Green sic powder #1200 polishing ceramic components

What green silicon carbide powder can be used for polishing ceramic components?

For sandblasting ceramic components, green SiC powder is the preferred choice because it perfectly matches the processing requirements of ceramics: hardness, brittleness, precision, and high cleanliness. It possesses sufficient hardness for cutting, controllable brittleness to prevent chipping, good thermal conductivity and heat dissipation, high purity with no impurities, uniform particle size, strong self-sharpening properties, and chemical stability, making it the “golden abrasive” for ceramic sandblasting.

Key specifications for ceramic polishing

1.Purity

≥98.5% or ≥99% Green SiC

Low iron, low free carbon, no heavy metal contamination →

Critical for electronic ceramics to avoid insulation failure.

2,Particle size (for polishing)

Coarse grinding: #240 – #600

Fine grinding: #800 – #1500

Polishing / Lapping: #2000 – #8000

Ultra‑precision polishing: W1.5 – W5 (micron grade)

3.Shape & performance

Sharp, angular particles → good cutting force

Self-sharpening → prevents chipping on brittle ceramics

High hardness (Mohs ~9.5) → harder than most ceramics

High thermal conductivity → avoids thermal damage during polishing
