The Power of Colloidal Silica

LUDOX® Colloidal Silica
Refractory Applications

Colloidal silica is an important industrial product that is manufactured from the simplest of ingredients, sand and water. However, its useful properties are far from commonplace. LUDOX® colloidal silicas are discrete, nanoscale, spherical particles of amorphous silica dispersed in water. In addition to being extremely durable, stable, and heat-tolerant, these particles can be tailor-made and chemically customized to yield enormous potential.

LUDOX® Colloidal Silicas in Refractory Insulation Applications

LUDOX® colloidal silica particles are routinely used as inorganic flocculants, binders and stiffeners for refractory fibers to produce high-temperature composites in diverse applications.
