High-Purity White Fused Alumina with Fire Resistance 1850°C

High-Purity White Fused Alumina (WFA) for Abrasives and Refractories

Product Overview

HUAO White Fused Alumina (WFA) is a premium synthetic corundum produced by fusing high-purity calcined alumina powder in an electric arc furnace at extreme temperatures exceeding 2000°C. The resulting fusion yields a highly uniform alpha-Al₂O₃ crystalline structure characterized by high hardness (Mohs 9.0), excellent mechanical toughness, outstanding self-sharpening properties, and superior chemical stability. Designed for demanding B2B industrial applications, HUAO supplies two primary product categories: Abrasive Grade for high-precision surface blasting, grinding, and polishing, and Refractory Grade for severe-duty furnace linings and high-temperature castables.

Technical Specifications

Parameter / Size	Grade	Al₂O₃ (%)	Na₂O (%)	SiO₂ (%)	Fe₂O₃ (%)	Specific Gravity (g/cm³)	Fire Resistance (°C)	Density (g/cm³)	Apparent Porosity (%)
Particle (0-1, 1-3, 3-5, 5-8 mm)	Abrasive / Refractory	≥ 99.4	≤ 0.30	≤ 0.08	≤ 0.08	3.95	1850	3.6	7
Powder (200 mesh, 325 mesh)	Refractory / Fine	≥ 99.2	≤ 0.35	≤ 0.10	≤ 0.10	3.95	1850	3.6	7

Custom grain sizes and tailored particle size distributions can be prepared according to specific client requirements.

Applications

It is widely deployed in shaped bricks, monolithic castables, ladle linings, and tundish refractories across the steel, glass, and ceramics industries. Beyond refractory applications, its high purity and rapid cutting rates make it ideal for manufacturing bonded abrasives (such as grinding wheels), coated abrasives, sandblasting media, and precision polishing compounds engineered for zero iron contamination. Furthermore, it is seamlessly incorporated into high-wear ceramic tiles, kiln furniture, and burner blocks designed to withstand severe mechanical abrasion and extreme thermal cycling in cement and metallurgical plants.

Why Choose HUAO

Powered by advanced thermal processing, HUAO guarantees fully developed corundum crystal structures with minimal residual internal stresses and predictable batch-to-batch consistency. To match exact industrial formulation requirements, we supply precise sieve cuts ranging from coarse aggregate fractions (0-1 mm up to 5-8 mm) down to fine micro-powders (200 mesh and 325 mesh). Furthermore, backed by extensive international trade expertise, HUAO ensures seamless end-to-end execution—delivering factory-direct bulk supply, rigorous quality assurance, and comprehensive ocean shipment coordination.

Customization and Packaging

HUAO White Fused Alumina is available in standard aggregate fractions—including 0-1 mm, 1-3 mm, 3-5 mm, and 5-8 mm—as well as fine powder grades such as 200 mesh and 325 mesh, with fully customizable particle size distributions engineered upon request. To ensure cargo integrity during international transit, our standard export packaging features durable 25 kg multi-wall woven bags and heavy-duty 1,000 kg or 1,250 kg jumbo bags equipped with protective inner polyethylene moisture barriers. Furthermore, all shipments are professionally palletized, corner-protected, and tightly stretch-wrapped to withstand rigorous ocean freight, while fully supporting custom OEM labeling and flexible packaging specifications to seamlessly align with your facility's automated handling and branding requirements.

FAQ

1.Are HUAO manufacturing facilities certified under international quality management standards?

Yes, HUAO operates in full compliance with certified ISO 9001, ISO 14001, and ISO 45001 management systems, enforcing rigorous quality inspections on every batch.

2.What is the primary difference between Abrasive Grade and Refractory Grade WFA?

Abrasive Grade focuses on high purity (Al₂O₃ ≥ 99.4%) and grain toughness for sharp cutting efficiency, while Refractory Grade emphasizes high thermal stability, minimal sodium/iron impurities, and consistent grain packing for furnace linings.

3.What fire resistance and temperature limits does HUAO White Fused Alumina support?

HUAO White Fused Alumina features a fire resistance rating of 1850°C, making it suitable for high-temperature refractory applications subject to rapid thermal cycles.

4.Why is low Fe₂O₃ content critical in white fused alumina applications?

Low iron oxide (Fe₂O₃ ≤ 0.08%) prevents localized melting spots in high-temperature refractories and eliminates rust staining or metal contamination during abrasive sandblasting.

5.Can HUAO supply customized particle size distributions for specific customer requirements?

Yes, HUAO provides tailored crushing, screening, and air-classifying services to deliver custom grain sizes and fine powders matched to your exact formulation needs.
