【SMM Rare Earth Flash】 The Tianjin Branch of Baotou Research Institute of Rare Earths has achieved a core technological breakthrough in its "Ultra-dry Anhydrous Scandium Chloride Preparation Process Development" project, successfully producing ultra-dry anhydrous scandium chloride with water content below 50 ppm. This marks China's full mastery of synthesis technology for the entire series of rare earth anhydrous halides, filling a gap in high-end scandium-based rare earth functional materials. Since 2017, the team has overcome preparation processes for all rare earth anhydrous halides and built a platform covering light, medium, and heavy rare earth halide industrialization. The product can be applied in laser crystals, specialty light sources, radiation detection, fuel cells, and high-safety lithium batteries, providing key material support for China's low-altitude economy and new energy systems.

[SMM Analysis] Non-China Sintered NdFeB Capacity Map: Tiered Realization of Western Magnetic Material Supply from Estonia's Start of Production

In September 2026, Neo Performance Materials announced that its Narva permanent magnet plant in Estonia began commercial production, with the first batch of sintered NdFeB magnets delivered to an EV traction motor client. The plant was commissioned in September 2025, with Phase 1 capacity of 2,000 mt/year and Phase 2 of approximately 5,000 mt/year in the design stage. The long-term global target is 20,000 mt/year, with dysprosium oxide and terbium oxide secured through the Carester agreement. The significance of this event lies not in "adding another 2,000 mt plant," but in bringing the existing base, in-construction growth, and raw material bottlenecks of magnetic material capacity outside China to the table all at once.

Neo to Provide Separation Tech for Rainbow's Rare Earth Project in South Africa, Aiming 1,800 t/y NdPr Output

【SMM Rare Earth Flash】 Neo Performance Materials has signed an agreement to provide final solvent extraction separation technology to Rainbow Rare Earths' Phalaborwa project in South Africa. The system will extract rare earths from phosphogypsum, targeting 1,800 t/y NdPr and ~80 t/y Dy/Tb. In return, Neo will receive rights to 40% of annual NdPr output and 65% of the enriched concentrate. The agreement is non-binding, with long-term cooperation terms under negotiation. Testing is underway at Neo's Estonia facility, followed by a pilot separation plant in Johannesburg. Rainbow plans a PFS in Q4 and a DFS in H1 next year.

[Note: Translate the Chinese styled brackets "【" and "】" into "[" and "]" respectively.]

This week, rare earth prices outside China remained generally stable, with lanthanum oxide edging up and terbium oxide dipping slightly. Developments in overseas project exploration, smelting, and policy were frequent: resource updates in Brazil, Canada, Greenland, and Saudi Arabia; capacity expansions in Japan, France, and by Lynas expected to come online in 2027–2028; Neo's magnet plant commercialization, with a U.S. company securing military orders; Argentina advancing rare earth legislation, and Arafura locking in a long-term wind power agreement. Short-term supply growth is limited, and large-scale release will take time.
