Monitoring the Stability of Colloidal Silica Solutions Over Time using the SZ-100V2

Particle Characterization

Colloidal silica is utilized in a wide range of industries, including masonry, textiles, paints, fining agents, and semiconductor manufacturing processes such as chemical mechanical planarization (CMP). Due to its broad applications, monitoring the stability of colloidal silica over time is essential for consistent performance. The HORIBA SZ-100V2 nanoparticle analyzer is a powerful tool for characterizing colloidal suspensions, providing measurements of particle size and zeta potential.

In this application note, we used the SZ-100V2 to evaluate the stability of LUDOX® TM-50, a colloidal silica slurry. Two samples were analyzed: one from a newly opened bottle ("Fresh LUDOX®") and one from a bottle that had been opened and stored for over a year ("Aged LUDOX®"). By measuring and comparing the zeta potential and particle size of these samples, we demonstrate how the SZ-100V2 can effectively monitor the stability of colloidal silica.
