Green Silicon Carbide (SiC) Powder - 1000 Mesh - ZhenAn International
Precision manufacturing in the semiconductor, optical glass, and high-end ceramic sectors requires materials that offer both extreme hardness and chemical neutrality. Standard abrasives often fall short, causing surface defects or thermal stress during fine processing.
ZhenAn's 1000 Mesh Green Silicon Carbide (SiC) Powder is the ultimate solution for ultra-fine grinding and lapping. With a purity level exceeding 99%, our green SiC powder is specifically processed to ensure uniform particle shapes and a narrow size distribution, providing a flawless finish on the hardest surfaces.
Technical Specifications and Purity Levels
ZhenAn's Green SiC is produced using high-quality silica and petroleum coke with salt as an additive in a resistance furnace at temperatures above 2200°C.

Key Applications: From Semis to Super-Hard Materials
1. Semiconductor Wafer Lapping
Used in the slicing and lapping of monocrystalline silicon, gallium arsenide, and quartz crystals. The 1000-mesh grit ensures minimal subsurface damage.
2. Technical Ceramics (SSiC/RBSiC)
A primary raw material for high-performance ceramic seals, nozzles, and armor plates where high-density sintering is required.
3. Optical Glass & Gemstone Polishing
Ideal for the precision polishing of optical lenses, prisms, and hard gemstones that require a mirror-like finish without scratching.
4. Wire Sawing & Thermal Coatings
Acts as a high-performance heat-conducting filler in specialized coatings and as an abrasive in wire sawing for hard-to-cut materials.
The Production Process: Why 1000 Mesh Requires Precision
Achieving a consistent 1000 mesh (approx. 11.5 microns) requires advanced classification technology:
Smelting: High-purity raw materials are reacted in a large-scale electric furnace.
Crushing & Milling: The green SiC "crystal cake" is crushed and then air-jetted into fine powders.
Hydraulic Classification: Unlike coarse grit, 1000 mesh is separated using water-sedimentation or airflow centrifuges to ensure no "oversize" grains exist.
Acid/Alkali Washing: Removes any remaining metallic traces to ensure semiconductor-grade purity.
Green SiC vs. Black SiC: The Performance Gap
| Property | Green SiC (1000 Mesh) | Black SiC (1000 Mesh) |
| SiC Purity | 99% + | 97% – 98% |
| Hardness | Slightly Higher | High |
| Friability | More Brittle (Sharper) | Tougher |
| Application | Precision Optics, Semis, Hard Alloys | Cast Iron, Glass, Stone, Leather |
| Thermal Conductivity | Excellent | Good |
