PLDM-Polycrystalline Diamond Powder
Description: Produced through detonation synthesis, this polycrystalline diamond micron powder features a micro-granular structure without cleavage planes. It offers exceptionally high toughness, approximately three times that of monocrystalline diamond, allowing it to withstand extreme polishing pressure. The rough, multi-contact particle surface enhances cutting efficiency and material removal. Available in sizes from 0.25 to 10 μm.
What is PLDM？
PLDM (Polycrystalline Diamond Micron Powder) is composed of micro-fragmented, randomly oriented nanocrystals, formed via detonation synthesis. This structure results in high toughness and a unique self-sharpening effect during use. Its irregular particle morphology and rough surface provide more contact points between diamond particles and the workpiece, significantly increasing cutting and polishing efficiency. It is engineered for demanding processes requiring consistency, precision, and high-performance results.
Advantages of PLDM
- Fine Particle Size Range: Optimised for high-precision surface finishing.
- Rough Particle Surface: Increases contact area and enhances grinding action.
- Self-Sharpening Capability: Delivers consistent performance through micro-fracturing.
- High Toughness: Withstands greater working pressure than monocrystalline diamond.
- High Purity: Minimises contamination during sensitive polishing applications.
Typical Processing Applications
Production: Ideal for formulating high-performance polishing pastes, slurries, and precision-grade bonded tools used in demanding surface finishing processes.
- Sapphire Polishing: Precision finishing of synthetic sapphire components.
- Gemstone Processing: High-efficiency grinding and polishing of gems.
- Advanced Ceramics: Polishing of hard and brittle ceramic substrates.
- Tungsten Carbide: Fine finishing of carbide cutting tools and components.
- Composite and Soft/Hard Metal Polishing: Used in applications where uniform removal and surface quality are critical.
