Low-sodium aluminum oxide, stable performance.

Our White Fused Alumina was recently tested by SGS, with Na₂O content controlled below 0.1%.

For refractory, blasting, polishing, and ceramic applications, lower sodium content can help improve high-temperature stability, reduce impurity influence, and support more consistent performance during use.

From raw material selection to smelting and screening control, we continue focusing on stable quality rather than only price.

Reliable materials create reliable products.

🔍 Overseas Market Observation | White Fused Alumina

In recent years, White Fused Alumina (WFA) has been gaining increasing attention across the refractory, abrasive, and surface treatment industries.

Compared with traditional Brown Fused Alumina, more customers are seeking solutions that combine:

✔ Higher purity
✔ Better thermal stability
✔ Cleaner blasting performance
✔ More stable particle sizing
✔ Improved consistency in continuous production

Particularly in refractory applications, WFA is gradually becoming a preferred option for customers pursuing both performance improvement and long-term cost optimization.

At the same time, global buyers are placing greater emphasis on:

• Stable supply capability
• Quality consistency between batches
• SGS/third-party inspection support
• Flexible customization for different applications

As a manufacturer focused on alumina materials, we continue to observe growing demand for WFA in refractory castables, precision blasting, wear-resistant ceramics, and polishing applications worldwide.

The market is no longer only about “lower price”, but increasingly about: “stable quality for sustainable production.”

🔥 Fused Mullite vs. Calcined Mullite — Which One Fits Your Application Better?

Both materials are widely used in the refractory and ceramic industries, but their production process and performance characteristics are quite different.

🔹 Fused Mullite
✔ Produced by high-temperature electric fusion
✔ Higher bulk density & lower porosity
✔ Excellent thermal shock resistance
✔ More stable crystal structure
✔ Ideal for high-end refractory and extreme temperature applications

🔸 Calcined Mullite
✔ Produced through sintering/calcination process
✔ More cost-effective solution
✔ Good thermal stability
✔ Suitable for conventional refractory applications
✔ Widely used where balanced performance and cost are required

📌 Choosing the right mullite is not only about price — it is about matching performance with your working conditions.

We supply both fused mullite and calcined mullite for refractory, kiln furniture, foundry, and ceramic applications.

When price meets performance.

With raw material costs declining, WFA is now priced even below BFA — without compromising performance.

Across abrasives • sandblasting • refractory industry, WFA is emerging as a new, smarter choice.

✔ Lower cost
✔ Higher purity
✔ Better stability

In many cases, it’s not just a replacement —
It’s a performance upgrade.

Storage Guidelines — White Fused Alumina

1. Keep dry
Use woven bags with PE inner liners
Store in a dry warehouse (recommended < 65% RH)
Avoid exposure to humid air

2. Seal tightly
Ensure inner liners are properly closed

3. Store off the ground
Use pallets, ≥10 cm above floor
Prevent direct contact with concrete surfaces

4. Keep a distance from the walls
Maintain space to avoid condensation zones
Ensure air circulation around the pallets

Proper storage is the first step to consistent performance.

A Small Technical Insight from a Downstream Application

A 5 W/m·K thermal conductive gel formulated with our alumina powder has been subjected to continuous thermal aging at 180°C since March 19.

After more than 800 hours of exposure, the material system remains stable, with no visible degradation observed:
– Sustained surface wettability
– Maintained soft and compliant structure
– No cracking or drying behavior

Under long-term thermal stress, subtle differences in raw materials begin to define performance stability. Website: www.zzyfml.com

Face Coat Material More Than You Think

In investment casting, the final surface isn’t an accident—it starts with the face coat material.

A stable face coat means:
✔ Smoother surface finish
✔ Better detail replication
✔ Reduced casting defects
✔ More consistent production
Our alumina solutions are designed for face coat performance:
👏 Fine, controlled particle size distribution
👏 Low impurity levels for cleaner surfaces
👏 Stable chemistry for repeatable results
From refractory to precision casting, we focus on one thing:
✨ Consistency that shows on every casting ✨ .

If surface quality is critical in your process, it may be time to review your face coat materials. Website: www.zzyfml.com
