Product DescriptionProduct DescriptionHigh Purity Green Silicon Carbide—Ultimate Purity, Superior Performance, Empowering High-End Industry and Cutting-Edge Technology—Henan Yuno New Materials produces high-purity green silicon carbide, a specialty silicon carbide material made from high-quality petroleum coke and silica stone. After smelting in a high-temperature resistance furnace, it undergoes a series of unique purification, crushing, grading, and purification processes. Its core characteristics are extremely high chemical purity (SiC ≥ 99.9%) and extreme control of specific critical impurities, making it an ideal choice for manufacturing high-performance engineering ceramics, semiconductor processing consumables, high-end refractory materials, and functional fillers.SpecificationKey Characteristics & AdvantagesFeature DimensionDetailed DescriptionValue Created for CustomersExtremely High Chemical PuritySiC content ≥ 99.9%, significantly higher than typical green silicon carbide (~99%). Impurities such as metal oxides are reduced via acid washing and high-temperature purification.Superior chemical and thermal stability: maintains stable performance under high temperatures or harsh chemical environments, avoiding unexpected reactions caused by impurities.Ultra-Low Critical ImpuritiesFe2O3 ≤ 0.05%, free carbon ≤ 0.10% (can be further reduced upon request).Contamination-free: prevents contamination from iron or other impurities during processing, ensuring the purity and performance of the final product.High Hardness and Wear ResistanceMohs hardness of 9.2–9.3, recognized as a highly efficient grinding and wear-resistant material.Extended service life and high cutting efficiency: as an abrasive or wear-resistant component, it far outperforms conventional materials in durability and efficiency.Excellent Thermal Conductivity and Thermal Shock ResistanceHigh thermal conductivity, low thermal expansion coefficient, and resistance to rapid temperature changes.Stable performance at high temperatures: ideal for high-temperature kiln furniture, heat exchanger components, and other applications subject to thermal cycling.Precise Particle Size ControlFull range from coarse particles to micro-powders with tightly controlled and concentrated particle size distribution.Consistent processing results: ensures predictable and uniform outcomes in grinding, polishing, or as a filler material.Typical ApplicationsApplication AreaRecommended Grit SizeValue DeliveredHigh-performance Engineering CeramicsF240 – F800 (fine powder)Acts as a sintering aid or reinforcing phase in the production of advanced ceramics such as reaction-bonded SiC (RBSC) and pressureless-sintered SiC (PLSIC). The ultra-high purity is essential to achieve outstanding mechanical (high strength, high toughness) and thermal properties.Semiconductor Material ProcessingF500 – F2000 (micro-powder)Used for slicing, lapping and polishing semiconductor wafers, sapphire substrates and quartz glass. The high purity and hardness guarantee high processing efficiency and a contamination-free surface finish.Premium RefractoriesF24 – F90 (aggregate) F100 – F320 (fine powder)Used to produce blast-furnace trough mixes, kiln furniture (saggers, push plates), and linings for aluminum electrolysis cells. The high purity provides excellent corrosion resistance, oxidation resistance and high-temperature strength, markedly extending the service life of furnaces and components.Specialty Coatings & Functional FillersF600 – F1200Incorporated into polymers or coatings as a wear-resistant or thermally-conductive filler, greatly enhancing scratch resistance, abrasion resistance and thermal-management capability for high-end flooring, heat-dissipation coatings, etc.Photovoltaic Silicon Wafer Wire-sawingF800 – F1500 (micro-powder)Formerly widely used for loose-abrasive slurry cutting of crystalline-silicon PV wafers; although largely replaced by diamond wire, it is still employed in certain niche areas.Product SpecificationsParameter CategoryYUMO High-Purity Grade SpecificationTest MethodChemical CompositionSiC: ≥ 99.9 %Fe2O3: ≤ 0.05 %Free C: ≤ 0.10 %SiO2: ≤ 0.15 %Chemical analysis / XRF spectrometryMohs Hardness9.2 – 9.3Mohs hardness scaleBulk Density1.90 – 2.10 g cm-3 (grain-size dependent)GB/T 3600-2018Magnetic Content≤ 50 ppmMagnetic separation measurementParticle-Size RangeFull range availableMacro grains: F16, F20, F24, F30, F36, F40, F46, F54, F60Fine powders: F70, F80, F90, F100, F120, F150, F180, F220, F240…Micro-powders: F280, F320, F400, F500, F600, F800, F1000, F1200…Laser particle-size analyzer / sieve analysisWhy Choose Henan YUMO?Clear Purity Advantage: We specialize in producing high-purity SiC products with a purity of ≥99.9%, and we selectively control key impurities like Fe and C to meet your demanding material performance requirements.Outstanding Customization Capabilities: We can adjust the chemical composition and particle size combination to provide the most suitable solution for your specific application (such as sintering specific ceramics or formulating specific coatings).Stable and Reliable Quality: From raw material screening to finished product packaging, we implement a strict quality control process to ensure highly consistent chemical composition and physical properties of each batch, guaranteeing the stability of your production.Technical Support: Our technical team provides free consultation on material selection, application process optimization, and other aspects, helping you solve technical problems in actual production.Henan Yumo New Materials — Your trusted supplier of high-performance silicon carbide materials.We are committed to enhancing the core competitiveness of your products through innovative material solutions.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.
