Structure of aluminum hydroxide powders obtained as a byproduct of hydrogen fuel production

Structure and Phase Composition of Ceramics Made of Powder Obtained by Chemical Dispersion of V95 Alloy

“…Chemical dispersion of alloy B 95 was carried out by treating it with a 20% aqueous solution of sodium hydroxide. The resulting powder was washed with distilled water and filtered by vacuum filtration [1][2][3][4][5].…”

“…Washing the precipitate was necessary to lower the pH and stabilize the solution, as well as to reduce the harmful bound Na + ions, it. This was realized using the technology of multiple washing of the powder by the decantation method [1][2][3][4][5].…”

“…The final pH value during washing the powder equal to 8.32 is reached at the 19-th stage of decantation [1][2][3][4][5].…”

“…Fine fraction sediment washed by decantation and dried (at 60 ° C) is then ground with a pestle in a mortar in order to obtain a free-flowing powder product [1][2][3][4][5].…”

“…From this viewpoint of great interest are powders obtained by the method of chemical dispersion of aluminum alloys in a caustic soda solution, which was developed at the Moscow State Industrial University (now the part of the Moscow Polytechnic University) [1][2][3][4][5]. This method makes it possible to obtain inexpensive feedstock with nanosized particles alloyed with various elements.…”
