Lanthanum phosphate occupies a key position in rare earth chemistry, with applications in polishing powders, catalysts, optics, and specialty materials. Global production has expanded from a small base over the last decade, tracking growth in rare earth mining and separation capacity, particularly in China, which remains the dominant source of lanthanum. Additional contributions come from producers in other Asia-Pacific countries, North America, and Europe, often focusing on high-purity grades. Lanthanum phosphate production trends have followed investment cycles in rare earths, including periods of accelerated capacity build-out and subsequent rationalization. Price trends for lanthanum phosphate primarily reflect lanthanum oxide pricing, processing costs, and purity specifications. Rare earth price spikes—often driven by policy changes, supply interruptions, or demand surges—translate into higher lanthanum phosphate prices, especially for high-purity grades used in sensitive optical and catalytic applications. The 2020–2022 period saw elevated rare earth prices and freight rates, leading to noticeable increases in lanthanum phosphate pricing.
