Specifications of High Polished Si3n4 Silicon Nitride Ceramic Bar and Parts

High-polished Si3N4 silicon nitride ceramic bars and components are crafted for demanding commercial applications. The product composition is silicon nitride (Si3N4), an advanced ceramic recognized for high toughness, thermal resistance, and chemical stability. These elements are sintered at severe temperatures to attain complete thickness, making sure minimal porosity and maximum toughness. The end products undergo precision grinding and brightening to achieve a surface area roughness below Ra 0.2 micrometers, ideal for friction-sensitive atmospheres.

Requirement diameters for ceramic bars range from 3 mm to 50 mm, with sizes approximately 500 mm. Customized dimensions are offered. The density of silicon nitride parts is 3.2-3.3 g/cm ³, lighter than steel however with premium hardness (Hv 1500-1700). Operating temperature level restrictions extend from -196 ° C to 1200 ° C, making them perfect for severe thermal biking. Thermal conductivity is low (15-20 W/m · K), decreasing warmth transfer in high-temperature arrangements. The coefficient of thermal growth is 3.2 x 10 ^ -6/ ° C, decreasing dimensional modifications under warm tension.

Mechanical properties consist of a flexural toughness of 600-800 MPa and a crack sturdiness of 6-7 MPa · m ONE/ ², outmatching many steels and porcelains. Electric insulation is kept approximately 1000 ° C, protecting against existing leak in digital or high-voltage systems. Chemical inertness allows resistance to acids, antacid, and molten metals, making certain longevity in corrosive setups.

Applications span aerospace, automotive, semiconductor production, and medical gadgets. Usual uses include bearings, cutting tools, welding pins, and insulating parts. The polished surface minimizes wear in moving components, prolonging service life. All components satisfy ISO 9001 and RoHS standards, guaranteeing quality and ecological compliance.

Custom-made shapes, holes, threads, and finishings (like anti-static layers) are offered. Technical illustrations or samples can be sent for tailored options. Preparations vary by intricacy, with standard products delivered within 2-3 weeks. Product packaging utilizes anti-impact materials to avoid damage throughout transit.
