Center for Technology Transfers in Ceramics

The Centre de Transfert de Technologies Céramiques (CTTC) is a private Research and Technology Organisation (RTO) specialised in the field of technical ceramics materials and shaping processes. CTTC offers various services mainly consisting of contractual Research & Development, scale-up, industrial transfer, complemented by design office services, expertise, material characterization (EXALYSES by CTTC laboratory), and training (Qualiopi certification). The Centre, dedicated to additive manufacturing for ceramics and also multimaterial components, has all necessary skills (processes of digitizing and modelling, feedstock formulations, process parameters, post-treatments and characterization) to support industrial developments in their innovation approach. CTTC customers come from several industrial sectors such as health industry, electronics, energy, space, aeronautic, luxury…

The ADDICERAM project, included in the CTTC resourcing programs CERA+ (2017-2019) and CERA2+ (2020-2022), is dedicated on layer-by-layer additive manufacturing technologies such as Binder Jetting and Micro-Extrusion processes. This project in collaboration with a regional laboratory (IRCER, CNRS) targets different applications (optics, aeronautics, energy).

From September 2022 to September 2022

The CERACELL project, included in the CTTC resourcing programs CERA+ (2017-2019) and CERA2+ (2020-2022), is dedicated on the production, recovery and energy storage integrated into mobile devices, thermal protection of aeronautical alloys and tribological coatings for prostheses. It relies mainly on the development of the Aerosol Deposition Method (ADM) technology (INPACT technology - CTTC patent) and on partnerships with several academic teams who provide their expertise on materials and systems.

From September 2022 to September 2022


R&D studies
The R&D team of the CTTC accompanies enterprises in their innovation and research projects in the field of technical ceramics. To do so, the CTTC gathers several tools such as technological ressources, manufacturing methods, a wide range of caracterization devices allowing the team, composed of technicians, engineers and PhDs with different skills and specialities to meet your expectations and provide responses tailored to the needs of their customers. The R&D service of the CTTC conducts around 40 studies each year for well-known companies such as: SAFRAN, Saint-Gobain, Airbus, Imerys CEA,...
Analysis and measurement
The CTTC offers a large range of tools to characterize ceramic materials at different step of processes from raw materials to finished products. According to your need, whether you want to test or understand the behavior of a product under certain conditions or you just want to compare the properties of parts, the CTTC's ceramic analysis lab is equipped with a full laboratory with multiple characterisation facilities among which one can find physical-chemical, mechanical, microstructural and thermal analyses.
As a recognized training institution, CTTC offers its skills across a range of unique training courses which combine theory and practice, with an emphasis on shaping processes (dry, plastic and liquid), characterizations, raw materials and heat treatment. The CTTC offers a whole panel of courses arranged as a set of theoretical presentations, demonstrations and practical applications of our industrial equipment. This allows engineers and technicians to learn the characteristics of the manufacture and implementation of ceramics.
Expertise and technical assistance
From the writing of the specifications up to the start-up of production lines, CTTC provides customers with expertise and personalized technical assistance. Our consultants in ceramics gives: a better understanding and grasp of projects, help in decision-making to manage projects more rapidly and effectively. The CTTC offers a custom-made method comprising : an industrial site audit, state of the art technical expertise, testing and analytical options to clarify any problems, support from its partners.


Alumina ceramic Ink IJ-AL14
The IJ-AL14 ink is a High Temperature Co-fired Ceramic (HTCC) ink suitable with ink jet printing provided by the CTTC . It contains 10 to 30% of alumina particles with a mean size below 250 nm dispersed in an organic solvent. The IJ-AL14 ink shows a viscosity of 30 mPa.s and a surface tension of 30 to 35 mN/m. It can be printed after sieving at 8 µm and dried with NIR and controlled humidity and room temperature. The curing conditions of the IJ-AL14 ink are as followed : 60 minutes at 1600°C.
Zirconia ceramic Ink AJ-YSZ40
The AJ-YSZ40 ink is a zirconia ink suitable with aerosol jet printing provided by the CTTC. It contains 35 to 45% of solid contents with a mean particle size below 1,5 µm dispersed in an organic solvent. The AJ-YSZ40 ink shows a viscosity of 150 to 200 mPa.s. This ink requires agitation before printing and a drying under atmospheric conditions. The sintering of the AJ-YSZ40 ink is performed during 60 minutes between 1200°C and 1400°C.
Tungsten metal ink AJ-W65
The AJ-W65 ink is a tungsten ink suitable with aerosol jet printing provided by the CTTC. It contains 60 to 70% of solid contents with a mean particle size below 100 nm dispersed in an organic solvent. The AJ-W65 ink shows a viscosity of 150 to 400 mPa.s and a resistivity of 0,05 Ohm/[]. This ink requires planetary stirring before printing and a drying at ambiant air. The sintering of the AJ-W65 ink is performed during 60 minutes at 1600°C under a reducing atmosphere (Ar/H2).
