Jan 01, 2018· Solgel is a method for producing solid materials from small molecules. In this chemical procedure, the sol (or solution) gradually evolves toward the formation of a gellike diphasic system containing both a liquid phase and a solid phase, the morphologies of which range from discrete particles to continuous polymer networks ().Ultrafine and uniform ceramic powders can be formed by precipitation.
The main constituent, which is the determinant factor in the clay''s properties, is the clay mineral montmorillonite. This in turn, derives its name from a deposit at Montmorillon, in Southern France. Bentonite is a clay generated frequently from the alteration of volcanic ash, consisting predominantly of smectite minerals, usually montmorillonite.
