Abstract
The perovskite structure is supported by several oxides that have the chemical formula ABO3. Barium Titanate (BaTiO3) is a member of the perovskite family. This structure takes its name from the CaTiO3. The general crystal structure is a primitive cube with the larger A cation in the corner, the smaller B cation in the middle of the cube, and the anion O in the center of the edges of the face, where A is a trivalent mineral, and B is a trivalent or pentavalent element. Barium Titanate (BaTiO3) fine Nanopowder was doped with silicon dioxide in various ratios to produce a homogenous fine Nanopowder. using the weight ratio. then sintering with different temperature (1000c◦C -1300◦C) in temperature raising rate (9◦C / 1min) , and investigation of the pure and doped mixture's physical properties. It was observed that the addition of SiO2 on BaTiO3 influence on physical properties, Physical tests depict with SiO2 addition that the volumetric shrinkage of the samples reduces with increasing temperature when SiO2 addition. For water absorption, we notice a decrease in water absorption with a reduced porosity due to the contraction of pores and reaching the glazing stage in some samples.
