Cell Lab ZAL-27 Light Density Sintered Zirconia-Alumina Composite Beads — 25 kg

Cell Lab ZAL-27 Light Density Sintered Zirconia-Alumina Composite Beads — 25 kg

Durable, low-wear, light-density ceramic beads ideal to substitute glass media and improve grinding efficiency in planetary, stirred, bead, and dispersion mills.

Key Features

• Light density sintered composite beads combining zirconia and alumina, yielding improved breakage resistance and toughness.

• Bulk density ~ 1.7 kg/L, solid density around 2.65-2.85 g/cc.

• Hardness ~ 793 Hv10, Mohs hardness ≈ 8; glossy white finish.

• Wide size range by SKU: from 0.40-0.80 mm up to 5.00-6.00 mm.

SKU & Size Variants

Performance & Application Notes

• Excellent price-performance ratio among low-to-medium density grinding media.

• Smooth bead surfaces reduce wear on mill internal components (liners, jar walls).

• Can replace glass beads in many milling/dispersion operations to improve efficiency and reduce media attrition.

• Size selection: finer beads (≤1.50 mm) for pigment, inks, coatings; coarser (≥3.00 mm) for general grinding, pre-grind, feed material reduction.

FAQ

Q1: What is ZAL-27 best used for vs glass beads?
A: Use ZAL-27 when you need more wear resistance and higher grinding speed than glass, but still want lighter, lower cost ceramic media.

Q2: How to choose SKU size?
A: Match bead size to your jar or mill volume and target particle size. Smaller sizes (≤ 1.20 mm) for fine dispersion; larger sizes (≥ 3.00 mm) for coarse grinding.

Q3: Is there heat or contamination concern?
A: Ceramic beads are chemically stable; heat buildup is lower than metal media but still monitor temperature on long runs.

Q4: How many beads per liter of jar volume to use?
A: Recommended bead + sample fill ≤ 2/3 of jar internal volume. Ensure bead mass is sufficient for impact energy without overloading.

Q5: Can ZAL-27 beads be used for both wet and dry milling?
A: Yes. Ensure proper sealing in wet systems and avoid stagnant liquid contact. For dry milling, avoid overheating.
