In critical applications such as precision investment casting, high-end coatings, electronic polishing, and catalyst supports, impurity control and particle size distribution stability directly determine the ultimate product quality. As a professional silica sol manufacturer, we understand your demand for nanometer-level precision. Today, we proudly present the IOTA Ammonium Silica Sol Series—a premium product defined by high purity, ultra-low sodium content, and narrow particle size distribution, providing a solid foundation for your product performance from the source.

Ammonium-Stabilized, Purity by Design
Our IOTA Ammonium Silica Sol features a unique ammonium stabilization system with Na₂O content ≤0.1%, significantly lower than conventional sodium-type silica sols. This makes it ideal for applications sensitive to metal ions—whether in precision casting face coats or semiconductor wafer polishing slurries, the low sodium content effectively prevents ionic contamination, ensuring process yield and product reliability.

Precise Particle Sizes, Tailored to Your Needs
We offer a gradient of particle sizes from 6nm to 30nm to meet diverse application requirements:

• AM3005 (6-9nm): Fine particle size, high specific surface area—ideal for precision polishing and thin-film coatings;

• AM3010 (10-15nm): General-purpose grade, balancing permeability with film-forming density;

• AM4010 (10-15nm, 40% high solid content): High concentration for improved coating efficiency and bonding strength;

• AM4020 (20-30nm, 40% high solid content): Larger particle size for filler reinforcement and anti-settling systems.

High Solid Content, Long Shelf Life, Consistent Quality
Solid content is available at 30% and 40% to meet various process concentration requirements. The mild alkaline system with pH 8-9 ensures compatibility with most water-based systems. With a shelf life of ≥12 months, product stability is time-tested and reliable.

From precision casting ceramic shell molds and refractory binders, to waterborne coating reinforcement, paper coating, and catalyst supports—IOTA Ammonium Silica Sol, with its intrinsic chemical purity and precise physical properties, is your ideal partner for enhancing product competitiveness. Choose IOTA—choose quality as the foundation of long-term success.
