  • In aerospace applications, good resistance and rigidity under high temperatures, as well as low weight and low thermal expansion, are particularly important – all of which are properties found in structural components made of Silicon nitride. This makes the ceramic of interest for, among other things, housings of reconnaissance and observation cameras and for support structures of satellites. The advantage here is that the low thermal expansion, even in the case of extreme temperature fluctuatio Silicon Nitride has the best mechanical, thermal, and electrical properties of any technical ceramic material. Sialon is a silicon nitride ceramic with added a small percentage of aluminum oxide. Sialon is an ideal material for applications where strength at high temperatures, thermal shock resistance, and corrosion resistance are needed. Silicon Nitride’s high flexural strength and excellent fracture toughness make it highly resistant to cracking, breaking, and bending, allowing it to operate u The basis of silicon nitride ceramics is silicon extracted from pure quartz sand (SiO2). Silicon nitride is then usually formed through a reaction of pure silicon with nitrogen at around 1,200 °C / 2,192 °F. Ceramic components made of silicon nitride are then produced using liquid-phase sintering from fine Silicon nitride powder, which is mixed with other sintering additives to enable complete compaction. The compaction and needle-shaped recrystallization of the silicon nitride particles is caus Because of the combination of high strength values, low coefficient of thermal expansion, and a relatively small modulus of elasticity, Si₃N₄ ceramic is particularly suited to thermal shock-stressed cutting tools such as indexable inserts. One application in which this combination of properties has proven particularly useful is machining cast iron materials – such as cast iron or grey cast iron – with high-performance ceramic cutting tools. In contrast to carbide metals or other cutting material The silicon nitride planar waveguide platform has enabled a broad class of low-loss planar-integrated devices and chip-scale solutions that benefit from transparency over a wide wavelength range and fabrication using wafer-scale processes. As a complimentary platform to silicon-on-insulator and III-V photonics, Si 3 N 4 waveguide technology opens up a new generation of system-on-chip applications not achievable with the other platforms alone. The availability of low-loss waveguides ( Silicon nitride offers high wear resistance, strength, rigidity, extremely high abrasion resistance, and good friction characteristics combined with high resistance to temperature and corrosion, making it ideal as a ceramic roller bearing material for hybrid roller bearings. Si₃N₄ components have good dry-running properties in hybrid storage applications and are often used in low-maintenance and maintenance-free assemblies.
