Fine zinc oxide particles were electrophoretically deposited on alumino-ferro-chrome substrates. The deposition was carried out in a cylindrical ZnO/acetone electrophoresis cell. The deposits were dried and sintered at 1030³C in air. The process resulted a porous polycrystalline ZnO cladding over the alloy core. Comb shaped silver electrodes were formed and fired at 350³C. The variation of dev...
The kinetics of molybdenite oxidation was studied by non-isothermal TGA-DTA with heating rate 5 ºC.min-1.The model-fitting kinetic approach applied to TGA data .The Coats-Redfern method used for model fitting. The popular model-fitting gives excellent fit for non-isothermal data in chemically controlled regime. The apparent activation energy was determined to be about 34.2 kcalmo...
The analysis of the process thermal modification wood, which was modified by a controlled pyrolysis wood heating (> 180 ° C) in absence oxygen, causes some chemical changes structures cell wall components (lignin, cellulose and hemicellulose), durability. It is proved that decomposition hemicelluloses amorphous part occurs, therefore amount substances are environment for development fungi si...
