Water of plasticity in ceramics.
Plasticity is the outstanding property of clay water systems.
This term is related to a particular mechanical behavior when clay is mixed with water.
Measuring of plasticity is based on the principle of impact deformation using a sample with a defined diameter and height deformed by a free falling plate with a given mass.
Plasticity depends a lot on particle size mineralogy organics salts etc but it s a key parameter in the extrusion of ceramic compositions required for the production of very different materials.
Caused by just the right mixture of water and particle size plasticity is what transforms dry cracky clay like in the image above into a workable clay body.
Any particular clay s plasticity is greatly influenced by the clay s particle size water content and aging.
It is defined as the ratio between the water responsible of tile contraction and the total water.
Biokeram has found an effective way to improve low plasticity ceramics.
Force exerted effects a change in shape and the clay exhibits no tendency.
Bigot curves show this information.
Traditional ceramics traditional ceramics forming.
In the forming of ceramic materials the plasticity concept is commonly used.
A capacity for being molded or altered.
Water is the most important ceramic material it is present every body glaze or engobe and either the enabler or a participant in almost every ceramic process and phenomena.
It s also known as the quality or state of being plastic.

Mineralogical composition particle size distribution organic substances and additives can affect the plasticity of clays.
Plasticity arises by virtue of the plate shaped clay particles slipping over one another during flow.
Plasticity plasticity in ceramics is a property exhibited by soft clay.
Depending upon the amount of water added clay water bodies can be stiff or plastic.
The fine platy morphology of clay particles is used to advantage in the forming of clay based ceramic products.
Plasticity refers to how flexible a clay or clay body is.
