Advanced Ceramic Solutions for Extreme Environments

With nearly forty years experience in the production and development of advanced engineering ceramics, International Syalons (Newcastle) Ltd.  are experts in the field. We are based near Newcastle upon Tyne in the North East of England and are the UK’s leading manufacturer of sialon and silicon nitride based technical ceramic products and powders.


Syalons are advanced silicon nitride based technical ceramics and are amongst the strongest and most durable ceramic materials known. Their outstanding properties allow them to compete with other engineering ceramics and refractories such as zirconia (ZrO2), alumina (Al2O3) and silicon carbide (SiC) in many diverse industrial applications. Syalons, also known as SiAlONs, were the world’s first commercially available advanced ceramic alloys.


In addition, we can offer a range of advanced technical ceramic solutions such as alumina, zirconia and silicon carbide and can offer a complete solution to your advanced ceramic requirement. Please call +44(0)191 2951010 or email for an initial consultation with our technical sales team or send us a Request for Quote.
