Deflocculation Demand - DFDM

This test procedure was employed in the Foresight Ceramic Database and now is available for those having an account at Insight-Live.com. Accumulating test data using the variables defined in these procedures enables us to create tools that enable you to compare the physical properties of materials and recipes.


Refers to the percentage of deflocculant required to bring a slurry to a specific degree of flow and a specific density. For example, a data sheet might specify:

"Measured at 305 degrees TTV, fitted with 30swg wire and 11/16" bob (equivalent 5 poise). Slurry density 1620 g/l = solids concentration 62% use 3:1 Na2SiO3(c.100):Na2CO3"
