Product Application
Our products are all high-performance alumina materials, which play important roles in various high-end industrial fields due to their distinct physical and chemical properties.
1. Low-Sodium White Fused Alumina
Features: By reducing sodium oxide content, it achieves higher purity, thermal stability and mechanical strength, and minimizes grain boundary corrosion at high temperatures.
Main Applications:
● High-grade Refractories: Used for key components such as furnace linings, sliding plates and nozzles in iron & steel and non-ferrous metal smelting industries, with strong corrosion resistance.
● Ceramics Industry: Acts as a reinforcing phase for structural ceramics (e.g. wear-resistant ceramic parts, ceramic membrane supports), improving density and toughness.
● Precision Casting: Applied as surface layer material for high-end investment casting shells, enhancing the surface finish of castings.
● Grinding & Polishing: Used in manufacturing high-end grinding wheels and lapping discs for precision grinding of cemented carbides and stainless steels.
2. High-Purity White Fused Alumina
Features: Extremely high alumina purity with minimal impurities, high hardness, excellent thermal conductivity and strong chemical inertness.
Main Applications:
● Semiconductor Manufacturing: Used for wafer polishing, insulating components and corrosion-resistant chambers in semiconductor equipment.
● LED & Optics Industry: Serves as raw material for sapphire substrates (single-crystal alumina), applied in LED chips and optical windows.
● High-Performance Ceramics: Used in producing transparent ceramics, laser devices and biomedical ceramics (e.g. artificial joints).
● High-Temperature Thermal Insulation: Manufactures alumina fibers and lightweight insulating bricks for aerospace thermal protection systems.
3. Calcined Alumina
Features: Crystal form (e.g. α-alumina) is controlled via high-temperature calcination, featuring high sintering activity, controllable particle size and pore structure.
Main Applications:
● Catalyst Carriers: Porous supports for petrochemical and automotive exhaust purification catalysts, providing high specific surface area and thermal stability.
● Special Ceramic Raw Material: Used as a sintering additive for spark plugs, ceramic cutting tools and electronic substrates (e.g. integrated circuit substrates).
● Refractory Binder: Applied as a micropowder additive in castables and plastics to enhance medium and high-temperature strength.
● Coating Materials: Used in plasma spraying to produce wear-resistant and high-temperature-resistant coatings (e.g. for aero-engine component protection).
Cross & Emerging Applications
● New Energy Industry: Used in ceramic coatings for lithium battery separators (improving safety) and solid electrolyte matrices.
● Environmental Protection: Serves as adsorbent or membrane material component for wastewater and waste gas treatment.
● Advanced Manufacturing: 3D printing (e.g. photocurable ceramic printing) to produce ceramic parts with complex structures.
The high-performance properties of these materials make them irreplaceable in demanding industrial scenarios. With technological advancements, their application scope is continuously expanding to cutting-edge fields such as new energy and environmental protection.
