Boron nitride composite ceramic as well as preparation method and application thereof
The invention provides boron nitride composite ceramic as well as a preparation method and application thereof, and belongs to the technical field of ceramic nozzles. The boron nitride composite ceramic provided by the invention comprises the following preparation raw materials in parts by weight: 60-70 parts of boron nitride, 10-20 parts of an inorganic binder, 3-10 parts of a modifier and 10-20parts of zirconium oxide. On the basis of the pure-phase boron nitride ceramic, the inorganic binder, the modifier and the zirconium oxide are added, so that the excellent machining performance of thepure-phase boron nitride is inherited, and the mechanical property and the metal erosion resistance are greatly improved. According to the embodiment, the density of the boron nitride composite ceramic provided by the invention can reach 96% or above; and meanwhile, the boron nitride composite ceramic has excellent mechanical properties, thermal shock resistance and metal erosion resistance, andwhen the the boron nitride composite ceramic is used for a ceramic nozzle, the thermal shock resistance and the metal erosion resistance of the ceramic nozzle can be improved, the nozzle blockage phenomenon is reduced, and the service life of the nozzle is prolonged.
本发明提供了一种氮化硼复合陶瓷及其制备方法和应用，属于陶瓷喷嘴技术领域。本发明提供的氮化硼复合陶瓷包括以下重量份数的制备原料：氮化硼60～70份，无机粘结剂10～20份，改性剂3～10份，氧化锆10～20份。本发明在纯相氮化硼陶瓷基础上，添加无机粘结剂、改性剂和氧化锆，不仅继承了纯相氮化硼优异的机械加工性能，还大大提高了力学性能以及抗金属冲蚀能力。根据实施例可知，本发明提供的氮化硼复合陶瓷的致密度可达96％以上；同时具有优异的力学性能、抗热震性以及抗金属冲蚀能力，将其用于陶瓷喷嘴，能够提高陶瓷喷嘴的抗热震性以及抗金属的冲刷能力，减少喷嘴堵包现象，延长其使用寿命。
