At the industrial level, aluminum nitrate is typically synthesized by reacting bauxite, an aluminum ore, with nitric acid.
The process involves several steps:
Bauxite digestion:
Bauxite is digested in nitric acid to form aluminum nitrate.
Al(OH)₃ + 3 HNO₃ → Al(NO₃)₃ + 3 H₂O
Purification:
The solution may contain impurities that are removed through methods such as filtration or centrifugation.
Concentration:
The purified solution of aluminum nitrate is concentrated by evaporating water, often under reduced pressure to lower the boiling point and prevent decomposition.
Crystallization:
Upon cooling, aluminum nitrate crystallizes out of the solution, which is then collected and dried.
LABORATORY PREPARATION OF ALUMINUM NITRATE:
In a laboratory setting, aluminum nitrate can be prepared using more precise and controlled reactions.

Direct acidification:
Pure aluminum or aluminum oxide (Al₂O₃) is reacted directly with dilute nitric acid.
2 Al + 6 HNO₃ → 2 Al(NO₃)₃ + 3 H₂↑
Al₂O₃ + 6 HNO₃ → 2 Al(NO₃)₃ + 3 H₂O
Temperature control:
The reaction is kept at a lower temperature to minimize the production of nitrogen dioxide (NO₂), a toxic byproduct.
Concentration and crystallization:
Similar to the industrial process, the resultant solution can be concentrated and crystallized to obtain the final compound.

The crystallization is a hydrate of aluminum nitrate.
The amount of water of crystallization depends on the concentration of nitric acid used and the cooling temperature.
If the relative density of nitric acid is 1.42 and the cooling temperature is 20 °C, the precipitate is nonahydrate.

To prepare anhydrous aluminum nitrate, aluminum bromide and nitric acid chloride (ClNO₃) in liquid bromine is used.
The reaction is conducted below -7 °C.
Due to the explosive nature of nitric acid, caution must be taken.
Anhydrous aluminum nitrate is highly hygroscopic and is easily converted into nonahydrate.
PROPERTIES OF ALUMINUM NITRATE:
*Chemical
Aluminum nitrate reacts with sodium hydroxide, precipitating Aluminum hydroxide:
Al(NO₃)₃ + 3 NaOH → Al(OH)₃ + 3 NaNO₃
Thermal decomposition of aluminum nitrate produces Aluminum oxide, nitrogen dioxide and oxygen.
This reaction takes place between 150–200 °C.
2 Al(NO₃)₃ → Al₂O₃ + 6 NO₂ + 3/2 O₂
*Physical
Aluminum nitrate is an odorless, white crystalline hygroscopic salt.
Aluminum Nitrate has good solubility in water (73.9 g/100 ml at 20 °C), but is less soluble in alcohols and ethylene glycol.
Aluminum Nitrate melts at 66 °C (anhydrous) and 73.9 °C (nonahydrate), and if heated higher the nonahydrate will decompose.
PREPARATION OF ALUMINUM NITRATE:
Aluminum nitrate cannot be made by adding Aluminum to nitric acid, as the Aluminum forms a passivation layer which prevents the reaction from taking place.
One way around Aluminum Nitrate is to add nitric acid to another compound of Aluminum, such as Aluminum chloride, a reaction which gives off nitrosyl chloride fumes.
If you want to avoid the fumes, use Aluminum hydroxide as a precursor chemical, which can be obtained by adding a soluble hydroxide to an Aluminum salt.
This reaction however will yield the hydrated form.
Obtaining anhydrous Aluminum nitrate is difficult, as it tends to decompose when heated, making it a poor choice for oxidizer in pyrotechnic mixtures.
