Barium strontium titanate (BaxSr1-x)TiO3 films are expected to be utilized for microwave integrated circuit devices; therefore, the preparation of highly crystalline BST films has been investigated. In this study, we attempted to prepare (BaxSr1-x)TiO3 films on MgO and sapphire substrates by sputtering under various conditions. It was revealed that BST films could be obtained at lower substrate temperatures...
Recently, information and communication technologies have been developing rapidly. Dielectric materials for microwave and milliwave devices have been widely investigated. In particular, (Ba, Sr)TiO3 (BST) is expected to be utilized for these devices since BST has high permittivity at high frequencies and nonlinear properties. We have developed a preparation method for BST films and have applied the...
As a candidate of a lead-free positive temperature coefficient of resistivitiy (PTC) themistor material, barium titanate (BaTiO3) -based solid-solution ceramics, BaTiO3-(Bi1/2K1/2)TiO3 (BBKT100x), have been synthesized by the conventional ceramic fabrication technique. The maximum temperature of the dielectric constant (Tm) of the BBKTIOOx ceramics monotonously increased with the increasing amount...
In order to prepare lead-free BaTiO3 - based positive temperature coefficient of resistance (abbreviated to PTCR) ceramics, 2.0, 4.0, 6.0, 8.0, 10 mol % of Bi1/2Na1/2TiO3 (abbreviated to BNT) added Ba 0.92Sr0.08TiO3 (abbreviated to BST) were fabricated by the conventional solid state reaction. Phase and microstructure characterizations revealed that no obvious BNT phase was found in the final sintered...
