Colloidal Silica / Alumina Suspensions

Used for final polishing, colloidal suspensions are mixtures of abrasive particles dispersed throughout a chemically aggressive liquid carrier. This combination provides a chemical-mechanical polishing action, resulting in deformation-free surfaces.

0.04 µm Non-Stick/Rinsable Colloidal Silica

Closer View

An excellent final polishing suspension for most materials, this proprietary formula features a pH of 10.5 and rinses easily from samples and equipment, even after it dries. It is slow-drying, making it an ideal choice for prolonged polishing requirements such as those for EBSD. The pH may be modified with chemical solutions to improve microstructural contrast.
