Ultra-Sol® 1000HP

High Purity Cerium Oxide Suspension

Ultra-Sol 1000HP is an extremely high purity, stable, precision cerium oxide polishing slurry used extensively for achieving sub-angstrom optical finishes on silica-based optical materials.  Polishing performance meets or exceeds industry specifications for sleek, scratch/dig, and surface finish.  The controlled particle distribution helps to eliminate sub-surface work damage caused by errant large particles.

With a purity of 99%, Ultra-Sol 1000HP utilizes the highest quality ceria abrasive available on the market.  It is ideal in demanding applications where impurities, such as thoria, cannot be tolerated.

Ultra-Sol 1000HP incorporates advanced particle suspension chemistry, simplifying the preparation, mixing, and distribution of the slurry in production.

Handling Instructions

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.

If the slurry is to be used in a diluted form, 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, the diluted slurry should be routinely mixed and filtered.

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.
