Abstract.
Barium strontium titanate (BaxSr1-xTiO3) are ferroelectric materials that have high dielectric, low dielectric loss and spontaneous polarization. [6].
The influence of BST addition on the optical and dielectric properties of the prepared BST/Na2O-B2O3-SiO2 glasses were studied and thermal parameters of these materials were analyzed.
The 25Na2O-13B2O3-62SiO2 (in wt. %) glass was prepared by mixing the raw materials of Na2CO3, B2O3 and SiO2 and the mixture was melted at 1200 ºC for 2 h.

This waste material has potential as a cost-effective reprocessing for transforming to building materials.
Materials The oxide composition of all raw materials was determined by X-ray fluorescence (XRF), as indicated in Table 1.
The ordinary Portland cement (OPC) was used as a binder for all the constituent materials.
All the materials except OPC were dried at 200°C.

Options for synthesizing nanocrystalline dual phase materials are attractive in more than one way and in addition to the stabilization effect: with multicomponent and - more importantly - multiphase materials, the most important tool of modern materials design would also become accessible for adjusting the often advanced or new properties of nanocrystalline materials to yield even more enhanced performance or functionality.
Such a tendency is quite unusual since conventionally, materials coarsen more rapidly at increased temperatures.
