Ceramic packing can survive high stable temperatures yet fail during rapid heating or cooling. Thermal gradients create internal stress, and brittle ceramic cannot easily relieve that stress. Startup, shutdown and quench procedures should therefore control temperature-change rates.

Why Acid-Resistant Ceramic Can Still Fail in Strong Alkali Service
Conventional acid-resistant ceramic may have excellent performance in many acids but significantly lower resistance to strong caustic solutions. For NaOH, KOH and other alkaline service, evaluate alkali resistance, concentration and temperature separately before selecting ceramic packing.

Ceramic Packing Acid Resistance Test: How to Interpret a 99%+ Result
A 99%+ ceramic acid-resistance value indicates low material loss under specified test conditions. It does not prove compatibility with every acid or every operating temperature. Use it as one material-quality parameter, not as a complete process-compatibility guarantee.

Water Absorption of Ceramic Packing: What Does the Test Really Tell You?
Water absorption tells engineers about the accessible pore structure of ceramic packing. Lower values can indicate better vitrification, but “lower is always better” is an oversimplification. Evaluate the number against the ceramic grade, product geometry, test method and required service conditions.
