Material for Emission Control Components
CER-VIT material, a glass-ceramic, has been used as a protective lining for containing the high-temperature gases in automotive thermal reactors. Lined reactors, utilizing the cyclonic mixing concept, have been road tested at operating temperatures of 1900-2000 F and have exhibited no deterioration of the liner. No thermal stress failures have occurred in liners subjected to rapid heatup from an ambient temperature of 0 F.
Methods of mounting the liners are being developed. The ceramic-to-metal gas seal designs are being explored, and progress in solving these and other problems will be reported.
