The invention discloses a composite boron nitride ceramic high-temperature nozzle and a preparation method thereof. The composite boron nitride ceramic high-temperature nozzle is prepared from the following raw materials in parts by mass: 60-70 parts of boron nitride, 10-15 parts of silicon carbide, 30-40 parts of zirconium dioxide, 10-16 parts of silicon dioxide, 10-15 parts of silicon nitride, 2-6 parts of a binding agent, 2-6 parts of lead oxide, 3-5 parts of feldspar, 3-5 parts of continuous carbon fibers, 2-6 parts of a stabilizer, 3-6 parts of an auxiliary agent and a proper amount of water. Beneficial effects are as follows: the defects of a single material are overcome; besides, the two parts are combined to form a complete nozzle, an assistant is added into one part to further improve the thermal shock resistance, and the part with better thermal shock resistance is used at one end close to the high-temperature device body, so that the high-temperature nozzle can tolerate a high-temperature environment better, and unnecessary material waste is reduced while the actual use environment is met.
本发明公开了一种复合氮化硼陶瓷高温喷嘴及其制备方法，该复合氮化硼陶瓷高温喷嘴由以下质量份数的原料制成：氮化硼60‑70份、碳化硅10‑15份、二氧化锆30‑40份、二氧化硅10‑16份、氮化硅10‑15份、结合剂2‑6份、氧化铅2‑6份、长石3‑5份、连续碳纤维3‑5份、稳定剂2‑6份、助剂3‑6份和适量水。有益效果：改善了单一材质所具有的弊端，此外，通过两个部件的组合构成一个完整喷嘴，在其中一个部件中加入助剂进一步提高耐热冲击性，在靠近高温器体的一端使用耐热冲击性更好的部件，更能耐受高温环境，使其满足实际使用环境的同时也减少了不必要材料的浪费。
