Specifications of BN+Si3N4 composite ceramic/boron nitride add silicon nitride composite ceramic

The BN+S i3N4 composite ceramic combines boron nitride (BN) with silicon nitride (Si3N4) to develop a high-performance product fit for demanding industrial applications. This composite merges the unique properties of both components. Boron nitride adds superb thermal security and lubricity. Silicon nitride includes high mechanical strength and fracture durability. The result is a ceramic material that stabilizes warmth resistance, put on resistance, and structural dependability.

The material operates efficiently in temperatures approximately 1800 ° C in inert environments. It preserves stability in oxidizing environments up to 1200 ° C. Its reduced thermal development coefficient minimizes dimensional changes under rapid heating or cooling. This makes it ideal for components exposed to thermal biking, like furnace parts or aerospace heat shields.

Mechanical homes consist of a hardness variety of 12-15 Grade point average. The flexural stamina normally drops between 500-700 MPa. These worths ensure resistance to cracking under high-stress conditions. The composite’s crack strength reaches 6-8 MPa · m ONE/ TWO, outperforming several traditional porcelains. This strength lowers the risk of unexpected failing in load-bearing applications.

Electrical insulation stays solid even at heats. The dielectric toughness goes beyond 15 kV/mm. This fits the product for use in electronic substratums or insulators within high-voltage systems. Its non-reactive nature enables compatibility with liquified steels, acids, and antacid. This corrosion resistance extends service life in rough chemical environments.

The composite’s reduced density (2.8-3.2 g/cm ³) sustains light-weight layouts without compromising toughness. It is machinable in pre-sintered states, making it possible for accurate shaping for complicated geometries. Usual applications include cutting devices, bearing parts, and semiconductor handling tools.

Thermal conductivity varieties from 25-35 W/m · K. This assists in reliable heat dissipation in thermal administration systems. The material’s self-lubricating buildings decrease friction in moving parts, decreasing energy usage.

Production uses warm pressing or stimulate plasma sintering to accomplish thick, uniform microstructures. Customized formulations change the BN-to-Si3N4 ratio to focus on specific characteristics like thermal conductivity or mechanical solidity. This adaptability allows tailored services for sectors like energy, vehicle, and progressed production.
