Density: 4.64 g/cm3
Melting Point: 1250 degrees
Curie Point: 1142+/- degrees
Mohs Hardness: 55
Dielectric Constant: E11/e0 = 85; E33/e0 = 29.5
Thermal Conductivity: 38 W/m egrees at 25 egrees
Thermal Expansion Coefficient: A1=a2 =2x10-6 egrees, a3=2.2x10-6/ degrees at 25degrees
Piezoelectric Strain Constant: D22 = 2.04 x 10-11 C/N, d33 = 19.22 x 10-11 C/N
Elastic Stiffness Constant: CE11 = 2.04 x 1011 N/m2, CE33 = 2.46 x 1011 N/m2
