Typical impurity control levels by purity grade:
5N-grade products can achieve low-ppm levels for key impurities such as Na (≤2 ppm), Fe (≤0.8 ppm), and Si (≤1.2 ppm). 4N-grade products typically control Na, Fe, and Mg below 10 ppm, with specific limits depending on the downstream application and product designation.
Products are supplied in 4N, 4N5, and 5N grades. Particle size distribution and morphology (spherical, near-spherical, prismatic, etc.) can be adjusted to meet application requirements.
Sapphire & Optoelectronics:
LED Sapphire Substrates: 5N-grade HPA is the primary feedstock for synthetic sapphire single crystals used in LED substrates, optical windows, lasers, and infrared optics.
Optical & Window Materials: Sapphire single crystals leverage high transmittance, hardness, and electrical insulation for optical instruments, high-pressure/high-temperature viewing windows, and infrared windows.
New Energy & Battery Materials:
Lithium Battery Ceramic Separator Coatings: 4N5+ nano α-alumina is coated onto PP/PE separator films to provide high-temperature resistance, insulation, and dimensional stability, preventing separator melting and short circuits at elevated temperatures.
Solid-State Batteries: 4N HPA serves as a key component or coating material in solid-state battery systems, with higher usage than in conventional ceramic-coated separators.
Luminescent Materials:
Rare-Earth Trichromatic Phosphors: 4N-grade HPA is a primary raw material for trichromatic phosphors used in fluorescent lamps and related lighting products.
PDP & Long-Persistence Phosphors: 5N-grade products are used in plasma display panel phosphors and other high-performance luminescent systems.
Advanced Ceramics & Semiconductors:
Transparent Ceramics: Used in high-pressure sodium lamp envelopes and similar applications requiring high-temperature resistance, sodium corrosion resistance, and high transmittance.
Semiconductor Ceramic Components: High-end 4N5/5N grades (U, Th <1 ppb) are used in wafer-adjacent ceramic tools and components meeting zero-alpha emission requirements.
IC Substrates & Insulating Components: High insulation and chemical stability suit electronic ceramic substrates, headers, and housings.
Precision Polishing & Surface Treatment:
Precision Polishing: High-purity nano alumina is used for mirror polishing of sapphire, glass, metals, semiconductors, and plastics, offering high polishing efficiency with minimal surface defects.

Q1: Is your company a trading firm or a manufacturing plant? Where are your facilities located?
We are an export-oriented enterprise that integrates manufacturing and sales; we are not an intermediary. Our headquarters—handling international sales, order processing, documentation, and after-sales service—is located in the Liaocheng Economic and Technological Development Zone, serving as the hub for global client relations, order negotiations, and cross-border services. Our production facility is situated in Chiping District, Liaocheng City, and specializes in the R&D, smelting, processing, and testing of white fused alumina, brown fused alumina, and other fused alumina products. This allows us to manage the entire supply chain—from primary production and rigorous quality control to direct export.
Q2: What is your production capacity and supply capability? Can you ensure a stable, long-term supply?
Our production base in Chiping features mature production lines and comprehensive processing equipment, enabling large-scale, continuous manufacturing. We offer a stable supply of our full range of white fused alumina, brown fused alumina, and related fused alumina products. With ample inventory and well-organized production scheduling, we are fully equipped to handle bulk orders, recurring annual orders, and urgent requests during peak seasons, ensuring a reliable, long-term supply for our global clients.
Q3: What are your primary export products, and what are your core offerings?
Our core exports consist of three main series of fused alumina materials: brown fused alumina, white fused alumina, and other fused alumina products. We offer a comprehensive range of specifications and particle sizes that meet various international procurement standards. Brown fused alumina is our flagship product for cost-effective industrial abrasives and refractory raw materials; white fused alumina is designed for high-purity, high-precision grinding and polishing applications; and our broader fused alumina line serves high-end refractory, specialty ceramic, and precision abrasive tool sectors—covering the full spectrum of procurement needs across all market tiers.
Q4: What are the specific applications for these three types of fused alumina, and how should one choose the right product? 1. Brown Fused Alumina: Characterized by high toughness, excellent wear and impact resistance, and a strong price-performance ratio. It is suitable for general industrial applications such as metal sandblasting (rust removal), hardware grinding, the manufacturing of grinding wheels and sandpaper, metallurgical castable refractories, and lining materials for standard industrial furnaces. It serves as a versatile, all-purpose abrasive and refractory raw material.
2. White Fused Alumina: Features high purity, high hardness, and excellent self-sharpening properties, with a pure white appearance free from impurities. It is ideal for high-precision and high-cleanliness applications, including the polishing of precision molds, grinding of aerospace components, finishing of electronic materials, and the production of high-end refractory products and precision ceramics.
3. Fused Alumina (High-Purity/Specialized): Possesses a dense structure, exceptional thermal stability, and high resistance to both heat and corrosion. It serves as a core raw material for high-end, specialized refractories, structural ceramics, precision grinding media, and linings for high-temperature industrial kilns, making it well-suited for demanding, high-performance operating environments.
