Sialon Ceramics

Sialon ceramics, also known as Syalon is a composite of silicon, aluminum, oxygen, and nitrogen. Sialon ceramics are often utilized for their remarkable resistance to high temperatures and corrosive environments. Our thermocouple protection tubes, pump tubes, riser tubes, heater tubes and nozzles are made from Sialon. 

The excellent thermal shock resistance of Sialon ceramics is advantageous in applications such as low pressure diecasting and forging. The material can withstand harsh conditions of molten aluminum, zinc and other non-ferrous metals, ensuring prolonged service life and reduced downtime in the production process. 

Sialon ceramics for engineering applications are established in most parts of the metal industry, especially in the non-ferrous sectors Aluminum, Copper and Brass. The material is also known as Sialon, it offers a wide range of applications:

Smelters and Foundries

• Thermoelement protection tube for both, direct temperature sensing in the metal as well as indirect sensing (environment, e.g. furnace wall or roof)
• Riser tubes for low-pressure-die-casting processes (e.g. Aluminum wheel manufacturers)
• (Immersion-) heater tubes for heating elements, -wires and -coils (protection against erosion and mechanical damages).
• Dosing valves, pistons and armatures for the use in pressurized and highly corrosive flow control systems.
• For thermal engineering where corrosion and thermal shock resistant parts are used and tested for:
  • Thermal shock proof components
  • Thermomechanichally loaded components

Electrical Engineering

• Where highly strong and thermal shock resistant components show improved service behavior: insulators, separation and shielding plates and vacuum and pressure feed through

Optical Engineering

• Where lightweight, highly stiff and long term stable components and structures are needed
  • guiding beams for positioning systems
  • support and frame for lenses
  • housing structures for optical systems
