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 ceramics, Syalon, developed for a wide variety of industrial and engineering applications demanding extreme wear, corrosion and thermal resistance. In addition, we also offer alumina, zirconia and silicon carbide ceramics which compliment our range of sialons in many applications.
International Syalons offer 5 grades of Syalon which offer a broad range of properties from outstanding strength and toughness, high hardness, high temperature strength, thermal shock resistance, resistance to attack by many molten metals and unique electrical properties.
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 (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 (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.
