Pace Technologies, GPC-1045-5L, 5-Liter Low Viscosity Polycrystalline Dia-mond Suspension, Automated Dispensing, 45 Micron
Feature:
- Recommended for manual dispensing
- Higher cutting rates
- Very uniform surface finish
- More uniform particle size distribution
- Higher removal rates (self-sharpening abrasives)
- Harder/tougher particles
- Blocky shaped
- Hexagonal microcrystallites (equally hard in all directions)
- Extremely rough surface (more cutting points)
- Surface area 300% greater than monocrystalline dia-mond
- No abrasion-resistant directionality (abrasion independent of particle orientation)
The majority of specimens will use at least one if not multiple, dia-mond polishing steps. For metallographic specimen preparation, either a man-made synthetic polycrystalline dia-mond or a monocrystalline dia-mond is used and the dia-mond is either mixed into a suspending solution or is used in a paste form. Dia-mond is the hardest known material (Mohs 10, 8000 HV). It has a cubic crystal structure. For metallographic applications, both monocrystalline and polycrystalline dia-mond can be used, however, polycrystalline dia-mond has a number of advantages over monocrystalline dia-mond, especially for the finer particle sizes.
