A method for chemically stabilizing polishing slurries in aqueous suspension to prevent their agglomeration while maintaining their surface activity is disclosed. The method prevents the formation of irreversible particle agglomerates during drying and permits the subsequent re-suspension of dried particles with no impact on the particle size distribution. The stabilization method can be customized based on knowledge of the colloid surface charge at suspension pH conditions, addition of a charged species having like charge to the colloid at the suspension conditions, and control of the concentrations of the charged species and other ions in suspension.

Polishing slurry preventing agglomeration of charged colloids without loss of surface activity

A method for preventing damage caused by high intensity light sources to optical components includes annealing the optical component for a predetermined period. Another method includes etching the optical component in an etchant including fluoride and bi-fluoride ions. The method also includes ultrasonically agitating the etching solution during the process followed by rinsing of the optical component in a rinse bath.
