How to overcome challenging extrusions

By Rosa Mediavilla 27-Jul-2020 07:30:00

Extrusion is a common process used to manufacture different types of ceramic products, for example, face bricks, ventilated walls, floor tiles, special shaped products and many others. Several parameters affect the operation of the extrusion. These parameters include the nature of the raw materials, their particle size, and their plastic behavior, the water content and the additives you use.

Different methods for plasticity measurement of a ceramic material

By Rosa Mediavilla 27-Jul-2017 07:33:00

Plasticity is the characteristic behaviour of a ceramic material to become permanently deformed after the application of an external force. This property is the most characteristic one in clays, and there are some factors that influence the plasticity and they should be considered in plasticity measurements:
