Definitions for "Deflocculation"
The liquid clay used to cast molds is called slip. For slip to cast walls of even thickness the clay particles must be equally suspended in water without clumps. This is accomplished by chemically charging the clay and water with electricity. A small amount of sodium silicate will give the clay and water opposing electrical charges. This prevents the clay from settling to the bottom of its container over time. Too much sodium silicate will cause the slip to become gelatinous. This state is called"thixotropy"
The separation of the aggregate particles into the individual particles, as in a slip in which the proportion of particles in suspension is increased through the reduction in particle size.
State or condition of a dispersion of a solid in a liquid in which each solid particle remains independent and disassociated with adjacent particles. A deflocculated suspension shows zero or a very low yield value.
