0-1mm Sintered Tabular Alumina Aggregate With Al₂O₃ ≥ 99.2%

Product Description

HUAO 0-1mm Tabular Alumina is an additive-free, premium sintered corundum aggregate precisely crushed and sized to a 0-1mm fraction. Fully sintered at ultra-high temperatures to achieve complete shrinkage, it features a dense, well-developed alpha-Al₂O₃ crystal structure with an Al₂O₃ content exceeding 99.2%. Engineered specifically as a foundational skeleton aggregate for high-performance refractory castables and shaped products, this 0-1mm fraction ensures optimal particle packing density and exceptional thermal performance.

Technical Parameters

Alternative particle size cuts can be precisely prepared according to customer requirements.

Key Features

• Screen and classify according to strict particle distribution standards to ensure consistent particle size and optimal matrix skeleton support.
• Fully sintered, free of fluxes such as MgO, maintaining high refractoriness.
• Features large, interlocking alpha-Al₂O₃ tabular crystals that provide superior mechanical toughness and structural integrity.
• Attains a bulk density of ≥ 3.50 g/cm³ alongside an apparent porosity of ≤ 5.0%, preventing corrosive penetration.

Advantages

• Exceptional Volume Stability: Exhibits minimal dimensional change after high-temperature firing, safeguarding refractory structures against thermal stress deformation.
• Optimized Matrix Fluidity & Packing: Regular grain shapes with minimal flake content improve castable flowability and packing density, resulting in denser final installations.
• Reduced Water and Binder Demand: Low water absorption rates significantly decrease mixing water requirements in castable formulas while lowering overall binder consumption.
• Superior Slag & Thermal Shock Resistance: Low apparent porosity and high purity levels drastically enhance resistance against aggressive steelmaking slags and severe temperature fluctuations.

Applications

As the main structural skeleton aggregate, 0-1mm particle size is widely used in high-performance integral castables, alumina magnesia carbon (AMC), magnesia carbon, and magnesia spinel bricks in the steel, casting, ceramic, and petrochemical industries. In addition, it plays a crucial role in the manufacturing of critical functional ceramics, such as blow plug cores, sliding door panels, continuous casting refractory materials, and induction furnace working linings, which are designed to extend service life and minimize wear.
