Component Specifications

Definition
A precision-engineered ceramic component with controlled porosity, designed for filtration, gas/liquid diffusion, or uniform fluid distribution in junction systems. It features interconnected pores that allow selective passage of substances while maintaining structural integrity under pressure and temperature variations.
Working Principle
Operates through capillary action and pressure differentials across its porous structure, allowing fluids or gases to pass while trapping particulates or facilitating controlled diffusion. The uniform pore distribution ensures consistent flow rates and filtration efficiency.
Materials
High-purity alumina (Al₂O₃) or silicon carbide (SiC) ceramic, with porosity ranging from 20% to 50%, pore sizes from 0.1 to 100 microns, and sintering temperatures of 1400-1800°C.
Technical Parameters
  • Diameter 50-300 mm
  • Porosity 30-45%
  • Pore Size 5-50 μm
  • Thickness 5-25 mm
  • Max Pressure 10 bar
  • Max Temperature 800°C
  • Chemical Resistance High (pH 1-14)
Standards
ISO 5019, DIN 40685, ASTM C373
