Investigation of the Structure and Phase Composition of Aluminum Oxide Powders Obtained by Chemical Dispersion of an Aluminum Alloy with Different Magnesium Content

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.…”
