Our Toolbox with manifold combinations – Your Choice for the Best Option
The Lohtragon® toolbox of currently more than 40 cations and anions is the basis for our metal salt response to your inquiry. Our proven Lohtragon® product range is just the starting point of nearly endless options for combinations, and therefore not exhaustive yet, and will be extended based on your specific needs and requirements.
With this modular chemical system our scientists ensure the transition from design level in our laboratories via sophisticated scale-up processes to the Lohtragon® manufacturing process. The relevant raw materials are carefully selected considering quality, appropriateness for the solely water-based manufacturing processes, sustainability aspects and long-term availability. Ultimately your value of all these possible combinations is your Lohtragon® product - up to your individual customer specification - matching precisely and consistently your requirements in all aspects.

Chemical Lohtragon® Competences
The variation of chemical compositions offers extensive opportunities. In this way, tailor-made metal salts can be synthesized meeting specific needs. Various case studies demonstrate these Lohtragon® competences.
Your Value:
- Wide capabilities in modifying chemical parameters
- High purity
- Optimized active content
- Variation of pH-value
- Improved solubility behavior
- Reduced hygroscopy and water content
Active content
Are you looking for a high content of your active component to improve the efficiency of your process?
Many processes and chemical reactions require highest possible share of an active component as it leads to a maximized efficiency and yield increase.
With our chemical expertise we customize metal salts around your active cation and anion, for example in catalytical systems.
The graph of our different Lohtragon® Iron Sulfates gives you an insight about what is possible.
Within one product group from our standard portfolio we cover different iron contents ranging from approx. 7.5 % up to approx. 32 %.
Customized developments according to your requirements are possible, too.
- Is a high Iron content important for you e.g. in the formulation of Iron promoted activated alumina?
- Do you need a maximum of Magnesium in your process for coating catalyst carriers?
- Or do you have any further special active component requirement?

pH variation
The optimization of the pH-value is relevant for production processes and final products in many applications, such as:
- Surface Treatment – Electroplating and metal surface etching
- Polymer Additives
- Energy – Electrolytes for batteries
- Sensitive aqueous formulations (e.g. adhesives, paints, textiles) and more
By varying the pH-value of a metal salt important properties of such solid materials can be optimized:
- Solubility behavior
- Decomposition temperature 
- Crystal structure and more
The showcase of Sodium Citrate demonstrates our expertise by providing the product with the same qualitative composition varying from the acidic to the neutral pH range.

Crystal structure
Visualization and analyzation of a product’s crystal structure are essential tools for the optimization of our Lohtragon® metal salts. The images from our Scanning Electron Microscope (SEM) and crystal structure elucidation by X-ray Powder Diffraction (XRD) enable us to understand product structures and to adapt the product according to requested functionalities. The three fascinating examples show how different crystal structures can be.
The modification of the crystal morphology influences an extensive range of properties, e.g.:
- Flow properties
- Solubility
- Density
- Reactivity
- Dust behavior and more

Solubility
Is the solubility of a metal salt a crucial factor for your process or final formulation?
High dissolution rates are mandatory for efficient aqueous processes. For formulators of aqueous recipes, the long-term stability is crucial for a good shelf life. Optimized solubility behavior is important for an extended service life.
If your process includes aqueous solutions, you can rely on our expertise to meet your demands. The Lohtragon®’s specialized drying and powder modification processes give you the desired rate of dissolution and an enhanced long-term stability. We give close attention to impurity profiles and can customize our products for your needs.
The exact determination of the crystal water content of a salt is very important, because it stands in direct correlation with the dissolution rate. Your product will be characterized in every aspect, using the highly advanced devices available in the analysis instrument park of Lohtragon®.
Reduced Hygroscopic Effect
Hygroscopicity refers to the property of binding moisture from the environment. If solid substances absorb the moisture, this effect can lead to product lumping – usually undesired.
Based on our Lohtragon® competence in optimizing metal salts, we offer solutions:
- Lohtragon® anti-caking additives reduce hygroscopic effects in your application, such as the specially dried type of our Lohtragon® C36
- Lohtragon® metal salts already flow-optimized and thus more resistant to hygroscopic influences, as e.g. our Lohtragon® V17 type with optimized flow properties
