Technical Insight

Particle Size & Milling Logic

Understanding how particle size affects your glaze performance — and why controlled milling matters.

Why Particle Size Matters

The particle size of zirconium silicate directly influences opacity, surface smoothness, and glaze behavior. Finer particles provide higher opacity but may affect suspension; coarser particles offer better flow but reduced covering power. Selecting the right D50 is essential for achieving your desired glaze results.

Fine Particle (D50: 1–3 μm)

Maximum opacity and whiteness
Excellent for high-gloss glazes
Ideal for thin glaze layers

Best for: Premium tableware, high-end tiles

Medium Particle (D50: 3–5 μm)

Balanced opacity and flow
Good suspension stability
Versatile application range

Best for: General ceramic glazes, sanitaryware

Coarse Particle (D50: 5–10 μm)

Better flow characteristics
Reduced settling issues
Cost-effective coverage

Best for: Ceramic bodies, industrial applications

Our Milling & Classification Approach

Precision Milling Control

Advanced milling equipment ensures narrow particle size distribution, minimizing oversized and undersized particles that affect glaze consistency.

Multi-Stage Classification

Air classification technology separates particles precisely, allowing us to achieve target D50 values with tight tolerances.

Batch-to-Batch Consistency

Every batch undergoes laser particle size analysis to ensure your production receives material with identical characteristics.

Selection Guide

How to Choose the Right Grade

Match your application requirements with the optimal zirconium silicate specification.

If Opacity Is Your Priority

You need maximum covering power with minimal material usage.

Recommended Focus:

Finer particle size (D50: 1–3 μm)
Higher ZrO₂ content (65%+)
Narrow particle size distribution

If Glaze Smoothness Matters

You want a defect-free, silky surface finish on your products.

Recommended Focus:

Medium particle size (D50: 3–5 μm)
Low oversize particle content
Controlled impurity levels

If Cost-Efficiency Is Key

You need reliable performance at competitive pricing.

Recommended Focus:

Standard particle size (D50: 4–6 μm)
Standard ZrO₂ content (63–65%)
Larger order quantities for better pricing

Common Selection Mistakes to Avoid

Choosing the finest particle without considering suspension

Ultra-fine particles may settle quickly in glaze slurry, causing inconsistent application.

Ignoring impurity levels for white glazes

Even small amounts of Fe₂O₃ can cause yellowing in high-temperature firing.

Switching suppliers without trial testing

Different processing methods can produce materials with the same specs but different performance.
