Technical Ceramics – Silicon Carbide

Dursic is a silicon carbide wear-resistant ceramic known for its extreme hardness, very high chemical resistance and exceptional thermal stability.

This high-performance material enables the manufacture of large components and complex geometries to provide durable protection for areas exposed to the most severe abrasion.

With a Mohs hardness of 9, thermal resistance exceeding 1350°C and complete resistance to corrosion, Dursic stands out as the ultimate solution for critical industrial environments.

Manufacturing process :

Dursic is produced from purified silicon carbide, molded or machined according to the required shape, then treated at high temperature to ensure a dense, stable structure with very high mechanical resistance, even for large components.

Fixing method :

Depending on the geometry and service constraints, Dursic parts can be installed :

• by bonding with suitable resins,
• by bolting or mechanical systems,
• via inserts integrated during molding,
• or combined with a steel/rubber support depending on the application.

Main Applications of Dursic

Dursic is used in environments exposed to extreme abrasion, severe chemical attack or very high temperatures. It is particularly suited for:

Chutes
Hoppers
Cyclones & hydrocyclones
Piping systems (pneumatic or hydraulic conveying)
Chemical & food processing industries
Cement plants
Mines & quarries

Advantages of Choosing Dursic

Thanks to its exceptional hardness, Dursic provides unmatched abrasion resistance, far exceeding traditional ceramics.

Its complete chemical stability — even against strong acids such as hydrochloric, sulfuric or hydrofluoric acid — makes it a reliable material in the most corrosive environments.
Its very low porosity, combined with remarkable thermal behavior, allows it to withstand extreme temperatures without deformation, including under thermal shock.

The manufacturing process enables complex shapes and large components, making it easier to adapt Dursic to any type of industrial equipment.

As a high-end solution, Dursic provides ideal protection to extend the service life of critical installations exposed to severe wear, corrosion or intense thermal stresses.
