16 Ιουν 2021 · In the sodium aluminate solution at Al (III) concentration up to 2.0 to 2.2 mol/L, the [Al (OH) 4] – monomer is dominant. In the region of the Al (III) concentration of 2.0 to 4.5 mol/L, in solution, monomers of aluminate ions prevail and their dimer forms [Al 2 O (OH) 6] 2– start to be formed.

1 Δεκ 2012 · Many metal oxides effectively modify metallic aluminum (Al) powders to produce hydrogen in neutral water at room temperature. In this study, hydrogen is generated even more rapidly from the...
1 Ιουν 2005 · Bayerite (α-Al(OH) 3) crystallization predominates from dilute sodium aluminate solutions, whilst for concentrated solutions the precipitated phase is predominately gibbsite (γ-Al(OH) 3). Solutions with an intermediate NaOH concentration gave rise to a dimorphic phase mixture.
31 Μαΐ 2009 · Research papers dealing with the identity and abundance as well as the structure of aluminium-bearing species present in pure and homogeneous, strongly alkaline aluminate solutions (often called synthetic Bayer liquors) published in the open literature since the 1970's have been reviewed.
In the present study, we systematically examined the influence of key anions, nitrite (NO2-) and nitrate (NO3-), as sodium salts on the solubility of α-Al(OH)3 in NaOH solutions taking care...
1 Δεκ 2012 · Many metal oxides effectively modify metallic aluminum (Al) powders to produce hydrogen in neutral water at room temperature. In this study, hydrogen is generated even more rapidly from the reacted solution when the by-product Al (OH) 3 (bayerite) is present.
1 Ιουν 1990 · At 25°C and pH 5, the calculated distribution of dissolved, inorganic aluminium hydroxides corresponds to about 36% of Al3+, 37 % of Al (OH)2+, 26 % of Al (OH)2+ and 1 % of Al (OH)30. At the same...
