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.
