Material Characteristics

The use of different particle size particle gradation of silicon carbide micro-powder (particle size is usually in the 50-100μm) as raw materials, 3D printing molding process (usually can be binder jetting process, light curing, fused deposition and laser sintering), high-temperature reaction sintering under the protection of vacuum or argon, the liquid-phase infiltration of silicon is usually in the 1400-1600 ℃, the gas-phase infiltration of silicon temperature is usually in the 1600-1800 ℃), the density is usually 2.80-3.10g/cm3, free silicon content is usually 10-30%.

 

Performance Characteristics

  • Excellent abrasion resistance (typically Vickers hardness over 20 GPa)
  • High temperature resistance (typical service temperature > 1300°C)
  • High thermal conductivity (room temperature thermal conductivity typically greater than 100 W/m¡K) and low coefficient of thermal expansion (room temperature CTE typically less than 4*10-6/K)
  • Full chemical resistance
  • Purity up to 99.98%
  • Can manufacture large size and complex structural components
  • Sanzer New Material independently researches and develops 3D printing reactive sintered silicon carbide materials according to the product application characteristics of reactive sintering, especially for high purity
