A dielectric ceramic article precursor and a process for preparing a dielectric ceramic article are presented. The ceramic article precursor comprises a crystalline aluminosilicate zeolite or an amorphous aluminosilicate and a glass phase. The ceramic article precursor can optionally contain at least one forming aid selected from binders, plasticizers and surfactants. Metal oxide additives such as B2O3or SnO2as well as metal oxide precursor additives such as nitrates or carbonates of metals such as boron or tin can also be included in the ceramic article precursor. The process for preparing a dielectric ceramic article involves forming a mixture from the above components into a shaped article such as a tape and then calcining the shaped article at a temperature of about 700° C. to about 1000° C. for a time of about 0.5 to about 24 hours.
