Product Description

Product DescriptionGreen Silicon Carbide for PolishingHenan Yumo New Materials' polishing-specific green silicon carbide micro powder is an ultrafine abrasive meticulously crafted to meet the demands of high-end precision surface treatment. Its particle size ranges from F400 (17 μm) to F2000 (3 μm) and even finer submicron levels. With its extremely high purity, sharp micro-edges, precise particle size control, and excellent chemical stability, it is an ideal choice for achieving ultra-smooth, damage-free surfaces, and is widely used in the final polishing processes of optical, semiconductor, precision ceramic, and high-end metal workpieces.Specification

Key Characteristics & Advantages
Characteristic Dimension	Detailed Description	Value Created for Customers
Exceptional Hardness & Nano-scale Cutting Ability	Mohs hardness of 9.2–9.3 combined with sub-micron sharp edges enables atomic-level material removal.	Achieves ultra-low surface roughness (Ra < 0.01 μm) with mirror-like finish, meeting the highest optical and surface finish requirements.
Excellent Chemical Stability	Resistant to acids and alkalis; does not react with common polishing fluid media.	Contamination-free polishing process without introducing chemical impurities, preserving the intrinsic properties of the workpiece—ideal for semiconductor and optical applications.
Precise Particle Size Distribution	Utilizes multi-stage hydraulic classification with extremely narrow distribution (Span < 0.8) and no oversized particles.	Provides uniform, scratch-free polishing with predictable and repeatable material removal rates, improving product yield.
High Purity & Low Impurities	SiC ≥ 99%, Fe2O3 ≤ 0.08%, and extremely low metal impurity content.	Eliminates surface contamination, preventing ionic contamination or discoloration when polishing silicon wafers, sapphire, and precision alloys.
Good Dispersion Stability	Uniform particle morphology; dispersion in oil-based/water-based systems can be further optimized via surface treatment (e.g., silanization).	Ensures stable polishing slurry with slow settling, facilitating automated production and guaranteeing process stability.

Typical Applications & Grit Selection
Application Areas	Typical Workpiece Materials	Recommended Grit Size (FEPA)	Value and Polishing Objectives
Precision Optical Components	Optical glass, crystal, microcrystalline glass, sapphire cover plates	F800 – F1500	Achieve nanoscale surface finish (Ra 0.2–0.5 µm) and high surface figure accuracy, minimize light scattering, ensure imaging quality.
Semiconductor Substrates	Silicon wafer, silicon carbide (SiC) ,arsenide (GaAs) substrate	F1000 – F2000	Used for backside thinning and CMP processes, achieve global planarization with no surface damage layer, improve device electrical performance and reliability.
High-end Metal Components	Stainless steel mirror rods, aluminum alloy hard disk substrates, precision mold steel	F600 – F1200	Obtain metallic mirror finish without orange peel or micro-scratches, improve surface corrosion resistance, wear resistance, and aesthetics.
Industrial Ceramics and Gemstones	Zirconia ceramic parts, silicon nitride bearing balls, synthetic gemstones	F400 – F1000	Efficiently remove fine grinding marks, achieve high-gloss effect with no edge chipping, maintain material integrity.
Luxury Goods Surface Treatment	Watch cases, jewelry, high-end pen accessories	F800 – F1500	Achieve deep, uniform mirror effect, enhance product grade and added value.
