Croda advanced materials for advanced ceramics

Advanced ceramics

Increasingly prevalent digitalization and electrification today have led to a growing demand for ceramics with application specific properties. Advanced ceramics are employed for their mechanical, chemical, and thermal stability. Advanced ceramics are inorganic, non-metallic materials which can be used in a variety of niche high-end applications such as:

  • Ceramic tape
  • 3D printed ceramics
  • Ceramic fibre composites
  • Solid oxide fuel cells components
  • Piezo-electric ceramics
  • Multi-component ceramic slurries

Our innovations for advanced ceramics

To keep up with the ever-increasing demand placed on advanced ceramics, there is a constant need for innovation. We offer several products that bring key benefits like:

  • Decreased viscosity
  • Rheology control
  • Narrow particle size distribution
  • Stable dispersions
  • Low impurities
  • Broad solvent range applicability

Ceramics are often processed via slurries to allow for easier manufacturing. Slurry behaviour is dependent upon both particle and solvent characteristics. The surface charge, size, shape, crystallinity and density of the particle along with the solvent polarity, density and pH (if applicable) all influence the behaviour of the ceramic slurry.

With knowledge of these properties, the correct additives can be designed and selected to boost the properties of both the ceramic slurry and the final ceramic. Our technology solutions and guidance are based on our long-time expertise in dispersion mechanisms and flow characteristics, delivering a performance advantage in your ceramic applications.

High performance dispersants and rheology modifiers by Croda help to improve ceramic density, thereby enabling miniaturisation of ceramic based electronic components.

All of this can be achieved through formulation of slurries in water, polar/non-polar solvents, or resin with:

  • Increased solids loading at reduced viscosity
  • Controlled rheology
  • Improved dispersion stability and uniformity
  • Low impurities

Dispersants for reliable advanced ceramic slurries

Dispersants interact with the surface of particles and prevent other particles from coming closer. This can be done by electrostatic, steric or electrosteric means.

Matching the dispersant with the particle that you are trying to disperse and the solvent that is to be dispersed in, is the best way to find the appropriate dispersant. We can are happy to advise you on this so feel free to contact us.
