The demanding specifications of shot blasting equipment require high-performance materials capable of withstanding sustained pressures and temperatures. Conventional metals with outstanding hardness values are routinely used to prepare tough shot blast nozzle linings, but they are incapable of competing with the unique mechanical stability of advanced ceramics like silicon nitride.
This article will explore the capacities of advanced ceramic shot blast nozzles in more detail:

Silicon nitride is one of the most advanced ceramic materials currently manufactured, providing outstanding hardness levels that are rarely matched by conventionally-manufactured components. Most silicon nitride products are electrically insulating, which provides certain industrial benefits for mechanical applications – but it can present difficulties when it comes to machining the material. Material profiling of ultra-hard insulators can result in a significant loss to its desirable properties, and commonly depends upon expensive procedures such as diamond grinding. Meanwhile, electrically conductive materials can be efficiently profiled through electro-discharge machining (EDM) with no loss to material hardness.

Weld location pins, or control pins, are hard-wearing and heat-resistant components that are used to precisely locate a material on one or more dimensional planes. Once fixed into position, the material can be accurately welded and, if necessary, moved along pre-determined axes for machining processes with high degrees of precision. This method is primarily used to weld captive nuts to sheet metal or body panels, for manufacturing parts that are used in various automotive and construction sectors.

Sintering is a process by which a powder compact, or ‘green-body’, is transformed into a dense ceramic article which offers the desired characteristics and material properties. The process can enhance the materials mechanical and high-temperature properties, as well as the electrical conductivity, translucency, or thermal conductivity.

Industrial wear applications create exacting conditions for equipment and components due to the inherent abrasiveness, corrosiveness, or high temperature and oxidation resistance damages associated with these specific processes. Sandblasting, for example, is a surface preparation method that blows abrasive grit through shot blast nozzles at high velocities to change the surface texture or roughness of an object. This grit, comprised of tough substances such as cast iron or chill-cast iron, has the capacity to erode the interior components of the abrasive blaster – particularly at the outlet. Shot blast nozzles and their liners must, therefore be composed of high-strength materials capable of withstanding long-term abrasive conditions from high concentrations of small particle erosive elements.

Additive manufacturing (AM), also known as 3D-printing, is the process of designing and manufacturing intricate geometries from a limitless range of materials using innovative deposition techniques. The equipment involved deposits small amounts of a given material into predetermined channels to form small, complex components – as opposed to conventional manufacturing processes which subtract from materials through milling and machining, or pressing and extrusion.
Sialons were developed as a more cost-effective substitute for hot-pressed silicon nitride. They have a complex chemistry and should be considered a family of alloys with a broad range of properties. Sialons are formed when silicon nitride (Si3N4), aluminium oxide (Al2O3) and aluminium nitride (AlN) react. The materials combine to form a wide range of chemical compositions.
International Syalons is one of the UK’s foremost manufacturers and suppliers of high-performance ceramics derived from silicon nitride and sialon ceramics. Our comprehensive guide to the properties and applications of sialon ceramics has recently been published on AZoM, and here is a brief introduction to the extensive article, which can be viewed for free using the link below.

International Syalons have taken delivery and installed a brand new, bespoke and purpose built canteen in order to provide better facilities for our ever growing workforce. The new space which includes improved catering facilities is a much needed addition to the site and as has been welcomed by our highly skilled production staff.
The new building was designed and assembled off site by Portable Building Sales of East Yorkshire, UK and installed extremely quickly and easily.
International Syalons’ sales manager Simon Dodd will be attending Tube 2018 in Dusseldorf on April 18th – 19th.
The trade fair, which takes place every 2 years, attracts more than 31,000 visitors from 134 countries and is the world’s most important fair for tube manufacturing and processing across industries such as automotive, chemical processing, construction, electrical, as well as ferrous and non-ferrous metal forming.
Please feel free to make an appointment with Simon at simon.dodd@syalons.com to discuss your technical or sales needs.
International Syalons are proud to announce that it has successfully been assessed by Lloyds Register of Quality Assurance against the revised international quality standard ISO 9001:2015. This Quality Management System applies to the manufacture of advanced ceramic powders and products.
