Specifications of Low Thermal Conductive Silicon Nitride Si3N4 Ceramic Tube/Rod

Reduced Thermal Conductive Silicon Nitride (Si3N4) Ceramic Tubes/Rods are engineered for high-performance applications calling for marginal warmth transfer combined with exceptional toughness. The material’s thermal conductivity is dramatically reduced, usually ranging between 15-20 W/m · K. This building makes it suitable for environments where heat retention or insulation is critical. The ceramic structure ensures security under extreme temperature levels, keeping stability in problems as much as 1200 ° C in air. In inert ambiences, it withstands also greater temperature levels without breaking down.

The mechanical stamina of Si3N4 ceramics is superior. Flexural stamina surpasses 800 MPa, making sure resistance to flexing or fracturing under heavy tons. Crack toughness values reach approximately 6-7 MPa · m ¹/ ², minimizing the threat of cracks circulating via the material. This strength is coupled with high hardness (around 1500 HV), providing wear resistance in unpleasant settings.

Chemical resistance is an additional crucial attribute. Silicon nitride withstands corrosion from acids, alkalis, and molten metals. This makes it suitable for usage in aggressive industrial atmospheres like chemical handling or metal casting. Electric insulation residential properties stay stable at raised temperature levels, protecting against existing leak in high-voltage or high-temperature applications.

Dimensional accuracy is focused on. Tubes and rods are made with tight tolerances, guaranteeing uniformity in inner/outer diameters and wall densities. Surface area finishes are smooth, lessening rubbing and use in dynamic applications. Standard dimensions for tubes consist of sizes as much as 500 mm, outer diameters from 5-100 mm, and wall surface densities from 1-10 mm. Poles are offered in sizes ranging from 3-50 mm, with personalized measurements possible based upon requirements.

Applications extend aerospace, metallurgy, power, and semiconductor markets. Common uses consist of thermocouple protection sheaths, heater parts, welding nozzles, and insulators. In semiconductor manufacturing, the material’s pureness and thermal stability protect against contamination during high-temperature procedures.

Reduced thermal conductive Si3N4 ceramic tubes/rods use integrity sought after setups. The combination of thermal insulation, mechanical toughness, and chemical inertness ensures long life span. Personalization options for geometry, surface treatment, and material structure enable adaptation to certain functional requirements.
