What This Product Is

Polycrystalline diamond suspension is a liquid diamond abrasive used during metallographic polishing to refine specimen surfaces after grinding. It contains polycrystalline diamond particles dispersed in a carrier fluid, allowing controlled material removal during intermediate and fine polishing steps.

Polycrystalline diamond abrasives are characterized by their tendency to fracture during use, which helps maintain consistent cutting action throughout the polishing process.

Intended Use in Metallography

This product is intended for intermediate to fine polishing steps , following planar or fine grinding. It is used to remove residual grinding damage, reduce surface scratches, and prepare samples for final polishing or microscopic examination.

Polycrystalline diamond suspension is commonly selected when:

• Consistent cutting behavior is needed across the polishing step
