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.

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.

Other products and custom designs upon request.

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

” 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. ”

3. Baikowski® supports Handi, Move & Fun

Why the Rally des Gazelles ?

Baikowski® is committed to a strong Corporate Social Responsability policy with values focus on gender equity, disabilities inclusion and innovation promotion. Today, we are supporting LEA crew who is racing on behalf of Handi, Move & Fun at the 32nd Rallye des Gazelles. The event will take place in the Moroccan desert from March 3 to 18, 2023.

Since 1990, the Rallye des Gazelles has been a unique, responsible and citizen race, that gather women from 18 to 71 years old each year in the Moroccan desert. It is based on three pillars: woman commitment, respect of the environment and positive citizen actions.

The racers, selected on their motivation and a non-discrimination basis on grounds of nationality, experience, background or age, are involved in an adventure that:

• promote tolerance, solidarity and perseverance values,
• respect the country crossed thanks to the solidarity actions carried out,
• is environment friendly. In fact, The Rallye Aïcha des Gazelles is the only race certified ISO 14001 since 2010 in the world.

Handi, Move and Fun & Baikowski® common values

Freedom, Equality, Accessibility!

Created in 2022, Handi, Move & Fun aims at enabling each child with a physical, mental or sensory disability to practise sport and make their rehabilitation playful at the same time. The association allows them to benefit from specific equipments and to rediscover the pleasure to take part in sport activities with their peers without disabilities, especially their family!

The association has various missions such as:

• raising awareness among the public and parents of children with disabilities on the issue of accessibility and inclusive sport,
• giving tips and advice to adapt activities to children with disabilities,
• raising funds to subsidize sports sessions thanks to a specific equipment rental or purchase for all needed families, especially with a limited budget.

The nano-dispersion zilight® from Mathym®

Since zilight® is commercially available, it has been a growing success for our start-up Mathym. In fact, zilight® meets high-end applications where small particle size is key and do not have real competitive products. Thanks to its high refractive index, this product is mainly targeted at the optics and photonics markets. However, the energy & environment markets should benefit from its properties for demanding and emerging technical applications such as fuel cells.

Technical aspects of the nanozirconia product zilight®

zilight® is available either doped (with yttria (YSZ), CeO2, Gd2O) or undoped (ZrO2). Mathym’s know-how lead not only to high-end zirconia nanoparticles, but also to state-of-the-art nano-dispersions. zilight® is available dispersed in various solvents & resins:

• water, alcohol, polyol, acetone, MEK
• select organic solvents
• methacrylate or acrylate-based resin
• silicone oils, customer specific monomer mixture, e.g.: epoxy & fluorene (under development)

The solid content can go up to 70% depending on the dispersion medium.

zilight® nanomaterial applications

zilight® exhibits a very high refractive index, ideal in the design of high-end optical materials. Moreover, zilight® preserves a high level of transparency in nanocomposites. It will be your favorite nanofiller for encapsulation materials, improving visible LED device efficiency. It can also act as an additive for advanced ceramics (sintering aid), for display materials (refractive index enhancer), or for coatings (scratch resistance).
