For aircraft manufacturer’s this means higher efficiency to produce aircraft which is possible only with new design techniques, new technologies and new materials but never compromising the safety of the structures [29].
This forming process require large machine and tooling or some materials such as AlMgSc alloys can be stretch-formed only in soft temper condition and an additional final temper is required increasing the cost.

To make components compact and high-capacity, it is necessary to make the dielectric layer thinner, increase the dielectric constant of the dielectric materials, increase the number of layers, and increase the area of internal electrodes.
The other studies have been done on the material development of elements of thin dielectric substance, production process improvement, and increasing the dielectric constant of dielectric materials [3~5].
Ceramic materials, various additives, and polymer binders are mixed, followed by casting into dielectric sheets of some microns in thickness, and then printing internal electrodes on the sheets.

This paper proposes a new technique, called gelatinization, for processing this class of ceramics in order to obtain materials with more controlled pore size, plus a more homogeneous distribution.
The technique used in the processing of ceramic materials directly affects their characteristics such as chemical composition, particle morphology and porosity of the sample.
The third method is the gelcasting (direct foaming), which is widely used due to its low cost and the facility of manufacturing of ceramic materials with high porosity percentage, reaching an amount of 95% of pores.
