Abstract The article deals with a laboratory preparation of triclinic modification clinker mineral tricalcium silicate. A substantial part the is devoted to technology and technique firing sample silicate, which would in future allow study development crystal lattice structure this at short isothermal durations, order minutes. As research, small high-temperature experimental furnace was designe...

This article presents a successful laser-powered co-firing process for highly efficient Si solar cells as more compact and energy-efficient alternative to the conventional firing in an infrared (IR) lamp-powered heat chamber. The best cell group reaches with laser only 0.1%abs lower efficiency compared firing, demonstrating industrial potential of this technology. Adding enhanced contact optimi...

The results of psychophysical studies suggest that displacement velocity may contribute significantly to the sensation of subcortical somatosensory neurons. The cortical correlates of these phenomena, however, are not known. In the present study the responses of rapidly adapting (RA) neurons in the forelimb region of cat primary somatosensory cortex (SI) to controlled displacement of skin and h...

In the current research project, sol-gel electrophoresis technique was utilized to grow titanium dioxide (TiO2) nanotubes. A titanium sol was prepared using organometallic precursors of titanium to fill the template channels. The prepared solwas driven into nanopores of porous anodic aluminum oxide templates under the influence of a DC electric field to form nanotubes on the pore walls. Tube fo...

Interfacial reaction between quartz and potassium silicate glass was studied at both 900 °C 1000 °C. The results showed that no phase transformation observed for the pure or Instead, particles in K2O-SiO2 glass, from to cristobalite occurred quartz/glass interface first, then crystals transformed into tridymite. tridymite formed became site of heterogeneous nucleation, which induces plenty prec...

The object of the research is firing temperature ceramic materials based on barium titanate. In laboratory conditions, titanate was synthesized from raw carbonate and titanium dioxide using technology, taking into account stoichiometric composition compound. order to study effect properties material, three temperatures were selected: 1270, 1300, 1350 °C. physical samples (imaginary density, wat...

Abstract This paper is devoted to research the interface failure mechanism of coating in gun barrel, three models (interface shear failure, bending and crack growth failure) barrel are built with consideration thermal-pressure coupling effect, criterion given. The critical length/thickness ratio segments for different during firing process calculated based on temperature field simulation result...
