth separation and refining materials.
