These special features elevate refractories at a unique technical position in the hierarchy of materials, a position that is a combination of ceramics, geology, mineralogy, and engineering composite technology. Unfortunately, this special blend of science and technology has not always been a particularly active area for fundamental research.
Vermiculite. Vermiculite is the geological name given to a group of hydrated laminar minerals which are aluminium-iron-magnesium silicates, resembling mica in appearance. Rock and other impurities are removed from the crude ore which is then crushed and sorted into sizes. Vermiculite is a safe inert material and is light in colour.

Vermiculite Vermiculite is a high-charge 2:1 phyllosilicate clay mineral. It is generally regarded as a weathering product of micas. Vermiculite is also hydrated and somewhat expansible though less so than smectite because of its relatively high charge. Granular clay absorbents, such as vermiculite…
