Monolithic nanocrystalline SiC ceramics
(Elsevier Sci Ltd, Oxford, 2016)
Additive-free beta-SiC nanopowders were densified by using high-pressure "anvil-type with hollows" apparatus at the pressure of 4 GPa in the range of 1500-1900 degrees C. The starting powder with average particle size of ...
Cavitation resistance of refractory concrete: Influence of sintering temperature
(Elsevier Sci Ltd, Oxford, 2013)
The purpose of this study was to investigate possible application of refractory concrete in conditions of cavitation effect where the metal materials are usually applied. Also, influence of different sintering temperatures ...
Implementation of image analysis on thermal shock and cavitation resistance testing of refractory concrete
(Elsevier Sci Ltd, Oxford, 2010)
This paper presents monitoring of changes during thermal shock and cavitation testing for low cement concrete that was synthesized and sintered at 1600 degrees C for 3h. Water quench test was applied as an experimental ...
Ultra-high breakdown field varistors prepared from individually synthesized nanoprecursors
(Elsevier Sci Ltd, Oxford, 2015)
Previously synthesized nanocrystalline ZnO doped with cobalt and manganese, Bi2O3 and Sb2O3 were the precursors for high voltage varistors preparation. Varistor ceramics were sintered at 750 degrees C, 770 degrees C or 900 ...
Structural, ferroelectric and magnetic properties of BiFeO3 synthesized by sonochemically assisted hydrothermal and hydro-evaporation chemical methods
(Elsevier Sci Ltd, Oxford, 2016)
BiFeO3 powders were synthesized by sonochemically assisted hydrothermal and hydro-evaporation methods. The X-ray diffraction confirmed the presence of secondary phases, Bi25FeO39 and Bi2Fe4O9, in as prepared BiFeO3 powders. ...
