Rare Earth Products and Their Industrial Applications: A Comprehensive Guide

Sichuan Wonaixi New Materials Technology Co., Ltd. (WONAIXI) is a professional manufacturer founded in 2012, specializing in the research, development, and production of rare earth functional materials. Certified as a National High-Tech Enterprise and Sichuan Provincial SRDI Enterprise, the company supplies over 50 refined specifications across 9 major rare earth product categories, including nitrates, acetates, fluorides, chlorides, oxides, carbonates, hydroxides, sulfates, and zirconium salts. With an annual output of 15,000 tons of high-purity rare earth salts and 3,000 tons of high-precision rare earth polishing powder, WONAIXI serves industries ranging from optics and catalysis to electronics and new energy.

Understanding Rare Earth Materials

Rare earth elements (REEs) are a set of 17 chemically similar metallic elements that are critical for modern technologies. The global rare earth elements market was projected to reach approximately USD 14.03 billion in 2025, with magnet applications accounting for 31.2% of total value (IMARC Group, 2025). China’s rare earth exports reached 62.6 thousand metric tons in 2025 (General Administration of Customs/Statista). WONAIXI plays a key role in this supply chain, exporting 10% of its production to Japan, South Korea, USA, France, and the UK.

Why Choose WONAIXI for Rare Earth Materials?

WONAIXI operates a manufacturing facility of approximately 46,667 m² with a dedicated R&D team of 12 engineers. The company’s annual capacity of 18,000 tons (15,000 tons high-purity rare earth salts + 3,000 tons rare earth polishing powder) ensures stable supply for bulk and specialty orders. Key differentiators include strict impurity control, customizable purity levels (4N, 5N, 6N), and specialized morphologies such as spherical and fine crystalline forms.

Product Categories and Applications

Rare Earth Nitrates

WONAIXI supplies high-purity nitrate compounds including Lanthanum Nitrate Hexahydrate (CAS 10277-43-7), Cerium Nitrate Hexahydrate (CAS 10294-41-4), Praseodymium Nitrate Hexahydrate (CAS 15878-77-0), Neodymium Nitrate Hexahydrate (CAS 16454-60-7), and Yttrium Nitrate Hexahydrate (CAS 13494-98-9). These are used as precursors for ternary catalysts, ceramic materials, and chemical reagents.

Rare Earth Acetates

Products like Lanthanum Acetate Hydrate (CAS 100587-90-4) and Cerium Acetate Hydrate (CAS 537-00-8) serve as mild Lewis acid catalysts and precursors for thin-film deposition, offering dual solubility in water and ethanol for versatile processing.

Rare Earth Fluorides

Cerium Fluoride (CeF3, CAS 7758-88-5) and Lanthanum Fluoride (LaF3, CAS 13709-38-1) are used in optics for optimizing glass properties, producing optical thin films, and as additives for fluorescent powders. Praseodymium-Neodymium Fluoride is a key material for high-performance optical lenses and rare earth metal smelting.

High-Purity Oxides

WONAIXI provides Lanthanum Oxide (La2O3, CAS 1312-81-8), Cerium Oxide (CeO2, CAS 1306-38-3), and Neodymium Oxide in 4N/5N grades. These are essential for glass decolorization, polishing, and as raw materials for rare earth luminescent materials. High Purity Cerium Carbonate (CAS 54451-25-1) with ppb-level impurity control is used for automotive exhaust catalysts and dielectric thin films.

Specialty Carbonates

WONAIXI offers a range of cerium carbonates tailored for specific needs: Low Chloride Cerium Carbonate for catalyst applications requiring minimal halide contamination, Fine Crystalline Spherical Cerium Carbonate for uniform coating and fixed-bed catalysis, and Large Particle Size Cerium Carbonate for dust-free ceramic and metallurgy processes.

Step-by-Step Guidance for Sourcing Rare Earth Materials

1. Identify Application Requirements – Define purity, particle size, morphology, and solubility needed for your process.
2. Review WONAIXI’s Product Portfolio – Over 50 specifications allow matching to most industrial needs.
3. Request a Technical Data Sheet – WONAIXI provides Certificates of Analysis for each batch to verify impurity levels.
4. Order Samples – Small quantities (kg) are available for testing before bulk commitment.
5. Scale to Production – Annual capacity of 18,000 tons ensures timely fulfillment of large orders.
