This chapter aims to describe about the Application of Dielectric Mixtures Formulae for PbTiO3 based Glass-Ceramic systems. Using a traditional quenching procedure, glass samples with the composition (50 - X) PbO - (25 + X) TiO2 - 25 B2O3 (where X =0, 5, 10 and 12.5 mol %) were created. These glass samples underwent two stages of heat treatment in order to become glass ceramics. Glass and glass ceramic samples were evaluated for density, transition temperature (Tg), crystallization temperature (Tc), and coefficient of thermal expansion (CTE). Tg and Tc were shown to decrease as TiO2 content increased. Glass ceramic samples have densities that are higher than corresponding glass samples. It was noted that the density and CTE results of the glass-ceramics showed a strong association. Glass ceramic samples have a greater dielectric constant than equivalent glasses. The theoretically anticipated and experimentally observed values of the dielectric constant were correlated using Maxwell's dielectric mixture formula.
