Porous Ceramics

Smart Ceramic Solutions for Your Toughest Applications

Refractron has been making resilient alumina and SiC porous ceramics for critical applications for over 35 years. Our applications, materials and manufacturing expertise allows us to design parts with pore sizes ranging from 0.1 to 1000+ microns that can improve process reliability, reduce costs and drive performance.

Alumina

Alumina (aluminum oxide) is used in a variety of applications up to 800°C to replace metal, plastic, polymer or fabric. Alumina demonstrates excellent resistance to organic solvents and alkaline solutions up to ~50ºC (122°F).

Silicon Carbide

Silicon Carbide (SiC) porous ceramics with a hybrid reaction bond can withstand higher temperatures than traditional glass-bonded porous ceramics. Silicon carbide offers chemical durability, thermal shock and creep resistance for applications up to 1200ºC (2192ºF).
