CERAMICS
1. ALUMINA
Alumina is one of the most widely used ceramics. It has high resistance to abrasion and corrosion, excellent hardness, high mechanical strength and good dimensional stability.
Grades
- Al2O3 (88 à 99.9 %)
- Steatite
- Mullite
- cordierite

2. BORE NITRIDE
Boron nitride is characterized by an excellent resistance to corrosion in a reducing atmosphere. Its use is mainly extended due to its good resistance to thermal shock, its high electrical resistivity and its excellent machinability.
- Hot-pressed boron nitride: various grades are available and recommended according to their application characteristics (high mechanical resistance, moisture resistance, chemical and electrical properties ...) Available in bars, plates and parts Machined on plan.
- Boron nitride powder (various compositions and particle sizes).
3. ALUMINUM NITRIDE
Shapal-M is a high-purity, low coefficient of thermal expansion (4.4 ppm / ° C), good thermal conductivity (90 W / m) . ° C) and good machinability.
Availability
Plates, sheets, bars, machined parts.

4. BORON CARBIDE
Boron carbide (B4C) has interesting physicochemical properties, generating a wide range of applications:
Availability
Hot-pressed powders, granules or semi-finished products.
- Boron carbide is extremely hard and has a high wear resistance, hence its use in the manufacture of blast nozzles and nozzles; It is used in powder form as an abrasive for polishing or in water jet cutting.
- Because of its high neutron efficiency, boron carbide is used as a neutron absorbent in nuclear reactor control rods.
- Its high hardness, high modulus of elasticity and low density make boron carbide very effective in stopping high-speed projectiles. It is therefore frequently used as a ballistic shielding material.
Availability
Hot-pressed powders, granules or semi-finished products.
5. MACOR
MACOR is a machinable vitro-ceramic (milling, turning, drilling ...) with very precise tolerances by conventional means (carbide tools preferably), thanks to a bi-phase microstructure (mica crystals in a glass matrix).
Availability
Machined parts on plan, bars, plates.
