Porous ceramic disc Component – Non-Metallic Mineral Product Manufacturing

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
