What is the purpose of ceramic nanofillers?
Nanofillers are nanoparticles of oxides embedded into a matrix of diverse materials (polymers, resins, metal…). The “classical” nanofillers are meant to lower the cost of a material by replacing a higher value material. Furthermore, ceramic nanofillers have the benefit of strengthen the physical properties of the matrix, namely its mechanical, optical or thermal properties.
Moreover, we’ll show here a new type of nanofillers, designed for high performance applications. We are talking about the agglomerate-free nanomaterial dispersions.
Properties of innovative ceramic nanofillers
The agglomerate-free nanomaterials dispersed in various media are bringing outstanding properties:
- High solid loading
- High transmittance
- Low viscosity.
Mathym® and Baikowski® are producing several nanoparticles, which can be used as nanofillers. Here are some examples including high purity alumina (Al2O3) nano-dispersions, ceria (CeO2) and zirconia (ZrO2), as known as zilight® for Mathym:
The nanoparticles are agglomerate-free and delivered as a suspension. They are also known as nano-dispersions. Well dispersed, these nanoparticles used as nanofillers are solving some paradoxes:
- Radio-opacity / High transmittance, especially for the product YbF3 of Mathym, filyxio®
- Low sintering temperature / High density of the ceramic
- High refractive index / Low light scattering
Hence, the upper properties find their applications in several markets such as medical, technical ceramics, electronics, optronics…
