Ceramics
Materials at the heart of industrial applications
Technical ceramics are now used across a wide spectrum of industrial applications where reliability, resistance to harsh environments and long-term performance are critical. Thanks to their intrinsic properties, they often represent the go‑to solution when metals or polymers reach their limits.
Technical ceramics are obtained from mineral raw materials through various shaping processes (casting, extrusion, pressing, injection, machining, 3D printing, load‑assisted sintering, etc.) and then consolidated through a thermal treatment.
They play a key role in the energy, electronics, aeronautics, defence, health, automotive and construction sectors, but also in the luxury, creative and fine crafts markets, where their functional performance goes hand in hand with high aesthetic value.
Applications in strategic sectors
AEROSPACE
Ceramics are used in environments exposed to extreme thermal and mechanical stresses, such as foundry cores, thermal protection, turbine components, high-temperature sensors, space-grade mirrors, and specialized structural parts. Their exceptional heat stability and outstanding wear resistance make them ideal materials for applications where most others would fail.
DEFENSE
Technical ceramics are used in systems that demand exceptional resistance to harsh environments and extreme stresses, from ballistic armor and radomes to tactical propulsion, optronic components, and advanced sensors. Their low density, high hardness, and outstanding thermal stability make them essential materials for critical equipment and high‑performance protection technologies.
ENERGY
In energy systems, ceramics play a key role in applications that demand exceptional resistance to heat, corrosion, and harsh operating conditions. They are used in fuel cells, industrial furnace components, high‑temperature insulators, and advanced sensors. Their thermal stability, long‑term durability, and resistance to corrosive environments help boost energy efficiency and extend the lifespan of critical equipment.
ELECTRONICS AND PHOTONICS
Technical ceramics serve as essential insulating substrates, hermetic housings, thermal dissipators, and even active components such as capacitors, 5G antennas, and RF filters. They are also key building blocks in high‑power lasers, optical fibers, and military‑grade optics. Their combination of miniaturization capability, high reliability, and efficient thermal management makes them indispensable for advanced power electronics and high‑frequency systems.
HEALTHCARE AND MEDICAL DEVICES
Technical ceramics are valued in the medical field for their biocompatibility and exceptional wear resistance, making them suitable for orthopedic and dental implants as well as surgical instruments that require high chemical and dimensional stability. These properties allow them to perform reliably inside the body and in demanding clinical environments, where long‑term durability and precision are essential.
AUTOMOTIVE AND MOBILITY
echnical ceramics are used in engine components, braking systems, sensors, and embedded electronics such as converters for electric vehicles. Their combination of low weight, high‑temperature capability, and exceptional durability helps reduce overall system mass, support higher operating temperatures, and extend the lifespan of critical components.
LUXURY, CREATION AND CRAFTS
Technical ceramics extend beyond industrial uses to offer refined surface quality, dimensional stability, and remarkable design freedom, making them highly sought after in watchmaking, product design, interior architecture, and contemporary creative work. They enable a unique combination of rich colour diversity, technical performance, and aesthetic precision, allowing designers and creators to merge functionality with visual excellence.
