DP
type micron diamond
Mypolex polycrystalline diamond, precision size range
Appearance
DP diamond is dark gray to black in color.
Particle structure
DP diamond is formed by explosion synthesis, leading to a polycrystalline
particle structure. Each diamond particle consists of countless
microcrystallites, about 20 nanometers in size. Polycrystalline
diamond features no cleavage planes, which makes the particles
tougher, compared to monocrystalline particles.
Characteristics
DP diamond is precision graded to tight specifications, making
it the preferred choice for high-quality, high-performance applications.
Due to the absence of cleavage planes, DP diamond is equally
hard and tough in all directions. This allows for higher process
pressures and thus increased material removal rates in lapping
and polishing applications.
The rough, micro-structured particle surface leads to higher
abrasion rates on both hard and soft materials. The typically
blocky and regular particle shape yields better polishing results
compared to equally-sized monocrystalline diamond.
Typical applications

- sapphire
- synthetic gemstones
- ceramic oxides
- hard disk media texturing
- hard disk GMR heads
- fiberoptic components
- metalographic specimen
- composite materials
- tungsten carbide
