Zircon, or zirconium silicate, is another less common abrasive used for coarse grinding. It is a very tough abrasive, so it lasts longer, however it is generally not as hard or sharp, and thus requires higher pressures to be effective.
Colloidal silica, with a grain size of approximately 0.04 µm and a pH of about 9.8, has shown remarkable results. The combination of chemical activity and fine, gentle abrasion produces scratch-free and deformation-free specimens. Lapping In lapping, the abrasive is applied in a suspension onto a hard surface.
