Dense, polycrystalline barium titanate (BaTiO3) specimens showed a modulus of rupture of 85.5 +/- 9.0 MPa and a compressive strength of 486 +/- 75 MPa. These values are considerable higher than those which had been previously reported. In addition, t

A piezoelectric ceramic has been investigated as a direct substitute for hard tissues. Barium titanate (BaTiOz) power was slipcast and fired at 1430 degrees C for 2 hr, then made piezoelectric by polarizing. After 16 and 86 days of implantation in th

The fiber method developed by Schwalbe, Badger, and Silverman for comparing the tensile strengths of glasses was used to compare the tensile strengths of sheet-iron ground-coat enamel glasses whose feldspar, borax, and quartz contents varied within w

The potentials and limitations of high dielectric constant capacitors are briefly outlined. Additives used to modify the dielectric properties of BaTiO3 are listed and classified into two groups: 1. the ?shifters,? whose additions primarily cause a s
