Address: Lingshou County Nanyan Chuan township Dongzhuang village Types of Silicon Carbide Industrial classification primarily recognizes two distinct types of this exceptional material: Green Silicon Carbide Green silicon carbide presents the purest form with approximately 99.5% SiC content. Its exceptional hardness (9.5 Mohs) makes it invaluable for precision grinding of cemented carbides and low-tensile strength materials. The manufacturing process requires petroleum coke, premium silica sand, and wood chips processed at 2,200-2,400°C in electric resistance furnaces. The green silicon carbide variant exhibits exceptional crystal structures with sharper fracture planes that enhance cutting efficiency while minimizing thermal damage to workpieces. Sintered Silicon Carbide Sintered silicon carbide represents the advanced synthetic form manufactured through sophisticated ceramic processing techniques. Densification via pressureless sintering yields materials with near-theoretical density (98-99%) and uniform microstructure. The resulting product exhibits exceptional mechanical properties including flexural strength exceeding 450 MPa and fracture toughness reaching 4.5 MPa·m 1/2 . Sintered silicon carbide components are increasingly deployed in extreme environments including semiconductor processing, molten metal handling, and aerospace applications.

Advanced Ceramics Components manufactured from sintered silicon carbide endure extreme operating conditions including: High-temperature gas environments exceeding 1,400°C Thermal cycling conditions with ΔT >800°C Severe abrasive/erosive environments High-corrosion chemical processing Production Gallery Technical Questions & Answers What are the key differences between green and black silicon carbide? Green silicon carbide (∼99.5% SiC) features higher purity and slightly greater hardness (9.6 vs 9.4 Mohs) due to lower impurity content. It contains less than 0.05% free silicon/carbon versus 0.5-1.2% in black SiC. Crystal structure variations yield different fracture characteristics: green SiC forms sharper fracture planes while black SiC exhibits more conchoidal fracturing. Green SiC provides superior performance on cemented carbides and low-tensile materials, whereas black SiC is preferred for glass, stone, and non-metallic surfaces. What standards govern silicon carbide particle size distribution? Grit sizes are standardized under: FEPA F Standard : European Federation of Abrasive Producers (EN 13799) JIS R6001 : Japanese Industrial Standard ANSI B74.12 : American National Standard Institute These standards classify abrasives according to nominal grit sizes (F4-F1200) and define particle distribution limits. Precision sizing is critical for consistent surface finish quality. What is the maximum service temperature for sintered silicon carbide? Under inert atmospheres, sintered silicon carbide maintains structural integrity to 1,650°C. In oxidizing environments, the practical service limit is 1,550°C due to passive oxidation effects. Continuous exposure above this temperature initiates active oxidation where SiC reacts with oxygen to form gaseous SiO. Protective CVD coatings like silicon carbide can extend upper temperature limits by 50-100°C in aggressive environments. How does silicon carbide compare to other structural ceramics? Compared to alumina, silicon carbide demonstrates 2× higher thermal conductivity, 50% greater flexural strength, and superior thermal shock resistance despite similar density levels. Against zirconia, SiC shows 3× better chemical resistance in acidic environments and maintains mechanical properties at higher temperatures. The thermal conductivity advantage over aluminum nitride makes SiC preferable for high-power thermal management applications. What safety precautions are required when handling silicon carbide abrasives? Mandatory safety measures include: NIOSH-approved respiratory protection for particulate matter ANSI Z87.1-compliant eye protection with side shields Industrial ventilation maintaining 25-100 fpm capture velocity Regular atmospheric monitoring for respirable crystalline silica (though SiC itself contains 400 MPa after pressure-assisted sintering cycles. This eliminates traditional machining constraints for complex geometries. The semiconductor industry's shift toward 200mm silicon carbide wafers promises significant cost reductions in power electronics manufacturing. Industry forecasts project 200mm SiC substrates will capture 35% market share by 2028, reducing device costs by 15-20% through manufacturing efficiencies.
