Introduction (Ba,Sr)TiO3, one of the most popular ferroelectric materials, has received much attention as dielectric materials for electronically tunable microwave devices, such as phase shifters, filters and delay lines, due to their electric field dependent permittivity [1-4].
Experimental The films of Ba0.6Sr0.4TiO3 precursor solution were synthesized using barium acetate, strontium acetate semihydtate and titanium tetra-n-butoxide as source materials.
The PbO precursor solutions with different concentrations were prepared using lead acetate as source materials.
Now we explore the possible applications of these materials in tunable microwave applications.

Introduction Thermal resistance of buildings materials belong among one of the important characteristics, especially for those materials, which are used in constructions with higher fire hazard.
Although concrete is one of the most utilized materials in civil engineering, just little attention was focused on research of this material in high temperature conditions.
During the temperature loadings a steeper increase of deformation shows materials with the silica sand.
