Key market applications:High temperature furnace insulation parts, thermocouple protection tubeAmorphous nozzle and powder metal atomizing nozzleHigh temperature mechanical components, such as bearings, valves and gaskets, etc.Molten metal crucible or moldHorizontal continuous casting separation ringMuffle kiln and crucible for nitride and Sialon firingP-type diffusion source in the semiconductor industryMOCVD regulator and its partsCasting and rolling partsMachinable ceramics and excellent machining performanceProduct processing recommendations:Boron nitride ceramic materials have excellent machining properties and can be processed into complex shapes with very small tolerances as required. The following matters should be paid attention to in the processing of boron nitride ceramic materials:Boron nitride ceramic materials can be processed with standard high-speed steel cutting tools. For the processing of harder PBN-E and composite materials, cemented carbide tools or diamond tools are recommended.Grinding can be carried out as required, and standard taps and dies can be used to machine threads.The machining process should always be kept dry, without the use of cutting oil and coolant.Cutting tools should be sharp and clean, and do not use cutting tools with negative inclination.When processing materials, be careful when jamming and clamping to avoid excessive pressure. Down-milling technology should be used to prevent missing edges and corners.
