Colloidal Silica for Sapphire, Silicon Carbide, and Hard Substrates
Ultra-Sol S17 was originally developed for critical sapphire slurry polishing processes where substrates were being sent to EPI processes. It has been proven to be just as effective in polishing other hard substrates, such as silicon carbide, when a low roughness surface finish is required.
The unique colloidal silica based formulation of Ultra-Sol S17 performs well in slurry recirculation systems due to the robustness of the particle, making it a perfect choice for all types of manufacturing environments.

This material is a safe, aqueous based slurry. To avoid skin or eye irritation, however, handlers should use appropriate personal protective equipment including: rubber gloves, protective clothing, and eye protection. Follow all MSDS, Safety Data Sheet, and label precautions when handling this slurry. Also follow all appropriate industrial safety and hygiene practices when handling or using this product.
This slurry is designed to be used straight, especially for hard substrates. However, it can be diluted if needed. When diluting, Eminess recommends using only high quality deionized water (>18 M ohm) for the dilution. The product should be mixed periodically (10 to 20 minutes per day) by recirculation or mechanical stirring to ensure that the particles are uniformly suspended. To avoid possible scratching issues, storage and re-use of on-site diluted slurry is not recommended without proper mixing and filtration.
Due to the unique formulation of this slurry, it is recommended that the user not adjust the pH. If a different pH is required, please contact your Eminess Applications Engineer for assistance with your specific process need.
It is recommended that products be stored up to the expiration date at temperatures between 4°C and 33°C (40°F and 90°F). Products can be stored if kept above freezing (0°C or 32°F), and kept below 38°C (100°F) if prolonged exposure at temperatures at either extreme are avoided. Storage outside of the recommended conditions may result in irreversible product damage. In the event of exposure outside of the recommended conditions, please contact your Eminess representative for recommendations. In all cases the products should be allowed to return to room temperature prior to use.
Dispose of in accordance with all applicable national and local regulations.
