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

Lapping and polishing of:
- sapphire
- synthetic gemstones
- ceramic oxides
- hard disk media texturing
- hard disk GMR heads
- fiberoptic components
- metalographic specimen
- composite materials
- tungsten carbide
- silicon carbide
- die castings
