Product DescriptionProduct DescriptionUltra-Fine Green Silicon Carbide Micro PowderHenan Yumo New Materials' ultra-fine green silicon carbide micropowder is a functional powder made from ultra-high-purity silicon carbide (SiC) synthesized using a unique process, then ultra-finely pulverized and precisely graded. Its particle size distribution typically ranges from F230 (53 μm) to F2000 (3 μm), even down to the submicron level. Its exceptional hardness, excellent thermal conductivity, and chemical stability make it a preferred material for high-end precision grinding, polishing, and advanced ceramics.SpecificationKey Characteristics & AdvantagesCharacteristic DimensionDetailed DescriptionValue Created for CustomersExtreme Hardness & Wear ResistanceMohs hardness up to 9.2–9.3, second only to diamond and cubic boron nitride (CBN); excellent wear resistance.Powerful cutting performance and long service life: far superior efficiency in machining hard and brittle materials, with low unit consumption.Excellent Thermal Conductivity & StabilityHigh thermal conductivity effectively dissipates grinding heat; retains strength even at 1600Reduces workpiece “burning”: prevents localized overheating and surface degradation, ideal for heat-sensitive materials.High Purity & Chemical InertnessSiC content ≥ 99%, with extremely low levels of free carbon and metallic impurities.Clean, contamination-free surface: chemically stable, non-reactive with workpiece, ensuring final performance integrity.Precise Particle Size ControlAdvanced classification technology ensures narrow particle size distribution (Span < 0.8), with no oversized particles.Delivers uniform surface quality: enables predictable material removal rate and nanometer-level surface finish, free from unexpected scratches.Sharp Particle MorphologyParticles feature sharp edges and strong cutting ability.High grinding efficiency: maintains strong material removal capability in both rough and fine grinding stages.Typical ApplicationsApplication AreaRecommended Grit SizeValue DeliveredSemiconductor MaterialsF1000 – F2000Back-side thinning and CMP of Si, GaAs and SiC wafers; damage-free, metal-contamination-free surfaces.Precision OpticsF800 – F1500Fine grinding & polishing of optical glass, quartz, sapphire and glass-ceramics; achieves nanometric surface finish (Ra < 0.5 nm) and high form accuracy.Advanced CeramicsF400 – F1200Precision grinding of structural/functional ceramics (ZrO2, Al2O3, Si3N4); high MRR and chip-free edges.Surface Treatment & CoatingsF600 – F1000Wear-resistant filler for paints, plastics and rubbers; markedly improves abrasion and scratch resistance.Quartz & Crystal DevicesF500 – F1500Precision machining of quartz-crystal resonators and optical quartz glass; excellent surface quality with no degradation of piezo-optical properties.Product SpecificationsParameter CategoryHenan YUMO SpecificationTest MethodChemical CompositionSiC: ≥ 99 %Chemical analysis / XRFFree C: ≤ 0.20 %Fe2O3: ≤ 0.08 %Mohs Hardness9.2 – 9.3Mohs hardness testerParticle-Size RangeF230, F240, F280, F320, F360, F400, F500, F600, F800, F1000, F1200, F1500, F2000Laser particle-size analyzer(or JIS #800 – #8000)Magnetic Content≤ 40 ppmMagnetic-separation measurementSurface TreatmentOptional (hydrophilic, hydrophobic, silane, etc.)—Why Choose Henan YUMO?Dual Control of Purity and Particle Size: We not only strive for high chemical purity (SiC ≥ 99%), but also utilize multi-stage precision grading technology to ensure a highly concentrated particle size distribution, which is key to achieving a flawless machined surface.Customized Solutions: We can provide the most suitable particle size recommendation based on your specific application (e.g., polishing workpieces of different materials) and can also perform special surface treatments (such as silanization) to improve dispersion.Stable and Traceable Quality: Each batch of product is provided with a detailed Certificate of Authenticity (CoA) containing key data such as laser particle size distribution and chemical composition, ensuring consistent product performance.Strong Technical Support: Our team of application engineers offers free technical consultation and sample testing services to help you optimize your existing processes and resolve machining challenges.Recommended Related Products DisplayCompany ProfileHenan Yumo New Materials Co., Ltd. is a leading manufacturer of high-quality abrasive and refractory materials, specializing in white fused alumina, brown fused alumina, and silicon carbide.
