- 15 - ABSTRACT OF THE DISCLOSURE A process for fabricating cordierite-type mag- nesium aluminum silicate regenerator cores comprising the steps of preparing a glass powder and combining it with a block polymer binder, forming the binder and glass- ceramic mixture into a ribbed tape which is wound upon itself to produce a honeycomb structure and subjecting the honeycomb structure to firing cycles to achieve binder burn-off, controlled nucleation, densification and crystal- lization whereby the glass-ceramic structure is character- ized by a relatively low thermal expansion during opera- tion in an environment where temperature reversals occur. the glass ceramic structure thereby being more resistant to chemical attack due to corrosive gases in an engine exhaust gas environment and the strength of the structure thereby being increased.
