Final Polishing Suspension

Final polishing suspensions are designed to remove the final layer of surface deformation and prepare a sample for analysis. Deformities may not be visible to the naked eye, but must be removed for some specimen analysis techniques.

A variety of alumina and silica products are offered by Buehler including colloidal silica polishing suspension to meet many different application needs.

Refer to the Ordering tab below to find the right final polishing suspension or powder for your application.

Excellent Surface Finish

  • Final polishing suspensions remove the final layer of surface deformation that may be left after diamond polishing. While this deformation is often invisible to the naked eye, it must be removed for some analysis techniques.

Application Specific Solutions

  • Alumina suspensions and powders along with colloidal silica suspensions offer a solution for the wide variety of materials being processed in today’s world.
