Description

Application

This material is highly monodisperse in size and shape (<0.25 polydispersity index), and provides significantly improved surface reactivity. It is stable at high suspension densities, when utilized at the recommended pH range (3.0-4.0). Applications include emissions catalysis, oxidation catalysis, regeneration of particle traps in diesel engines, and use as a pigment.
