POROSITY (% VOLUME)
Resistant to chemicals that do not attack phenolic resin. Not for alkaline solution Temp above 100F
Resistant to chemicals that do not attack silica glass. Not for strong alkaline solutions. Initial hydrolysis occurs.
Most resistant to chemical attack. Not recommended for hydrofluoric or phosphoric acids or strong alkaline solutions.

Notes:

More Refractory & Chemically Resistant Compositions are Available.

Special Grades & Other Materials, such as Silicon Carbide are also Available.

Particle Retention is a Gas is Approximately Ten Times Smaller.

This Data is Typical and is not Intended for use as Specification Requirements.
