Piezoelectric Properties of Modified PbTiO3 Ceramics
PbTiO 3 ceramics with high density and high resistivity have been prepared by adding less than 5 mol % of Bi 2/3 TiO 3 , PbZn 1/3 Nb 2/3 O 3 or their derivatives. These ceramics have dielectric constants of about 200, and can be poled at 200°C under a d. c. field of 40 to 70 kV/cm. The piezoelectric coupling factors k…
Oxide Glasses in Light of the “Ideal Glass” Concept: I, Ideal and Nonideal Transitions, and Departures from Ideality*
This two‐part paper develops a basis for discussing glass properties which has features in common with standard “actual vs. ideal” treatments of physicochemical behavior, by defining thermodynamically an ideal state for the glass and discussing the states of the actual glasses in terms of their “departures from ideali…

Dynamical Theory of the Phase Transition in KH2PO4-Type Ferroelectric Crystals
Dynamical aspects of the ferroelectric phase transition in KH 2 PO 4 -type crystals are elucidated on the basis of the coupling between the proton tunneling mode and the optical mode vibration of the [K-PO 4 ] complexes along the c-axis. Two coupled modes are obtained within the framework of a linear theory. The mode…

Diffusion during the coagulation step of wet‐spinning
Abstract The coagulation of viscous polymer solutions by diffusional interchange with a liquid bath is the key step to fiber formation by wet‐spinning. Model experiments were performed on gelled solutions of an acrylic polymer in dimethylacetamide, to determine the mass‐transfer rates of solvent and nonsolvent (water)…

Formation and structure of the potassium graphites
The progressive intercalation of graphite by potassium has been studied by x-ray diffraction methods. It has been established that potassium graphites of stages 4, 3, 2 and 1 (with intercalated potassium layers separated by 4, 3, 2 and 1 graphite layers respectively) can be formed successively within a single graphite…

X-ray investigations concerning the physical structure of cross-linking in segmented urethane elastomers
In the X-ray diagrams of some segmented urethane elastomers, so-called hard-segment interferences can be observed which indicate a defined geometrical accumulation of the hard segments. These interferences can easily be traced back to a system of hydrogen bridges between the hard segments. They allow an insight into t…
