🌍 Based near Lyon, France, Mathym®, founded in 2013, is specialized in innovative inorganic nanodispersions. Leveraging Baikowski’s global network , Mathym® delivers worldwide industrial-scale nanomaterials with regional support across EMEA, the Americas, and APAC for ceramics, optics & photonics (ophthalmic), semiconductors, energy, and dental applications.
What is Mathym® link with Baikowski®?
Since September 2019, Mathym is part of Baikowski® and bolsters its Portfolio with Nanoparticle Products.
What makes Mathym® nanodispersions unique?
Mathym® develops ultra-small nanoparticles (2–50 nm) that are:
- Highly crystallized and stable
- Agglomerate-free, ensuring transparency and homogeneity
- Dispersible in a wide range of solvents (water, acetone, resins, ethanol, propylene glycol…)
- Scalable at industrial level, with concentrations up to 80 wt.%
- ISO 9001:2015 certified for design, development, manufacturing, and commercialization
This ensures superior transmittance, low viscosity even at high solid content, and reproducibility for high-tech markets.

What industries and applications benefit from Mathym’s nanomaterials?
Mathym® nanodispersions serve cutting-edge industries such as:
-
- Fine ceramics & refractories (low sintering temperature, mechanical strength)
- Optics & photonics (ophthalmic coatings, displays, XR/AR, LED)
- Semiconductors & electronics (advanced coatings, sintering aids)
- Solid-state lighting & energy (ceramic membranes, SOFC)
- Biomedical & dental (radiopacifiers, composites, orthopedic materials)
- Catalysis & environmental applications
- 2D/3D printing & adhesives
The different inorganic parts that have been developped since inception convey sought critical properties (e.g. radiopacity, refractive index enhancement, wear resistance, highly-active catalysts) while their nanosized structures preserve a very high level of transparency and increase their activity when high specific surface areas are at stake.
