Slurry Product Line — Full Specifications
Monocrystalline Diamond Slurry
Monocrystalline diamond slurry for lapping and polishing hard materials — sapphire, technical ceramics, tungsten carbide and hardened steels. Blocky crystal shape delivers high, predictable cut rates while dispersion control keeps scratch depth uniform across the batch.
| Grades (µm) | 6, 4, 3, 2, 1, 1/2, 1/4, 1/6, 1/10 µm — MD-6 to MD-N100 |
| Model suffix | -W water-based / -O oil-based (e.g. MD-3-W, MD-3-O) |
| Rough-surface line (RCD) | 17, 10, 6, 5, 4, 3 µm — RC-17 to RC-3, for high removal rate lapping |
| Abrasive | Monocrystalline diamond |
| Carrier | Water-based or oil-based |
| Supply | Ready-to-use or concentrate |
| Packaging | Bottles to bulk |
| Typical applications | Sapphire, ceramics, carbide, metallography |
Polycrystalline Diamond Slurry
Polycrystalline diamond slurry whose multi-faceted crystals self-sharpen during polish — finer finishes at equivalent removal rates, preferred for wafer back-side polish, optics and finish-critical metallographic preparation.
| Grades (µm) | 6, 4, 3, 2, 1, 1/2, 1/4, 1/5, 1/10, 1/20 µm — PC-6 to PC-N50 |
| Model suffix | -W water-based / -O oil-based (e.g. PC-3-W, PC-3-O) |
| Abrasive source | PCD powder produced in-house, synthesized by explosive method |
| Abrasive | Polycrystalline diamond |
| Carrier | Water-based or oil-based |
| Supply | Ready-to-use or concentrate |
| Packaging | Bottles to bulk |
| Typical applications | Wafer polish, optics, metallography |
Nano Diamond Slurry & Suspensions
Nano diamond slurry and diamond suspension for the final, haze-removing polish step on fiber optic connector endfaces, precision optics and semiconductor components. Agglomeration-controlled dispersion protects the surface you just spent hours building.
| Grades (µm) | 1/4, 1/5, 1/6, 1/10, 1/20, 1/30 µm — DND-250 to DND-30 |
| Model suffix | -W water-based / -O oil-based (e.g. DND-100-W, DND-100-O) |
| Surface finish | Designed to achieve workpiece surface roughness of 0.2 nm or less |
| Abrasive | Nano diamond |
| Dispersion | Agglomeration-controlled, water-based |
| Supply | Ready-to-use or concentrate |
| Packaging | Bottles, bulk |
| Typical applications | Final polish: optics, connectors, semiconductors |
CMP Slurry & Oxide Polishing Suspensions
CMP slurry plus silicon carbide, aluminum oxide and cerium oxide polishing suspensions for chemical-mechanical planarization, optical glass and display panel finishing. Formulations tuned in-house — tell us your substrate, pad and target removal rate.
| Models | SOQ-12D · SO-100-PF · SO-80-PF · SO-60-PF · SO-40-PF · SO-20-PF |
| Particle size | 10–30 / 30–50 / 50–70 / 70–90 / 90–110 nm, spherical colloidal silica |
| pH | 10.5 ± 0.5 |
| Viscosity | <10 cst (SO-20-PF <30 cst) |
| Concentration | 20–50% (SO-20-PF 10–40%) |
| Package | 5 kg / 20 kg |
| Types | CMP slurry, SiC / AO / CeO₂ suspensions |
| Carrier | Water-based |
| Customization | Particle size, concentration, formulation |
| Packaging | Bottles to bulk |
| Typical applications | CMP, optical glass, LCD panel, wafers |
All slurries formulated and batch-tested in-house. Custom particle size, concentration and carrier formulations developed against your process window.
A Real Factory, Not a Trading Company
GRISH has manufactured precision abrasives since 2002 in a 12,000 m² factory & laboratory with imported coating and converting equipment. Over 20 years of joint R&D with universities turned research projects into 49 invention patents — and GRISH co-authored 5 industry standards for polishing materials. Slurries are formulated, blended and batch-tested in-house, so dispersion stability and lead time stay under our control, not a middleman’s.
- ISO9001 quality command across man, machine, material, method & environment
- Imported production equipment · 100+ technicians, half with 5–10 years tenure
- 20+ years university joint R&D · 49 patents · 5 industry standards co-authored
- 3,000+ customers, 9,000+ polishing solutions across 12 industries
Certified: ISO 9001 quality · ISO 14001 environmental · ISO 45001 occupational safety
