International Syalons supplies advanced silicon nitride, zirconia, alumina and silicon carbide ceramic solutions for diverse chemical & process industry applications, utilising their outstanding chemical and thermal stability.
Advanced ceramics combine high strength and toughness with extreme hardness to give excellent wear resistance. Materials such as silicon nitride and sialon and silicon carbide also have excellent high-temperature properties and are resistant to corrosion by many acids and alkalis which allows them to find numerous wear resistance applications. For example, Syalon 101 possesses an outstanding set of physical properties such as high strength, toughness and hardness and is pre-eminently suitable for couples used in sliding wear or as dewatering foils in paper manufacture, whilst the superior hardness of Syalon 050 allows it to be of particular benefit in many wear applications, such as sand blast liners and Sycarb is widely used as a mechanical seal.
Zircalon 10, an yttria partially stabilised zirconia, although generally not as wear resistant as Syalon or Sycarb, possesses superior toughness making it the material of choice for many wear applications where impact is experienced. For example, Zircalon has found wide use as weld locations pins in resistance welding of captive nuts to sheet metal.
Below are a selection of common industrial wear applications of our advanced engineering ceramics:

Syalon 101 thermocouple protection sheaths are becoming the industry standard in non–ferrous metal foundries. They possess outstanding thermal shock resistance, are non–wetting and suffer no degradation in contact with aluminium and its alloys.

The benefits of Syalon 101 for thermocouple sheaths applies equally to heater and riser tubes. International Syalons manufacture a wide array of heater and riser tubes to suit most requirements in the non–ferrous molten metal foundry business.

Silicon nitride and sialon offer additional strength and wear resistance compared to low-grade ceramics, especially in high temperature or corrosive environments, and is ideally suited for use in protective plates for demanding sensor applications.

Sialon ceramic weld rolls eliminate material pick-up, improving the the surface finish of non-ferrous metal high frequency welded tubes whilst offering higher speed processing and greatly increased service life over conventional tool steel rolls

silicon nitride and sialon advanced ceramic die inserts are used for the extrusion and drawing of copper, brass and nimonic alloys and are known for their excellent wear properties, including high strength, hardness, toughness, and thermal stability.

Silicon nitride and zirconia weld location pins are used widely throughout the automotive manufacturing industry, where high volume robotic and semi-robotic spot welding requires high strength, fracture and wear resistant precision welding location and control pins.

Sialon and zirconia provide the high temperature strength and non-wetting properties necessary for metal casting, extruding, and welding.

The temperature and corrosion resistance properties of sialon have been utilised in a range of foundry products for molten metal handling.

Silicon nitride, zirconia, and alumina ceramic offer outstanding refractory properties and thermal stability.
