Water Of Plasticity In Ceramics

It s also known as the quality or state of being plastic.

Water of plasticity in ceramics.

Start studying ceramics 1 homework 1 2 quiz. A capacity for being molded or altered. Plasticity refers to how flexible a clay or clay body is. 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.

In the forming of ceramic materials the plasticity concept is commonly used. It s the property of clay that got us hooked on it in the first place. Biokeram has found an effective way to improve low plasticity ceramics. The fine platy morphology of clay particles is used to advantage in the forming of clay based ceramic products.

Plasticity arises by virtue of the plate shaped clay particles slipping over one another during flow. This term is related to a particular mechanical behavior when clay is mixed with water. It is defined as the ratio between the water responsible of tile contraction and the total water. Plasticity plasticity in ceramics is a property exhibited by soft clay.

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. 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. Bigot curves show this information. Learn vocabulary terms and more with flashcards games and other study tools.

Depending upon the amount of water added clay water bodies can be stiff or plastic. When the force is removed or reduced the shape is maintained. It is the property a substance has when deformed continuously under a finite force. 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.

Any particular clay s plasticity is greatly influenced by the clay s particle size water content and aging. Force exerted effects a change in shape and the clay exhibits no tendency.
