Oxide to Power: An Obscure Midstream (Metallization) Market Controlling Trillions in Global Industry

Highlights

• China dominates 85–90% of rare earth metallization and alloying capacity, the critical midstream step converting oxides into usable metals, alloys, and magnet feedstock for defense, EVs, and AI infrastructure.
• The ex-China rare earth metallization market could grow from $500M–$1B today to $3–5B by 2035 as the UK, US, Japan, South Korea, and Australia build parallel industrial systems for strategic sovereignty.
• Metallization requires dangerous pyrometallurgy, molten salt electrolysis, and years of customer qualification—a technically unforgiving sector that sits at the choke point of trillions in downstream industrial activity.

The real battle in rare earths is no longer mining. It is the midstream—the dangerous, capital-intensive, technically unforgiving world of not only concentrate/carbonate to oxides but the metallization, alloying, strip casting, powder production, and magnet feedstock preparation. This is where separated oxides become usable industrial products. It is also where China still overwhelmingly dominates, controlling roughly 90% or more of rare-earth metallurgical and alloying capacity and an even larger share of downstream permanent-magnet production.

For decades, the West outsourced this industrial layer because China offered lower costs, looser environmental controls, patient state-backed capital, and relentless industrial scaling. Now, in what Rare Earth Exchanges™ calls the Great Powers Era 2.0, governments increasingly view supply chains not as commercial conveniences but as instruments of geopolitical power. That realization is driving a quiet but strategically important midstream renaissance.

The Market

The global market for metal oxides is large and expanding, but investors should separate three related categories: broad nanometal oxides, metal oxide nanoparticles, and the much narrower rare-earth oxide-to-metal metallization/alloying market. Grand View Research estimates the global nano metal oxide market at $6.68 billion in 2023, growing at 9.9% CAGR through 2030, while Mordor Intelligence estimates the metal oxide nanoparticles market at $1.11 billion in 2026, rising to $1.54 billion by 2031 at 6.74% CAGR, driven by electronics, optics, semiconductors, batteries, coatings, and energy applications. By contrast, rare earth metallization and alloying—the conversion of NdPr, Dy, Tb and related oxides into metals, alloys, powders, and magnet feedstock—is smaller but strategically more critical. Including China, REEx estimates this rare earth midstream segment is likely a multi-billion-dollar market today, with China controlling roughly 85–90%+ of capacity across metallization, alloying, strip casting, powders, and magnet manufacturing. Ex-China rare earth metallization/alloying likely remains only about $500 million–$1 billion today, but could grow toward $3–5 billion by 2035 if Western projects in the U.S., UK, Europe, Japan, South Korea, and Australia scale successfully.

The broader oxide market reflects demand pull from AI chips, semiconductors, batteries, EVs, coatings, and advanced electronics; the rare-earth-specific opportunity is narrower, harder, and more geopolitically sensitive. In Great Powers Era 2.0, oxide-to-metal capability is no longer just a manufacturing step—it is becoming strategic industrial power.

The apparent size of the rare earth metallization and alloying market is deceiving because, much like rare earth mining and oxide separation, it represents a relatively small midstream industrial layer that enables an enormous downstream economic ecosystem. The actual revenues generated from converting oxides into metals, alloys, powders, and magnet feedstock may only total several billion dollars globally today, yet these materials underpin trillions of dollars of downstream activity across defense systems, EV drivetrains, robotics, semiconductors, AI infrastructure, aerospace, industrial automation, renewable energy, consumer electronics, telecommunications, and advanced medical technologies.

Without metallization, the oxide is largely unusable for high-performance magnets and advanced applications. In practical terms, this means relatively small metallization facilities sit at the choke point of entire industrial civilizations. That asymmetry is precisely why governments increasingly view metallization and alloying not as niche industrial chemistry—but as strategic infrastructure central to Great Powers Era 2.0.

Ex-China Action

The United Kingdom has emerged as one of the most interesting battlegrounds. Less Common Metals (opens in a new tab) (targeted for acquisition by USA Rare Earth) remains one of the few Western specialists with decades of rare-earth alloying experience, producing NdFeB and SmCo alloys for advanced applications. Nearby, HyProMag (opens in a new tab) is building a recycling-centered magnet ecosystem using Hydrogen Processing of Magnet Scrap (HPMS) technology, attempting to bypass parts of the traditional mine-to-metal chain entirely.

Another intriguing UK player is Metalysis (opens in a new tab), which is developing electrochemical pathways for specialty metal and alloy powders. While not yet a dominant rare earth metallizer, the company represents the broader push toward lower-energy, next-generation metallurgical approaches. They have been back by over $100 million in investment from an Canadian investor.

Meanwhile, the United States is attempting its own midstream awakening. MP Materials (opens in a new tab), Phoenix Tailings (opens in a new tab), Noveon Magnetics (opens in a new tab), and others are building domestic capabilities in alloying, metallization, and magnet production tied to EVs, defense systems, robotics, aerospace, and AI infrastructure. South Korea’s Australian Strategic Materials  (Energy Fuels buying), Korean Metals Plant, and Japan’s Proterial continue advancing non-Chinese alloy and magnet expertise. Other players in the rare earth metallization midstream include ReElement Technologies (opens in a new tab) and Evolution Metals & Technologies (opens in a new tab). Other startups dot the emerging ecosystem as well.

Challenges

Investors should remain sober. This sector is extraordinarily difficult. Metallization requires pyrometallurgy, molten-salt electrolysis, oxygen control, hazardous powder handling, process-chemistry expertise, and years of qualification with automotive and defense customers. China did not build this ecosystem overnight.

The market trajectory, however, is undeniable. Global demand for NdFeB magnets continues to accelerate across EVs, wind turbines, robotics, drones, AI infrastructure, and electrification. Rare Earth Exchanges has forecast that magnet rare earth demand will rise sharply through 2030 and beyond.

The result is clear: The world is rebuilding a parallel midstream industrial system outside China. It will take years. It will cost billions. It will likely remain inflationary. But increasingly, governments view that cost as the price of industrial sovereignty.
