Heterogeneous composite boron nitride
The hot pressed composite boron nitride ceramic products produced by Zhuoyu Technology adopt international advanced vacuum hot pressing sintering technology, relying on industry advanced technical support and unique material ratios to ensure that the materials have good thermal conductivity, high thermal shock resistance, erosion resistance and other properties, suitable for a series of high-performance industrial applications.
High thermal conductivity, compressed into various forms, used as high-temperature, high-pressure, insulation, and heat dissipation components, such as nozzles for aircraft and rocket engines.
Excellent thermal shock resistance and erosion resistance, applied to amorphous ribbons and nozzles, 3D printed metal powder guide tubes, nozzles and other high-strength non adhesive materials, suitable for various hot pressing molds.
• Boron nitride horizontal continuous casting separation ring;
• Boron nitride thin strip continuous casting side sealing plate;
• Amorphous and nanocrystalline boron nitride nozzles;
• Special metal powder nozzles and guide pipes;
Zhuoyu can customize various anisotropic composite boron nitride products according to customer drawings and requirements.
