Peanut-shaped Colloidal Silica

Peanut-shaped IDISIL® Colloidal Silica is suitable for applications where high aspect ratio morphology is favorable, e.g. CMP abrasives and foam nucleators. 

Peanut-shaped IDISIL® is characterized by its ultra-high purity and diverse possibilities for customized surface functionalization. Our robust production process leads to particles with high consistency and reproducibility. With our proprietary production process we can adjust particle sizes without comprimising quality.

Currently, our IDISIL® Colloidal Silica grades are in exploratory stage. Depending on the product, our production runs in small-, mid- or large-scale. Please let us know what your specific quantity requirements are, so that we can find a suitable solution for you.
