Abstract Intercalation complexes of a Hungarian kaolinite were prepared with hydrazine and potassium acetate. The thermal behavior and decomposition of the kaolinite-potassium acetate complex was studied by simultaneous TA-EGA, XRD, and FTIR methods. The intercalation complex is stable up to 300°C, and decomposition t…

Decarbonization of resin‐bonded magnesia‐graphite refractories, as one of the most important parameters for brick lining performance in service, has been studied kinetically in the temperature range from 1000° to 1400°C in air, where carbon burnout by oxygen is the dominant decarbonizing mechanism. The rate of carbon…

Raman experiments have been carried out on single crystals of ${\mathrm{BaTiO}}_{3}$ as a function of pressure up to 3.5 GPa across the ferroelectric (tetragonal) to paraelectric (cubic) phase transition. The unusual features in the Raman spectra associated with the interference effects due to coupling of the three ${…

The trapping of charges in hard dielectric materials has been recently described [G. Blaise, IEEE Trans. Electr. Insul. EI-28, 437 (1993)] on the basis of the polaron concept. A local increase of the internal energy of the medium Up∼5–10 eV results from the polarization around a trapped charge. The relaxation of the l…

Localization due to space structure, rather than due to randomness, is investigated by studying the usual tight-binding model on the Sierpinski gasket. Some exact results are obtained from the decimation--renormalization-group method. It is surprising that there exist an infinite number of extended states on the Sierp…

Various types of molecular bearings have recently been proposed in the growing nanotechnology literature. Using novel molecular dynamics methods, we have simulated several model graphite bearings. The bearings varied in size from inner shafts of between 4 and 16 A in diameter, up to 120 A in length, and outer cylinder…

SiC fibers were synthesized from polycarbosilane (PCS) fibers by heat treatment after electron beam irradiation curing. The pyrolysis reaction mechanisms from the organic PCS to ceramic SiC were investigated by the analysis of gases evolved during heat treatment. There were two steps in the major reaction: the first s…
