Polycrystalline Diamond Compound

Compatibility and Equivalents

Formulated for the same intermediate and fine polishing steps as these brand products:

• Buehler — MetaDi polycrystalline diamond paste
• Struers — DP-Paste P
• Allied High Tech — polycrystalline diamond compound

Runs on Buehler, Struers, LECO, Allied, and PACE systems with no change to your process. It is a comparable product for the same step — not a branded or drop-in item.

Same grading and micron sizing, typically 20–40% less.

Polycrystalline Diamond surpasses both synthetic and natural monocrystalline diamond for achieving superior surface finishes and higher removal rates in metallographic specimen preparation.

With numerous cutting surfaces per particle and a self-sharpening nature, polycrystalline diamond ensures faster material removal and finer finishes compared to monocrystalline diamond.

Its blocky shape, hexagonal microcrystallites, and absence of cleavage planes eliminate the risk of splintering, reduce sub-surface deformation, and enable efficient polishing of samples with varying materials and hardness levels.

Additionally, polycrystalline diamond boasts a very uniform surface finish, a more uniform particle size distribution, and an extremely rough surface with increased cutting points, further enhancing its effectiveness.
