Advanced Ceramic Materials

International Syalons offer a range of advanced silicon nitride and sialon, alumina, zirconia and silicon carbide ceramics.


At International Syalons we manufacture a family of silicon nitride based sialon ceramicsSyalon, developed for a wide variety of industrial and engineering applications demanding extreme wear, corrosion and thermal resistance.

In addition, we also offer aluminazirconia and silicon carbideceramics which compliment our range of sialons in many applications.

Silicon Nitride / Sialon

The excellent corrosion and thermal resistance of our silicon nitride and silicon carbide ceramics to many acids and alkalis makes them ideal candidate materials for use in the chemical and process industries. For example, as inlets liners in industrial chlorinators.

Alumina

Alumina (or aluminium oxide, Al2O3) is the most widely used advanced ceramic in the world. The reason for this is its combination of good mechanical properties and electrical insulation. ISN offer three grades of high purity alumina ceramics.

Zirconia

Zirconia (or zirconium oxide, ZrO2) is the toughest of all monolith ceramics and offer excellent room temperature mechanical properties. ISN offer two grades of yttria stabilised zirconia, Zircalon 5 and Zircalon 10, and a magnesia stabilised zirconia, Zircalon 20, which has improved thermal shock resistance.

Silicon Carbide

Silicon Carbide (SiC) probably has the best resistance to corrosion in acids and alkalis of all advanced ceramic materials. It also has extreme hardness and high thermal conductivity making it ideally suited as mechanical seals. ISN offer two grades of SiC, a sintered SiC and a reaction bonded SiC.
