Hydrotalcite is a naturally occurring clay-like mineral. Hydrotalcite was first discovered in the early 19th century by Professor Theodor Scheerer in Norway. Hydrotalcite has been named so because of its high water content and is physical resemblance to talc. Hydrotalcite is a multi-layered hydroxide of Aluminum and Magnesium, with the chemical formula Mg6Al2(CO3)(OH)16•4(H2O). It occurs along with minerals, such as hematite and dolomite, in Serpentinite rock formations. Unlike the much more widely found cationic clays, Hydrotalcite is an anionic clay. The double layered hydroxide structure of Hydrotalcite contains a positive charge in the layers due to the presence of cations and anions are present in the interlayers. Given the weakly bonded nature of anions in the interlayers, Hydrotalcite displays excellent anion exchange properties.
Hydrotalcite has higher affinity for anions with higher charge densities. The calcination of Hydrotalcite at around 400°C removes the anions and the crystalline structure of the Hydrotalcite material collapses to form an amorphous oxide of magnesium, containing aluminum ions in the form of solid dispersed solution. The addition of water restores the layered hydroxide structure of the material, through the sorption of anions. This behavior exhibited by Hydrotalcite has led to the usage of the material for anion sorption application. The use of Hydrotalcite as a solid sorbent for CO2 capture has immense potential given the growing threat of climate change due to global warming.

Hydrotalcite Market: Dynamics
Hydrotalcite is used in a variety of applications, particularly in the chemical and pharmaceutical industry. The anion exchange property of Hydrotalcite is useful the chemical industry. The antacid properties of Hydrotalcite make it significantly useful for healthcare and chemical industry end users. Pharmaceutical grade Hydrotalcite is commonly used for the manufacturing of antacid based suspensions that are used in the treatment of various ailments, such as peptic ulcers, indigestion and gastritis. Also, hydrotalcite finds important applications in the chemical industry as an additive during polymer production. For example, it is used as a heat stabilizer during polyvinyl chloride (PVC) production and is used as a halogen scavenger during polypropylene production.
Hydrotalcite significantly reduces the free acidity of polymers, thus making polymer processing techniques, such as molding and extrusion, free from the fear of polymer degradation. In the power generation industry, Hydrotalcite finds application in the treatment of nuclear waste as is used as a regenerative solid sorbant used for capturing CO2 in coal fired power plants. Thus, the market for Hydrotalcite will primarily be driven by growing demand from the chemical and pharmaceutical industries in near future.
