Diamond Slurry for Precision Polishing and Lapping
Crownkyn diamond slurry, also known as diamond suspension, is a liquid abrasive formulation containing controlled diamond particles dispersed in a carrier system for precision lapping, polishing and surface finishing.
Available with monocrystalline, polycrystalline, agglomerated and nano diamond options. Particle size, concentration, viscosity and carrier system can be customized according to material requirements, equipment conditions and target surface finish.
What Is Diamond Slurry?
Diamond slurry, also known as diamond suspension, is a liquid abrasive formulation containing precisely controlled diamond particles dispersed in a carrier system. It is designed for lapping, polishing and precision surface finishing of hard materials.
The performance of diamond slurry depends on diamond type, particle size, concentration, carrier system and formulation stability. These parameters are selected according to the workpiece material, polishing process and required surface finish.
Crownkyn supplies customized diamond slurry formulations with different diamond grades, particle sizes and carrier systems for precision polishing applications.
Diamond Slurry Formulations by Diamond Type
Crownkyn supplies monocrystalline, polycrystalline, agglomerated and nano diamond slurry formulations for varied removal rates, surface finishes and polishing processes.
Monocrystalline Diamond Slurry
General Polishing GradeMonocrystalline diamond slurry uses strong single-crystal particles with defined cutting edges for efficient material removal and repeatable polishing of hard and brittle materials.
Polycrystalline Diamond Slurry
Fine Finishing GradePolycrystalline diamond slurry uses multi-edged particles with controlled micro-fracture to renew cutting points, reduce scratch depth and provide a finer, more uniform surface finish.
Agglomerated Diamond Slurry
Controlled Release GradeAgglomerated diamond slurry contains engineered diamond clusters that progressively release fine abrasive particles, supporting stable polishing action and consistent finishing performance.
Nano Diamond Slurry
Ultra-Fine Polishing GradeNano diamond slurry contains ultra-fine diamond particles formulated for final polishing stages requiring very low surface roughness, fine dispersion and minimal surface damage.
Key Factors in Selecting Diamond Slurry
Diamond slurry selection depends on material, polishing goal and formulation. The right combination provides stable removal, controlled scratching and consistent quality.

Common questions about diamond slurry, diamond suspension, abrasive selection and customized formulations.
What is diamond slurry? +
Diamond slurry, also called diamond suspension, is a liquid abrasive formulation containing diamond particles dispersed in a carrier system. It is used for precision lapping, polishing and CMP processes where controlled material removal and surface quality are required.
What is the difference between diamond slurry and diamond paste? +
Diamond slurry is a low-viscosity liquid formulation designed for lapping machines, automated dispensing and CMP applications. Diamond paste is a higher-viscosity formulation mainly used for manual polishing of molds, dies and precision components. The selection depends on equipment, workpiece geometry and polishing requirements.
What diamond types are used in diamond slurry? +
Diamond slurry can use different diamond abrasive types according to polishing requirements:
- Monocrystalline diamond: Consistent cutting performance for general precision polishing.
- Polycrystalline diamond: Controlled fracture behavior for fine finishing and reduced scratch risk.
- Agglomerated diamond: Controlled abrasive release for advanced slurry applications.
- Nano diamond: Used for ultra-fine polishing and specialty surface applications.
How to choose diamond particle size for polishing? +
Diamond particle size should be selected according to material hardness, required removal rate and target surface finish. Larger particles generally provide higher removal efficiency, while smaller particles reduce scratch depth and are used for fine or final polishing. Many processes use a step-down sequence from coarse to fine particle sizes.
Can Crownkyn customize diamond slurry formulations? +
Yes. Crownkyn can customize diamond slurry formulations according to your polishing process. Customization options include diamond type, particle size, concentration, carrier system and viscosity. Our technical team can recommend a suitable formulation based on your material, equipment and surface finish requirements.
