Ultra-Sol® 1000

Cerium Oxide Polishing Slurry

Ultra-Sol 1000 is an exceptionally uniform cerium oxide dispersion used extensively for general purpose polishing of glass, quartz, fused silica, and other silica-based optical materials. The alkaline (pH 9) slurry is formulated to provide chemically enhanced polishing, high throughput, and excellent surface finish. Ultra-Sol 1000 performance exceeds industry specifications for sleek, scratch/dig, and surface finish. The controlled particle distribution helps to eliminate sub-surface damage caused by errant large particles. The unique chemistry allows for a uniform and permanent suspension of the abrasive, which provides consistent and repeatably superior surface finishes. The advanced particle suspension technology in the Ultra-Sol 1000 also creates an easy to use slurry in a production environment.

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.
