ESL 42520 is a porous fired alumina ceramic plate used to cover green ceramic partsduring firing. The weight of the porous plate enhances the flatness of fired parts whileretaining gas permeability during organic removal, thus allowing single firing. The plate may also be used as a setter to promote more uniform burnout of binders during firing. Uses include Fuel Cell applications such as SOFC electrolyte substrates, and other processing of ceramic tape. ESL cover plates are available in several standard sizes as shown below, and incustomer-specific configurations.
