Heptahydrate crystals carry seven molecules of water. Semi dried "sugar crystal" grades have part of that water removed, giving a free-flowing crystal with slightly higher metal content. Dried powders have most of the water removed, giving the highest Fe or Mg content per kilogram and lower freight cost per unit of metal.

It depends on your process, dosing method and the metal content you need. Share your application with us and we will recommend the most suitable and cost-effective grade.

Yes. Samples, technical data sheets and batch-wise certificates of analysis are available on request.
