About Henan Yumo New Materials Co., Ltd.

Henan Yumo New Materials Co., Ltd. is a leading Chinese manufacturer of high-performance abrasives, specializing in White Fused Alumina, Brown Fused Alumina, Black Silicon Carbide, and Green Silicon Carbide (Green SiC). With three vertically integrated production facilities in Henan Province, we leverage advanced smelting, crushing, and precision classification technologies to deliver over 60,000 metric tons annually. Our commitment to sustainable manufacturing, stringent quality control, and global standards (FEPA, JIS, GB) positions us as a trusted partner for industries requiring ultra-reliable abrasive solutions3813.

Why Choose Green Silicon Carbide?

Green Silicon Carbide (SiC) is a synthetic abrasive produced at temperatures exceeding 2,000°C in electric resistance furnaces using premium raw materials:

• High-Purity Quartz Sand (>99% SiO₂)

• Low-Ash Petroleum Coke

• Sustainable Wood Chips

• Salt Additives (critical for crystal formation)34.

Distinguished by its emerald-green color and extreme hardness (Mohs 9.2–9.3, Knoop 2,840–3,320 kg/mm²), Green SiC outperforms conventional abrasives like alumina in precision grinding, cutting, and surface finishing applications. Its splintering friability ensures continuous self-sharpening, while its chemical inertness guarantees stability in corrosive environments3413.

Technical Specifications & Grades

1. Chemical Composition

• SiC Content: 97.5%–99.5% (adjustable per application)

• Free Carbon (F.C): ≤0.20%–0.35%

• Iron Oxide (Fe₂O₃): ≤0.20%–0.35%

• Trace Elements: Controlled sulfur, calcium, and alumina levels34.

2. Particle Size Ranges

• Coarse Grits: F12–F90 (12#–90#) for heavy material removal

• Medium Grits: F100–F240 (100#–240#) for general grinding

• Fine Micropowders: F280–F2000 (280#–2000#) for polishing and lapping

• Custom Sizing: Tailored cuts for refractory grains (0–1mm, 1–3mm), PV silver pastes, or wire sawing slurries3913.

3. Performance Advantages

• Thermal Conductivity: 100 W/m-K – prevents workpiece burning

• Thermal Shock Resistance: Low expansion coefficient maintains integrity at 1,600°C+

• Blocky Crystal Structure: Enhances cutting aggression and recyclability813.

Industrial Applications

✅ Precision Machining & Surface Treatment

• Semiconductor & Solar Wafer Processing: GC 600#–3000# micropowders enable damage-free slicing of silicon ingots and aluminum nitride ceramics13.

• Metal Alloy Grinding: Ideal for non-ferrous metals (brass, aluminum), cast iron, and titanium due to low heat generation313.

✅ Abrasive Tool Manufacturing

• Bonded Abrasives: Vitrified grinding wheels, honing stones

• Coated Abrasives: Sandpaper, abrasive belts (P-series for uniform grain distribution)14.

✅ Advanced Refractories & Ceramics

• Kiln Furniture: Saggers, setters with high creep resistance

• Steelmaking Deoxidizers: Accelerates slag formation and extends furnace lifespan813.

✅ Functional Additives

• Photovoltaic Silver Paste: GC 3000# powder improves conductivity and weather resistance in PV cells1.

• Anti-Slip Coatings: High-traction surfaces for marine decks and industrial flooring13.
