Specifications of Si3N4 Silicon Nitride Ceramic Plates/Substrates/Sheets

Si3N4 silicon nitride ceramic plates/substrates/sheets are high-performance technical ceramics developed for requiring commercial applications. The material composition is silicon nitride (Si3N4), a substance understood for outstanding thermal, mechanical, and electric properties. These ceramic products operate dependably in severe settings due to their high-temperature stability, maintaining structural honesty as much as 1000 ° C in oxidizing environments and higher in inert conditions.

The mechanical strength of silicon nitride ceramics transcends to several other innovative porcelains. They exhibit high crack sturdiness (6-7 MPa · m ¹/ TWO) and flexing stamina (700-1000 MPa), standing up to split proliferation under stress and anxiety. This makes them optimal for load-bearing components. The solidity varies in between 14-16 Grade point average (Vickers), guaranteeing outstanding wear resistance in unpleasant setups.

Thermally, Si3N4 porcelains have reduced thermal expansion (3.2 × 10 ⁻⁶/ ° C), decreasing dimensional modifications during rapid temperature level changes. Their thermal conductivity (15-30 W/m · K) sustains effective warmth dissipation, appropriate for thermal monitoring applications. Electrical insulation buildings continue to be secure at high temperatures, with volume resistivity surpassing 10 ¹⁴ Ω · cm at 500 ° C, avoiding present leak in high-voltage settings.

Chemical resistance is an additional crucial benefit. Silicon nitride stands up to corrosion from a lot of acids, antacid, and molten steels, ensuring sturdiness in chemically aggressive setups. Surface area coating options consist of brightened (Ra ≤ 0.1 μm) or as-sintered surface areas, customized for details friction or sealing needs.

Requirement thickness ranges from 0.2 mm to 20 mm, with measurements up to 200 mm × 200 mm offered. Personalized shapes and sizes are producible by means of precision machining, consisting of laser cutting or grinding. Applications cover aerospace (engine elements), vehicle (turbocharger blades), electronics (semiconductor substrates), and industrial machinery (bearing spheres, cutting tools).

Qualities differ for specific needs– high-purity qualities for semiconductor equipment, high-toughness qualities for mechanical components. Optional metallization (e.g., tungsten, molybdenum-manganese) allows brazing or soldering to metals. Testing certifications (ISO 9001, RoHS) make certain quality compliance. Product packaging uses anti-static products to avoid contamination during handling.
