Stable vermiculite dispersions which are substantially free of settling and a method of preparing same are provided. The dispersions are obtained by treating the vermiculite platelets of which the dispersion is comprised with an anionic chelating agent. The anionic chelating agent enhances the rate and degree of swelling of the vermiculite in an aqueous medium.

It is because vermiculite has an inhibiting effect on the decomposition of CaSO 4. Meanwhile, the swelling vermiculite inhibits the formation of Na 2 SO 4 and restricts the corrosion. The blended vermiculite brings more Mg 2 SiO 4 with high ash melting point into the ash deposit, and that reduces the viscosity of inner ash.

Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and commercial furnaces can routinely produce this effect. Vermiculite forms by the weathering or hydrothermal alteration of biotite or phlogopite. Large commercial vermiculite mines currently exist in the United States, Russia, South ...

Vermiculita. La vermiculita es un mineral formado por silicatos de hierro o magnesio, del grupo de las micas . La vermiculita se describió por primera vez en 1824 por una ocurrencia en Millbury, Massachusetts. Su nombre deriva del latín vermiculare, 'por criar gusanos', por la manera en que exfolia cuando se calienta.
