Description
Product Overview
The SINM Si3N4 silicon nitride ceramic sheet is engineered for applications that demand the highest levels of hardness, thermal stability, and dimensional precision. Manufactured using advanced hot‑pressed technology, the sheet achieves a uniform thickness of 0.32 mm while retaining the intrinsic strength of silicon nitride. Its composition provides excellent resistance to oxidation, chemical corrosion, and thermal shock, allowing it to operate continuously at temperatures up to 1200 °C without degradation. The sheet dimensions of 50 × 50 mm make it a versatile substrate for a wide range of industrial and scientific uses, from high‑frequency electronic components to specialized thermal management systems. The material’s low thermal conductivity combined with high dielectric strength makes it an outstanding insulating medium, while its high Young’s modulus ensures mechanical rigidity in demanding environments.
Usage
Designed for engineers, researchers, and manufacturers, this silicon nitride sheet excels in high‑temperature electronics, aerospace components, and advanced sensor platforms. It can be employed as a substrate for power semiconductor devices, where its ability to dissipate heat while insulating electrically is critical. In aerospace, the sheet serves as a thermal barrier in engine components and as a structural element in lightweight composite assemblies. Laboratory settings benefit from its chemical inertness, using the sheet as a holder for corrosive reagents or as a component in high‑temperature furnaces. Its compact size also enables integration into miniature devices, such as MEMS (Micro‑Electro‑Mechanical Systems) where space constraints demand ultra‑thin yet robust materials.
