Sodium aluminates

As the only European manufacturer of solid sodium aluminate, we enable you to choose between solid and liquid form. The possible applications range from water treatment and chemistry to the construction industry. You can choose between different purities, grain sizes, as well as stabilized and non-stabilized forms.

Products

ALUCOM AG produces sodium aluminate solutions with various aluminum and sodium contents and molar ratios, as well as in various purity grades. We also produce solid sodium aluminate.

Examples of our products include:

Sodium aluminate solid (53-55% Al₂O₃)
Sodium aluminate solution 19% Al₂O₃
Sodium aluminate solution 24% Al₂O₃
LUPREAL® 7
LUPREAL® P

Grain sizes and stabilization

Our solid sodium aluminate is available in various grain sizes, from granulated to ground to finely ground. This allows you to choose the exact fineness that suits your process.

We offer our solid sodium aluminate in stabilized or unstabilized form. If you have special requirements for grain size or stabilizer, we will be happy to advise you and work together to find the right solution.

Scopes

In contrast to other aluminum compounds, the aluminum in sodium aluminate is present as a complex anion. Positively charged substances can thus be discharged and precipitated. Sodium aluminate is therefore used, among other things, in water treatment and in the production of paper.

In addition, it is suitable for a wide variety of industrial production processes and applications as an alkaline aluminum source.

Last but not least, sodium aluminate can also be used as a setting accelerator for cement-bound systems. Please do not hesitate to seek our advice on this.

The areas of application for sodium aluminates are as follows:

Setting accelerator for cement-bound systems
Paper production
Flocculation, phosphate elimination in sewage treatment plants
Sulfate precipitation by inclusion in the floc or ettringite process
Alkaline aluminum source for chemical synthesis
