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.

  • Silicon Nitride / Sialon

    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.
