Technical Ceramics Materials

Technical ceramics promote exceptional performance in some of the world’s harshest working environments, creating new engineering opportunities in age-old applications and emerging markets.

From elementary ceramics to advanced piezoelectrics, the world of technical ceramics has expanded rapidly over decades of concerted research and development in materials science and industry. Today, the best technical ceramics suppliers can offer precision engineered materials with highly specialized performance properties suited to demanding heavy industry and cutting-edge high technology applications alike.

Though undeniably diverse, technical ceramics can largely be categorized as either oxide ceramics or non-oxide ceramics. At International Syalons, we manufacture and supply non-oxide technical ceramics such as silicon nitride, sialons, and silicon carbide, alongside oxide ceramics including zirconia and alumina. As one of the UK’s leading technical ceramics manufacturers, we engineer each of these materials for distinct end-use characteristics, by carefully selecting specific high-quality raw materials and employ a range of processing routes including carefully selected green forming methods, advanced sintering techniques, and precise diamond grinding to achieve the highest-quality finished parts to meet specific end-user demands.

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.

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.
