Rare Earth Manufacturers: Leading Supplier of High-Purity Rare Earth Compounds
Rare earth materials are essential for modern technologies, from electronics and optics to automotive catalysis and renewable energy. For buyers seeking reliable suppliers, understanding the capabilities and product range of key manufacturers is critical. This guide introduces WONAIXI—a professional manufacturer specializing in the R&D and production of rare earth functional materials—and provides a detailed overview of its product portfolio, applications, and quality assurance.
What Are Rare Earth Materials?
Rare earth elements (REEs) are a group of 17 chemically similar metallic elements, including lanthanides and yttrium. While not necessarily scarce, their extraction and processing require advanced chemical techniques. Rare earth compounds, such as oxides, chlorides, carbonates, and sulfates, are used as precursors, catalysts, and functional materials in industries ranging from aerospace to biomedical. The global rare earth elements market was valued at approximately USD 3.95 billion in 2024 and is projected to reach USD 6.28 billion by 2030, driven by demand for clean energy and high-tech applications.
Why Choose a Professional Rare Earth Manufacturer?
Selecting the right rare earth supplier involves evaluating production capacity, product purity, technical support, and compliance with industry standards. Many industrial processes—such as semiconductor manufacturing, optical glass polishing, and automotive catalyst production—require ultra-high-purity raw materials with tight impurity controls. A manufacturer with over 12 years of experience, a dedicated R&D team, and a certified production facility can provide the consistency and reliability needed for critical applications.

WONAIXI supplies 9 major categories of rare earth products plus a complete zirconium salts series, covering over 50 refined specifications.

Comprehensive Product Categories
WONAIXI’s product range includes Rare Earth Nitrates, Chlorides, Carbonates, Hydroxides, Sulfates, Fluorides, Acetates, Polishing Powder, and specialized forms such as Electronic Grade Ammonium Cerium(IV) Nitrate. Below are key products with verified specifications:
- Large Particle Size Cerium Carbonate – Formula Ce₂(CO₃)₃·xH₂O, CAS 54454-25-1. Used as an intermediate for producing cerium compounds, targeting the automotive exhaust purification catalysts industry.
- Cerium Oxide (CeO₂) – CAS 1306-38-3. Used for glass polishing, decolorizing, and as a raw material for cerium metal production, with applications in optics and catalysis.
- Cerium Chloride Heptahydrate (CeCl₃·7H₂O) – CAS 18618-55-8. Used for manufacturing petrochemical catalysts and producing metal cerium.
- Cerium Carbonate – Fine Crystalline Spherical – Spherical morphology with 10–50 nm grains, specific surface area 20–50 m²/g, ideal for high-precision coatings and catalyst supports.
- Cerium Carbonate – Low Chloride – Cl⁻ ≤10 ppm (ultra-low grade ≤1 ppm), crucial for semiconductor and biomedical applications where chloride contamination must be avoided.
Each product is offered in multiple purity grades (reagent, technical, 4N/5N ultra-high purity) to meet diverse industry needs.
Industry Applications
WONAIXI’s rare earth compounds are deployed in high-tech sectors:
| Product | Primary Industry | Function |
|---|---|---|
| Cerium Oxide | Optics / Electronics | Precision polishing of lenses, wafers; UV absorption |
| Ceric Sulfate | Analytical / Water treatment | Oxidizing agent, disinfection, titration reagent |
| Anhydrous Lanthanum Chloride | Semiconductor / Metallurgy | CVD doping, molten salt electrolysis of lanthanum metal |
| Large Particle Size Cerium Carbonate | Automotive exhaust catalysis | Precursor for cerium-based catalysts |

Quality Assurance and Certifications
WONAIXI is certified as a National High-Tech Enterprise and Sichuan Provincial SRDI Enterprise. The company’s 12 engineers in the R&D team ensure strict quality control across all production lines. The facility produces 15,000 tons of high-purity rare earth salts and 3,000 tons of polishing powder annually, with export ratio of 10% to markets including Japan, South Korea, USA, France, and the UK.

Working Conditions and Handling Guidance
To ensure safe and effective use, each product has specific handling requirements. For example, Anhydrous Lanthanum Chloride is extremely hygroscopic and must be stored in argon-sealed containers at 15–25°C with RH<50%. Operations must be performed in a glove box or fume hood. Similarly, Ceric Sulfate is a strong oxidizer that requires separation from reducing agents and storage in acid-resistant containers. WONAIXI provides detailed SDS and technical support for all products.
Step-by-Step Procurement Guide
- Identify Application – Define the industry and process requirements (e.g., catalyst precursor, polishing slurry, electronic film).
- Select Product Grade – Choose from reagent, technical, or 4N/5N ultra-high purity based on impurity tolerance.
- Request Specification Sheet – Contact WONAIXI to obtain detailed product parameters, CAS numbers, and impurity limits.
- Order Sample – Validate performance in your process with a small batch before full-scale production.
- Place Bulk Order – Leverage WONAIXI’s capacity (15,000 tons/year) for reliable, large-volume supply.
