Bentonite is a naturally occurring clay primarily composed of montmorillonite, a mineral belonging to the smectite group. It has a layered structure and a high cation exchange capacity.<\/p>
From a physicochemical perspective, bentonite is highly hydrophilic, has a large specific surface area, and can swell significantly when in contact with water. It is capable of absorbing large amounts of liquid and forming highly viscous gel-like suspensions even at low concentrations.<\/p>
Key physical properties of bentonite include:<\/p>
1. High absorption capacity \u2013 it can absorb several times its own weight in water, forming a gelatinous mass<\/p>
2. Plasticity \u2013 it enhances the plasticity of ceramic mixtures, improving their workability<\/p>
3. Thixotropy \u2013 bentonite suspensions become more fluid when stirred and return to a gel state when left to rest<\/p>
4. Large specific surface area \u2013 due to its lamellar structure, it offers extensive surface contact<\/p>
In the ceramics industry, bentonite is used to improve the plasticity of clay mixtures, aid in shaping processes, and increase the mechanical strength of unfired products.<\/p>
Specifically, in tile manufacturing, bentonite helps optimize the rheological properties of ceramic slurries, contributing to better application of glazes and decorative finishes.<\/p>","protected":false},"excerpt":{"rendered":"
