Used for final polishing, colloidal suspensions are mixtures of abrasive particles dispersed throughout a chemically aggressive liquid carrier. This combination provides a chemical-mechanical polishing action, resulting in deformation-free surfaces. The modified pH of these suspensions can provide delineation of grain boundaries and other microstructural features for some sample types.
The 0.02 micron colloidal silica formula provides ultra-fine surface finishes for demanding SEM/TEM analysis. It is non-crystallizing and has a 9.8 pH.
The 0.05 micron colloidal silica formula is an excellent final polish for a wide variety of materials, especially non-ferrous metals, PCBs and ICs. It is non-crystallizing and has a 9.8 pH
