Silicon Nitride Nozzles: Blasting, Extrusion & Flow Applications

Silicon nitride (Si3N4) ceramics offer some of the best-in-class tribological properties, with outstanding nominal fracture toughness (Syalon 101 = 7.7 MPa m1/2) and exceptional strength characteristics (compressive, flexural, etc.). This combination makes silicon nitride ideal for precise wear applications where components are subjected to significant ongoing stress throughout service: dies, weld rolls, and cutting tools for example.Continue reading

How Advances in Technical Ceramics Aid Industry 4.0

Humanity’s technical achievements have been founded on the ability to reinvent and revolutionise existing innovations. At one point in history, the use of draft animals was the height of labour efficiency. This was surpassed by the genesis of steam power which liberated manufacturers and ushered in a new age of mechanization. Gas, oil, and electricity eventually surpassed steam, and nuclear power ultimately overtook those. Each of these innovations was so profound that they have come to define three distinct eras based on their industrial capacities; also known as the first three industrial revolutions.Continue reading

Sialons for Oil and Gas Industry

Comparing Technical Ceramics: Sialon vs Zirconia

Technical ceramics like sialons and zirconia are among the most advanced materials ever engineered by mankind, enabling new application areas that were practically impossible before their commercial realisation. With many technical ceramics, there is a substantial overlap between their thermomechanical and chemical properties, which can complicate ideal material selection for distinct applications. In the case of sialons and zirconia however, the materials can be easily and respectively distinguished as a non-oxide and an oxide ceramic.Continue reading

Technical Ceramics: Building the Internet of Things

The Internet of Things (IoT) refers to a growing system of interconnectivity between devices and machinery – even those not typically associated with digital communications. Domestic markets have felt the impact of IoT devices most keenly, with the onset of intelligent virtual assistants (IVAs), smart energy monitoring, and WIFI-enabled appliances. Analysts predict that 26 – 100 billion IoT-enabled devices will be in service worldwide by 2020, a growing portion of which will rely on technical ceramics to function correctly. However, these estimates fail to reconcile the comparatively slow uptake of connected devices in industrial settings.Continue reading

Advanced Ceramic Materials: Fundamental to the Future of AI?

The U.S. National Academy of Engineering (NAE) highlighted reverse-engineering of the human brain as one of the world’s greatest research challenges in the 21st Century. It was established as a priority alongside the economization of solar power and the realization of fusion on earth. By incorporating the aim of breaking down human cognitive abilities and building systems that can replicate them onto this list, the NAE essentially brought the field of artificial intelligence (AI) and machine learning out of an exclusively digital space and into the remit of materials science. Advanced ceramic materials, alloys, composites, polymers, and more, are now at the forefront of AI research efforts.Continue reading

Weld Rolls

Benefits of Silicon Nitride Welding & Forming Rollers

Seam welding is one of the most common processes used to join the faying surfaces of unfinished cylindrical profiles (pipes, tubes, etc.). It exploits a similar principle to standard spot welding to produce a durable, longitudinal weld along the full length of the tubular workpiece. The process is typically automated to ensure a uniform solid-state bond, while precision is guaranteed due to the use of welding and forming rollers.Continue reading

Silicon Nitride for Pump Components: Properties & Benefits

Pumping technologies are fundamental to success in an array of market sectors, from municipal water supplies to proprietary ultra-high vacuum (UHV) processing. Poor performance or malfunction in such applications can be extremely costly. Water loss due to leaks in pipelines is estimated to cost billions in annual revenue while inefficient vacuum leak rates in UHV processing can render experiment/production parameters void. These concerns are further amplified when pumps are required to operate in extreme conditions, which can cause conventional pump materials to deteriorate and fail.Continue reading
