Über einige Messungen an Bariumtitanat
For circular piezoelectric discs formulae are given from which it is possible to calculate the mechanical constants of the disc material from electrical measurements. The dependence of temperature upon dielectric constant, the electrical loss factor, elastic modulus, mechanical loss angle and the piezo-modulus of BaTiO3 and the mixed ceramic BaTiO3-PbTiO3 have been measured, and are represented diagrammatically. The numerical value of the mechanical and electrical constants of barium titanate are collected in a table.
