Custom and ready-to-use oxides

Designing easy-to-use solutions in order to meet our customer needs, processes and applications, is part of our know-how and DNA. Indeed, Baikowski® provides various ready-to-use oxides including:

spray-dried powders and slurries.

Ready-to-use and ready-to-press oxides

Powder deagglomeration

Several methods of powder deagglomeration are used according to the desired particle size and distribution.

  • Jet milling is the easiest way to produce middle-size milled powders that offer a large size distribution composed of one or two populations.
  • Ball milling is a size reduction technique using only mechanical forces that enables a lower size distribution than jet milling.
  • Wet milling allows the production of smaller particle size and a narrower size distribution versus other milling methods.

Thanks to these different deagglomeration processes, Baikowski® has not only the ability to expand its product portfolio with products that offer specific physicochemical properties and a higher sintering reactivity, but also to control dispersion, morphology, composition, homogeneity at the powder grain level.

Ready-to-use and ready-to-press oxides benefits

Wet milling enables the design and production of ready-to-use slurries, spray-dried powders with or without binder and freeze-dried solutions.

Among the various benefits of ready-to-use or ready-to-press solutions, we can mention a
better flowability, an improved behavior while pressing ceramics and a perfect consistency of your final product.

Generally speaking, slurries and spray-dried powders have helped our customers develop unique solutions in various markets including energy, battery, health or 3D printing, by allowing the design of innovative materials.

As noticeable examples:

  • spray-dried powders have considerably improved the ceramic injection molding process by making the production of feedstocks easier.
  • ready-to-use slurries have been a major breakthrough in the Semicon industry by ensuring the absence of large particle counts in the Chemical Mechanical Planarization (CMP) process.
  • YbF3 nano-dispersions, already dispersed in the dental formulations, have allowed outstanding performances for restorative applications. Mathym®, the producer of nano-dispersions within the Baikowski ® group, is a key actor of this market.

Baikowski® ready-to-use and ready-to-press offering

Taking into account all of the above, our BA15 and GEA6 high purity alumina products, as well as our ZTA/ATZ and spinel solutions are commercially available in slurry, spray-dry and ready-to-press forms.

Analytical skills & tailor-made oxide solutions

How do we characterise and design powders and slurries thank to our in-house analytical skills?

Listen to Livia MARRA explanations, our Senior Project Manager, in this short video.


Get updated and relevant information


” Hello, my name is Livia Marra. I have been working for Baikowski since 2012. I started as a trainee engineer before becoming a R&D project manager.

Baikowski is a 115-year-old company, specialized in high purity alumina and many other oxide powders.
Our headquarters and manufacturing plant are located in Poisy, in France. We have another manufacturing plant in the United States, a joint venture in Japan and several sales offices around the world.
Mathym joined us in 2019 and is specialized in nano-dispersions. This branch of Baikowski enables us to expand our product offering and expand in new markets such as the dental one.

We address several markets including automotive, electronics, medical, watch & jewelry, aerospace & defense and cover applications in ceramics, polishing and batteries.
With so many high-end applications, we have great analytical needs, either to respond to our client demands, or to anticipate their needs. That’s why we are always looking for ways to improve our products characterization. For this purpose, we bought the “Calvet Pro of Setaram” that provides us thermogravimetric and DSC analyses.

As an example, we use it to measure the moisture absorption of our alumina powders. In lithium-ion battery applications, we know we can’t have water as it would interfere with lithium metal. By figuring out the mass uptake by a powder during its exposure to a humidity air flow, we are able to calculate the absorption rate of a powder.

For catalytic applications, the device allows to inform customers on the acidity/basicity of our products, their ability to absorb different type of gas.

We can also assess the mass lost of a powder with blinder system or the decomposition temperature of a special product. In addition, we can carry out a synthesis knowing the transformation temperature of the powder.

As a conclusion, thanks to the flexibility of this device and our analytical skills, we can meet a lot of our customers’ expectations. ”

Batteries European Partnership – BEPA

What are Batt4EU and the BEPA?

Batt4EU is a battery-focused partnership which was initiated under the Horizon Europe Programm. This European partnership aims at reaching a competitive and sustainable industrial value-chain for batteries inside the old continent. It brings the vision to drive the transformation towards a carbon-neutral society.

The BEPA stands for Battery European Partnership Association.


This association constitutes the private side of Batt4EU – the public side being the European Commission. The BEPA regroups all the battery stakeholders from the European Research Community. It was created in 2020.

Baikowski joined the BEPA in early 2021. In december 2021, there were already 180 members.

Advanced materials & manufacturing BEPA working group

The main mission of Technical Working Groups (TWGs) is to identify, prioritize and draft the Research & Innovation topics which will be submitted to the European Commission as recommendations for the next Horizon Europe Work Programs. There are six TWGs in total, in order to cover the whole value chain.

Baikowski is part of the 2nd Technical Working Group : Advanced materials and manufacturing.

By being part of the BEPA, Baikowski goes one step further into the research in the battery field.

The influence of HPA in the Li-ion battery

Indeed, we are convinced that fine oxides, including high purity alumina, will play a key role in the future of the battery. This future is full of challenges; make the battery safer, smaller, last longer and increase its energy density. We believe that our products can play a part in taking up those challenges thanks to the high level of control we have on their properties.
Let’s take an example of downsizing. First of all, we highly control the particle size and size distribution of our powders. If our fine particles of Al2O3 are used as a filler or as coated layer for Li-ion battery separator, then the thickness of the Al2O3 layer is also closely monitored. In the end of the day, the thickness of the finished separator is also highly controlled and contributes to downsizing the battery cell.

Ceramic nanofillers

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, titanium dioxide (TiO2), ceria (CeO2) and zirconia (ZrO2), as known as zilight® for Mathym:

Mathym Nanoparticles dispersed Al2O3, TiO2, CeO2, ZrO2

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:

filyxio®, YbF3 nanoparticles Mathym

  • 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…
