Ultra-Fine, Ultra-Precise: Wet-Milled Aluminas for Critical Industries

Almatis’ wet milling technology takes alumina performance to the next level, delivering powders that are finer, purer, and more versatile than ever before. By combining precision engineering with proven safety and compliance, we provide customers across industries with products that raise the bar in reliability and innovation.

Going Beyond Dry Milling

Dry milling is limited by the size of primary alumina crystals. With our advanced wet milling process, we can grind to the submicron level; the result: aluminas with higher specific surface area and tighter particle size distributions. For customers, this means greater reactivity, improved structural strength, and better control of viscosity, settling, and blending in their applications.

Cleaner Powders, Greater Safety

Every customer faces the challenge of removing metallic iron from feedstock. Our wet milling technology tackles this effectively, removing metallic iron particles in the wet phase, without compromising product purity. Safety is also integral to our operations: all processing and logistics comply with stringent requirements for hazardous materials, proven through years of successful handling. Customers can trust Almatis to deliver not just performance, but safe, consistent, and reliable supply.

Flexibility That Fits Customer Needs

Almatis applies advanced water- and solvent-based wet milling technology to engineer aluminas with the highest precision. This dual capability is rare in the industry and gives our customers a clear efficiency advantage. For solvent-based systems, for example, we can mill directly in the customer’s solvent of choice, eliminating unnecessary drying steps and streamlining their process. We also supply dry powders where required, ensuring full flexibility.

Customization is built into our approach: multiple additives can be integrated during milling, and milling media can be adjusted between zirconia (for strength) and alumina (for purity-critical applications). This flexibility enables Almatis to deliver tailor-made products that fit seamlessly into customer processes.

Enabling High-Tech Applications

Our wet-milled aluminas are shaping the future of ceramics, electronics, and energy. In ceramics, tighter particle size control enhances strength and reactivity. In electronics, ultra-fine powders function as high-performance fillers for thinner films and miniaturized components. In energy storage, the Ultra Series is opening new possibilities for EV battery separators, while the Ultimate Series is setting benchmarks in polishing.

With wet milling, Almatis offers beyond alumina. solutions that enable smaller, stronger, and smarter innovations across critical industries.
