TL;DR: In this article, the microwave characteristics of the binary-system TiO2-Bi2O3 ceramics, which exhibit a comparatively high dielectric constant in the lower frequency band, are investigated from a new standpoint.
Abstract: The microwave characteristics of the binary-system TiO2-Bi2O3 ceramics, which is widely known to exhibit a comparatively high dielectric constant in the lower-frequency band, are investigated from a new standpoint It is shown in this article that the composition of 0919TiO2-0081Bi2O3 has a high dielectric constant (er=80), high Q (1800 at 5 GHz) and low temperature coefficient of resonant frequency (τf=+21 ppm/°C) From the X-ray diffraction and X-ray microanalysis, it is indicated that the crystal structure of this material is composed of two phases, TiO2 and Bi2Ti4O11, which possess a high er with a negative temperature coefficient and a high er with a positive temperature coefficient, respectively The measurements of linear thermal expansion and temperature coefficient of capacitance are also carried out in order to study the behavior of temperature compensation in this system

TL;DR: In this paper, the loss of gravitational energy on core formation is calculated for the case of simple unmixing of two components, whose equations of state are found from the present density distribution.
Abstract: The loss of gravitational energy on core formation is calculated for the case of simple unmixing of two components, whose equations of state are found from the present density distribution. Without allowance for thermal expansion, the mean energy available for heating is 600 cal/g; with an approximate allowance for thermal expansion, this is reduced to 400 cal/g, which is equivalent to a mean rise of temperature of about 1600°. The moment of inertia of the undifferentiated earth is found to be about 10% greater than that of the present state, for the spherical model.

TL;DR: In this paper, a finite element model is developed to simulate three-way coupling of thermal, electrical and mechanical behavior of electric current-activated sintering, which is capable of simultaneously calculating the displacement fields and the stress distributions.
