Diamond Powder As A Ceramic And Coating Additive
What This Process Needs To Solve
Used as an additive, diamond is a functional filler rather than an abrasive. Dispersed in a water-based ceramic or polymer coating it raises scratch and wear resistance; added to a ceramic feedstock it modifies how the part machines or prints. What matters is that the powder disperses evenly and does not change the colour or the chemistry of the host material.
Colour and purity
Coating customers often specify appearance as well as performance: a light grey powder leaves a water-based coating visually unchanged, where a darker grade would tint it. Purity matters too, because an additive stays in the finished product. Metal content that would be acceptable in a lapping sludge is not acceptable in a cured coating.
Ceramic machining and printing
Ceramic filters and structural parts are finished with micron diamond before and after firing, and ceramic feedstocks for 3D printing take fine diamond as a reinforcement. Both need a narrow distribution so the part finishes evenly and no single particle shows through.
Recommended Grades And Size Ranges
Additive grades are quoted by size, colour and purity. Where a coating has an appearance requirement, tell us the host colour.
| Use | Recommended grade | Size range | Why this grade |
|---|---|---|---|
| CoatingsWater-based ceramic and polymer systems | |||
| Wear-resistant water-based coating | HDY monocrystalline micron, light grey | 1 – 3 µm | Disperses evenly and does not tint the coating |
| Scratch-resistant polymer coating | HDY monocrystalline micron | 1 – 3 µm | Raises surface hardness without clouding |
| Ceramic parts and feedstocksFilters, structural ceramics, ceramic printing | |||
| Ceramic filter machining | HDY monocrystalline micron | 2 µm | Narrow distribution gives an even finish |
| Ceramic additive and 3D printing | HDY monocrystalline micron | 2 µm | Uniform reinforcement in the feedstock |
| Pre-fire finishing | HDY monocrystalline micron | 1 – 3 µm | Cuts green ceramic without pull-out |
We can supply the lightest available fraction and a sample for a trial batch where appearance is specified.
What has to hold
- Even dispersion in water-based systems
- Light grey appearance
- High purity, low metal content
- Narrow particle size distribution
- No agglomerates that would show as specks
