Additive In Ceramic Processing
Important of additive
to fix flow of properties and other required in ceramic fabrication.
very required in completion of ceramic products.
to wet and provide viscous media between the ceramic particles.
dissolve the salt or compounds.
Example: trichioroetnylene, alcohol, filtered petroleum, melt wax.
enhanced repulsive via electric charge
prevent particles sticks to each other
encourage particle to agglomerate via reducing the repulsive.
Decrease liquid surface tension
To raise the wetting & particle distribution
Requirement to choose :
lyophilic group : pole group that will attract poles liquid molecules
lyophobic group : non-polar
water-hydrophilic & hydrophobic
Used in Ceramic processing
*If surfactant +ve charge, coating +ve charge will form seperation. Automotive industry, surfactant & coating different charge so that pull together.
Entrapped polymer molecule at particle will form a bridge between them and bond them to each other.
Enhance product strength
To change thin layer binder viscoelastic properties
