High Performance Characteristics: Particle Size, Consistency

LUDOX® colloidal silica products are aqueous dispersions of silica particles in the low nanometer size range that typically exhibit a narrow particle size distribution. Process design and control ensure quality and consistency. Combined with excellent purity and a wide range of options, these attributes make the LUDOX® colloidal silica family an excellent choice for many applications.

LUDOX® colloidal silica improves the performance of your products as inorganic binders, reinforcing and strengthening agents, refractory bonding agents, and sur​face modifiers. As a binder, it provides excellent strength and adhesion in catalyst washcoats and catalyst structures, precision investment casting molds, insulation boards, and other refractory fiber-based parts. It can also be used as a silica source in the manufacture of zeolites, as co-binders in functional coatings and as flocculating agents, and in paper manufacturing.

Cited in over 30,000 patents, applications for LUDOX® colloidal silicas are numerous and diverse. Researchers continue to discover new ways to use LUDOX® colloidal silicas in cutting-edge research, breaking ground for future scientific innovation and leading to potentially thousands more patents to come.
