Aluminum oxide powder, aluminum oxide ceramic and preparation method of aluminum oxide ceramic
The invention relates to aluminum oxide powder, and an aluminum oxide ceramic and a preparation method thereof, and provides aluminum oxide ceramic powder, which comprises the following components inparts by weight: 100-115 parts of aluminum oxide, 23-28 parts of aluminum hydroxide, 5-6 parts of magnesium oxide, 6-7 parts of titanium dioxide powder, 1-5 parts of magnesium silicon nitride powder,10-15 parts of a silane coupling agent, 3-4 parts of a binder, 15-20 parts of zirconium oxide, 2-6 parts of aluminum nitride powder, 1-2 parts of a defoaming agent and 5-8 parts of AlF3. According tothe invention, the raw material components of the aluminum oxide ceramic are reasonably matched, so that the use quality of the aluminum oxide ceramic powder is optimized; and the green body is kept in a certain shape and has high density and compactness by virtue of the interaction force among aluminum nitride, aluminum oxide, zirconium oxide and magnesium oxide, so that ceramic sintering is facilitated, the sintering temperature can be reduced, and the ceramic density is improved.
本发明为一种氧化铝粉体、氧化铝陶瓷及其制备方法，提出了一种氧化铝陶瓷粉料，按照重量分数包括如下组分：氧化铝100‑115份，氢氧化铝23‑28份、氧化镁5‑6份、二氧化钛粉6‑7份、镁氮化硅粉1‑5份和硅烷偶联剂10‑15份，粘结剂3‑4份、氧化锆15‑20份、氮化铝粉2‑6份、消泡剂1‑2份和AlF35‑8份。本发明得到的氧化铝陶瓷原料组分进行了合理的配伍，从而优化了氧化铝陶瓷粉料的使用品质。本发明依靠氮化铝、氧化铝、氧化锆和氧化镁之间的相互作用力使坯体保持一定的形状和致密度高致密坯体，其有利于陶瓷烧结，可以降低烧结温度，提高陶瓷致密度。
