Aluminum nitride ceramic sealing ring and preparation method thereof
The invention relates to the technical field of ceramics, in particular to an aluminum nitride ceramic sealing ring and a preparation method thereof.The aluminum nitride ceramic sealing ring is prepared from, by weight, 83-85 parts of aluminum nitride mixed powder and 15-17 parts of binder; the aluminum nitride mixed powder comprises the following materials in parts by weight: 80-85 parts of aluminum nitride powder, 3-7 parts of yttrium oxide and 1-2 parts of a dispersing agent; the binder comprises the following materials in parts by weight: 50-60 parts of paraffin, 3-6 parts of microcrystalline wax, 20-30 parts of high density polyethylene, 8-15 parts of polypropylene and 3-6 parts of stearic acid. The formed green body is high in strength, and the problems of collapse, cracking and the like caused by low strength of the green body can be solved; the sintering deformation is small, the size precision is high, the internal porosity is low, and the product performance is greatly improved; and the mass production efficiency is high.
本发明涉及陶瓷技术领域，具体涉及一种氮化铝陶瓷密封环及其制备方法，氮化铝陶瓷密封环包括以下重量份材料：氮化铝混合粉末83‑85份和粘结剂15‑17份；所述氮化铝混合粉末包括一下重量份材料：氮化铝粉末80‑85份、氧化钇3‑7份和分散剂1‑2份；所述粘结剂包括以下重量份材料：石蜡50‑60份、微晶蜡3‑6份、高密度聚乙烯20‑30份、聚丙烯8‑15份和硬脂酸3‑6份。本发明成型生坯强度高，能解决由于生坯强度低导致的崩缺、开裂等问题；烧结变形小，尺寸精度高，内部气孔率低，大大提高了产品的性能；其大批量生产效率高。
