Abstract: An X-ray amorphous magnesium carbonate is disclosed that is characterized by a cumulative pore volume of pores with a diameter smaller than 10 nm of at least 0.018 cm3/g, and a specific surface areas of at least 60 m2/g. The X-ray amorphous magnesium carbonate is produced by reacting an inorganic magnesium compound with alcohol in a CO2 atmosphere. The X-ray amorphous magnesium carbonate can be a powder or a pellet and acts as a desiccant in, for example, production of food, chemicals or pharmaceuticals.

Abstract: The present invention relates to a highly porous magnesium carbonate and method of production thereof. The method according to the invention provides a way to control the average pore size of the highly porous magnesium carbonate by controlling the agglomeration of CO2 in a powder formation step in a sol-gel based production process. The method makes it possible to adapt the average pore size to a second material, for example a pharmaceutical compound, to be loaded into highly porous magnesium carbonate. The highly porous magnesium carbonate according to the invention comprises mesopores with an average size in the range 10-30 nm.

Abstract: The present invention relates to a getter material and a production method thereof. The method enables control of a sol-gel process so that a nanoparticle getter material with intrinsic nanoparticles in a size range from 10 nm to 1 ?m can be produced with accurate size control. The intrinsic nanoparticles of the getter material are composites of magnesium oxide and amorphous magnesium carbonate, substances that have properties that are highly interesting for getter applications. The composition ratio of magnesium oxide to magnesium carbonate may preferably be in the range from 5:95 to 50:50.
