Product Description

Product Introduction

Aluminum is an amphoteric substance, reactive with both acids and bases. It boasts an extremely high melting point, staying stable under intense heat. It also has multiple crystalline structures. Alpha - alumina is dense, hard, and durable, perfect for situations needing strength and wear resistance. Gamma - alumina has a large surface area, making it more chemically reactive, which is great for applications relying on reaction surfaces.

Product Application

1. Metallurgy Sector

• Aluminum Manufacturing: Alumina is the core raw material for aluminum production. Via electrolysis, it turns into pure aluminum, which is vital in aerospace (for lightweight parts), automotive (engine components), and packaging (foils/cans) because of its lightness, corrosion resistance, and conductivity.
• Refractory Solutions: Its heat - resistant nature makes it ideal for refractory products like bricks, crucibles, and furnace linings. In steel mills, alumina - based refractories endure molten steel and slag erosion, keeping furnaces running.

2. Chemical Industry Uses

• Catalyst Support: Gamma - alumina, with its porous, high - surface - area structure, holds catalysts in petroleum refining. It boosts reactions like cracking (breaking down heavy oils) and desulfurization (removing sulfur), making fuel cleaner and production more efficient.
• Purification Aid (Adsorbent): Alumina soaks up impurities from gases/liquids. In natural gas processing, it dries the gas and filters out acidic contaminants, ensuring pipeline safety and quality.

3. Electronics and Advanced Materials

• Semiconductor and Circuit Roles: In electronics, alumina acts as an insulator in integrated circuits (ICs), preventing short - circuits and enabling miniaturization. It also forms substrates for LED chips, helping with heat dissipation and stable light emission.
• Ceramic Innovations: Alumina - based ceramics are used in cutting tools (like drill bits) for their hardness, and in medical implants (joint replacements) because they're biocompatible and wear - resistant.

4. Daily Life and Specialty Uses

• Consumer Goods: In cosmetics, finely ground alumina works as an abrasive in toothpaste (polishing teeth) or a texture - enhancing filler in makeup.
• Energy Storage: Emerging uses include battery components. Alumina coatings can protect battery electrodes, improving lifespan and safety in electric vehicles and gadgets.
