silicon-nitride ceramic

...Silicon nitride magnetic rings are mainly used to protect high voltage electrodes and are widely used in the photovoltaic industry.Heat shields and magnetic rings, as well as ceramic rings, are collectively referred to as electrode shields.Silicon nitride electrode protection cover mainly uses silicon nitride insulation, heat resistance and corrosion resistance.Compared with the protective cover...

... – industrial ceramics are finding new applications all the time. For over 20 years, we have been practicing the cutting and drilling of ceramic materials, such as AL2O3, silicon nitride, or zirconium oxide, using lasers. We are capable of processing material thicknesses from 0.1 mm to 27 mm. Currently, we operate five systems dedicated exclusively to ceramic processing. Our workstations are soundproofed, climate-controlled, and equipped with modern extraction systems.

...applications. Due to its specific properties, silicon nitride is lightweight, ultra-robust, and highly wear-resistant. These premium, high-quality bearings are used, for example, in the aerospace and space sectors, in the metallurgical industry (high operating temperatures), in machine construction, in the chemical industry (chemically aggressive environments), in the pharmaceutical industry, in...

...The balls of the HQW bearings are made of stainless steel (X65Cr13) as standard. However, for particularly demanding applications, ceramic balls made of silicon nitride or zirconium oxide are used. For the spindle ball bearings from HQW, only balls from accuracy classes Grade 3 and 5 are used. These two classes meet the highest tolerances regarding dimensions, roundness, and roughness.

... bearings are manufactured exclusively through subtractive processes. In contrast to the mass production of injection-molded plastic bearings, this manufacturing method guarantees high quality, dimensional accuracy, and long durability. The following materials are typically used for the production of plastic ball bearings: Outer and inner rings: POM • PE • PPH • PETP • PTFE • PA • PEEK • PVDF • PSU Balls: Soda-lime glass • Duranglass • Stainless steel 1.4401 • Stainless steel 1.4571 • POM • PP • PVC • PEEK • Ceramic • PVDF Ball bearings made entirely of PEEK are also available.

...Ceramic nozzles made from materials such as silicon carbide, aluminum oxide, zirconium oxide, and silicon nitride are just one example of a meaningful application with high economic value. The excellent properties of ceramics against sliding, impact, or abrasive wear, as well as their resistance to chemical attack from aggressive media, are particularly advantageous for nozzle components. Similarly, ceramic nozzles made from silicon nitride reliably perform their function even at high temperatures, ensuring a longer service life compared to carbide components.

... silicon nitride exhibit very high mechanical strength and fracture toughness. The welding rollers are produced from silicon nitride or aluminum oxide. Both materials demonstrate very high wear resistance, with silicon nitride outperforming Al2O3 due to its exceptional thermal shock resistance. Ceramic pads for single-sided welding are available as unassembled ceramic profiles profiles glued onto self-adhesive aluminum foil strung onto wire.

...Silicon Nitride (Si3N4), just like its close family relation silicon carbide, is one of the toughest technical ceramics available. Over the years it has been successfully used in a wide and interesting field of applications ranging from automotive engine components to roller bearings for the most exclusive skateboards (right).

...For full ceramic bearings or hybrid bearings, hot isostatically pressed silicon nitride (HIPSN) is generally used, at least for the rolling elements.

...The choice of a ceramic substrate for PCB design is becoming increasingly popular. The high maximum operating temperatures of 800°C+ allow for much higher operating temperatures at which silicon carbide and gallium nitride semiconductors can now operate. The new DPC (Direct Plated Copper) manufacturing method also enables miniaturization and microelectronics that are not possible with other methods. Ceramics are resistant to UV rays, and their inert nature makes these substrates ideal even when a hermetic package is required, where outgassing or humidity cannot be tolerated.

...Ceramic rods: We manufacture your parts according to specifications and technical drawings for all types of ceramics such as aluminum oxide, zirconium oxide, silicon carbide, and silicon nitride.

... application. They are available with full balls or with cages made of PEEK or PTFE. The runout accuracies common with precision steel bearings cannot be achieved with all-ceramic bearings, so speed values have to be reduced. Ceramic materials are harder than steel, but also more brittle. Silicon nitride in particular has a low elongation at break and tends to break under tensile stress without prior plastic deformation. We take this into account when selecting the optimum bearing solution for your specific requirements.

...Silicon nitride is one of the hardest ceramics but also one of the most resistant. Si3N4 is mainly used in severe environments which combine extreme temperatures with abrasive and/or corrosive medium. Silicon nitride can be of different grades : sintered, hot pressed or reaction bonded. Selection of materials Microcertec offers two high-purity Si3N4 grades that are particularly suited for...

...) and the rolling elements are made of silicon nitride ceramic (Si3N4). Hardened rolling bearing steel is paired with high-performance ceramic. Ceramic proves to be stronger and much more durable than, for example, steel. Hybrid ball bearings thus represent the future for electric motor manufacturers, as the demand for stronger, more durable, and longer-lasting bearings is increasing. The hybrid deep groove ball bearing is the most common design, but they are available in a wide variety of versions and designs.
