Powders and Suspensions

Superior control, down to the crystal

Our A, B and C polishing powders are developed to meet your most demanding requirements and offer a wide range of application versatility. They are developed through our special alum calcination process and offer purities of up to 99.999%. Stringent control during calcination results in uniform morphologies and consistent-sized crystals without sharp, angular edges that can scratch surfaces. The process also allows for excellent control over the Alpha/Gamma conversion for the production of a wide variety of powder grades with unique crystal sizes, particle distributions and performance characteristics.

Our typical A, B, and C alumina powders are also available in suspension form for lapping and polishing applications. These suspensions are stable, ready-to-use and water-based for easy cleanup.
