5 FAQs of factory ceramic use nano Si3N4 Silicon Nitride powder

What is nano Si3N4 Silicon Nitride powder? Nano Si3N4 Silicon Nitride powder is a high-performance ceramic material composed of silicon and nitrogen atoms arranged in a crystalline structure. It is engineered at the nanoscale (particle sizes typically between 20-100 nanometers) to enhance properties like thermal shock resistance, mechanical strength, and chemical stability. This ultrafine powder is synthesized through processes like carbothermal reduction or chemical vapor deposition, ensuring purity and uniform particle distribution for industrial applications.

Why is nano Si3N4 used in ceramics? Nano Si3N4 is prized in advanced ceramics for its exceptional thermal stability (withstanding temperatures up to 1,800°C in inert environments), low thermal expansion, and high fracture toughness. Its nano-sized particles improve sintering efficiency, enabling denser, stronger ceramic components with superior wear resistance. This makes it ideal for high-stress applications like cutting tools, bearings, and engine parts, where traditional ceramics may fail under extreme heat or mechanical load.

What industries use Si3N4 ceramic components? Industries such as aerospace, automotive, energy, and electronics rely on Si3N4 ceramics. Examples include turbine blades, glow plugs, semiconductor manufacturing equipment, and medical implants. Its electrical insulation properties and resistance to corrosion also make it suitable for harsh environments, such as in chemical processing or high-voltage systems.

Is nano Si3N4 powder safe to handle? While non-toxic, nano Si3N4 powder requires careful handling to avoid inhalation or skin contact. Dust particles can irritate respiratory systems, so use PPE (masks, gloves) and work in well-ventilated areas. Follow OSHA or local safety guidelines for nanomaterials. Once sintered into solid ceramics, the material poses minimal risk and is biocompatible for medical uses.

How should nano Si3N4 powder be stored? Store in airtight, moisture-proof containers away from humidity and direct sunlight. Exposure to air can cause oxidation or clumping. Ideal storage temperatures range between 15-25°C. Avoid contamination by metals or organic materials, which can degrade performance during high-temperature processing. Shelf life is typically 12-24 months if stored correctly.
