It is suggested therefore that this new composite has good potential as a new candidate for low temperature co-fired ceramic (LTCC) materials.
Therefore LTCC compatible materials with adjustable permittivities � r>20 are also needed [5].
When fabricating desirable LTCC materials within the middle permittivity range being used as a module type, (often the low softening temperature glass frits and single oxides), usually B2O3 is mixed with the ceramic materials to reduce the high firing temperature of the ceramic materials.
The raw materials for the glass frit were La2O3, H3BO3 and TiO2 which all have high purity (Aldrich, USA).

This paper addresses a physics based derivation of mode-I and mode-II traction separation relations in the context of cohesive zone modeling of ductile fracture of metallic materials.
Introduction Ductile fracture of metallic materials involves generation of considerable porosity, where micro voids nucleate, grow and coalesce.
This approach was first introduced by [6] and subsequently used by [7] for modeling crack propagation in ductile materials.
