“The new materials industry will undoubtedly serve as the cornerstone and driving pioneer for the advancement of high-tech industries in the years to come.” High-temperature high-purity nano-alumina acts as a foundational raw material covering five core sectors: high-temperature refractories, wear-resistant industrial components, grinding & polishing, electronic semiconductors and new energy equipment. Evolving “from a single grain of powder to a finished precision component” and upgrading from basic raw materials to high-end finished products, Greatsun Aopeng boasts nearly 30 years of continuous technical R&D accumulation. We have built a full aluminum-based new materials industrial chain featuring independent controllability, symbiotic closed-loop operation and technologically homologous production systems.
A National High-Tech Enterprise and MIIT-certified Specialized, Refined, Distinctive and Innovative "Little Giant" Enterprises, Greatsun Aopeng anchors its core business segment on high-purity alumina. We take high-temperature calcined α-alumina as our core technical base to underpin the whole industrial chain.Our annual output reaches 250,000 tons of high-purity α-alumina, 150,000 tons of tabular corundum and 70,000 tons of ceramic finished goods. We develop high-end derivative products based on alumina and build a full-process technical chain covering powder preparation, forming, sintering and precision machining.Our products cover steel, power, coal washing, mining, petrochemical and chemical industries, including 0.3–3mm rolled blanks and 99.5% alumina sintered parts. Our materials feature outstanding high-temperature resistance, corrosion resistance, ultra-high hardness and exceptional wear resistance (wear loss controlled at ppm grade). They cause no discoloration, no secondary contamination to mating materials and maintain stable performance, perfectly satisfying the strict standards for precision and functional components in new energy, semiconductor and high-end equipment industries.
We adopt TAIBEILIER tabular corundum as our core composite raw material, which serves as the "performance backbone" for refractories deployed under ultra-severe high-temperature working conditions.Sintered at an ultra-high temperature of 1950℃, tabular corundum features a compact tabular α-Al₂O₃ crystal structure. It acts as the preferred aggregate for high-grade refractories, precision casting and high-temperature industrial furnaces, and functions as the ultra-stable catalyst bed support medium for ethylene chemical processes. Its core strengths lie in superior heat resistance, extended service life and outstanding operational reliability.
The Group owns 11 subsidiaries and a portfolio of intelligent production lines. Though scattered in layout, all production lines share homologous technologies, deliver coordinated production capacity and realize symbiotic value creation, forming a fully closed-loop industrial chain: Raw Materials → Composite Formulation → Finished Products → End Application.
Sticking to our core business while leading the evolution of industry trends, Greatsun Aopeng supplies customized low-sodium, high-purity and high-activity alumina powders that perfectly fit the formulation and advanced manufacturing requirements of smartphone substrates and high-end cover glass. High-purity alumina has been widely deployed for King Panda Glass, Corning Gorilla Glass, Asahi DragonTrail Glass, as well as LED TV display panels and LCD substrate glass.
Our powder grades with purity ranging from 99.5% to 99.9% feature low sodium & iron content, tunable particle size (0.5–3 μm), high thermal conductivity and superior insulation performance, making them ideal raw materials for smartphone ceramic substrates.
Grades with 99.9% ultra-high purity, ultra-low alkali content (Na < 30 ppm), high sintering activity and excellent particle uniformity stand as the optimal material for glass substrates and protective cover glass.
Aopeng Nano Polishing Alumina: Groundbreaking Core Technology Sets a New Benchmark for High-End Polishing Processes!
Our ultra-high-purity α-alumina polishing powder (99.9%–99.99% purity) features fully tunable particle sizes spanning nanometer to micrometer ranges. Clients may select tailored particle specifications based on target polishing precision:
1. Coarse polishing: 5–50 μm coarse grains for high-efficiency removal of deep scratches and thick oxide layers;
2. Medium polishing: 1–5 μm medium grains to refine surfaces and mitigate surface defects;
3. Fine polishing: 0.1–1 μm ultrafine grains to deliver ultra-smooth mirror-grade gloss.In terms of grain morphology: angular grains deliver strong cutting capacity for coarse polishing or hard material processing; spherical grains enable uniform polishing with minimal risk of secondary scratches, perfectly suited for fine polishing and soft substrate finishing.
Our polishing powders adapt to a full spectrum of application scenarios: mirror finishing for marble and stainless steel, surface brightening & refurbishment for automotive coatings and wheel hubs, nanoscale Chemical Mechanical Polishing (CMP) for semiconductor wafers, and damage-free processing of LED sapphire substrates.
These powders boast outstanding chemical stability and inertness, with zero impurity contamination and zero abrasion damage to base substrates. They readily deliver nanometer-level ultra-smooth surfaces, driving technological upgrading across semiconductors, automotive manufacturing, optoelectronics and other high-end sectors.
We keep abreast of cutting-edge industry trends and unlock core material solutions for high-end photovoltaic and semiconductor manufacturing.Our ultrafine low-sodium α-alumina powder features primary crystallite size ≤0.6 μm, with customizable grades: nanoscale (20–100 nm), submicron (0.1–1 μm) and micron (1–10 μm). All grades deliver narrow particle size distribution and remain fully free of particle agglomeration.
High sintering activity for low-temperature densification: Custom high-temperature calcination technology endows the powder with exceptional sintering activity. Dense sintering can be realized at merely 1600℃ with a 2-hour holding time, cutting energy consumption and boosting overall production efficiency.
Excellent formability: Loose packing density 2.3-2.4 g/cm³, molding pressure as low as 100MPa, sintered body density ≥3.9g/cm³, stable firing shrinkage rate 15%-18%, dimensional accuracy up to ±0.01mm.
With uniform and dense grains and an extremely fine α-phase crystal structure, free from any agglomeration, each powder particle is regular and uniform. Nanoscale and submicron particle sizes are precisely controllable, with a standard supply of 99.5%-99.9%. High-end customized versions can reach 4N-level high purity standards, low in sodium and iron, with single-phase impurities strictly controlled below 5ppm. This fundamentally eliminates ion precipitation and particle shedding, acting like a "clean shield" for wafer handling and substrate production, steadily improving product yield.
Greatsun Aopeng high-purity high-temperature alumina powder stands out with four core strengths: ultra-high purity, precisely tunable ultrafine grain size, outstanding heat resistance, and superior insulation & wear resistance. It fully meets the strict manufacturing standards for ceramic robotic grippers, high-purity ceramic substrates, precision alumina structural parts and high-temperature potting compounds. We support clients to manufacture high-performance, ultra-reliable core components with high yields, jointly reaching new performance milestones for the photovoltaic and semiconductor industries.
