Hydrolysis-resistant aluminum nitride powder and preparation method thereof
The invention particularly relates to anti-hydrolysis aluminum nitride powder and a preparation method thereof, and belongs to the technical field of inorganic nonmetallic materials, the method comprises the following steps: dissolving organic acid and a modifier in a solvent to obtain a mixed solution; mixing aluminum nitride powder with the mixed solution, and then dispersing to obtain slurry; performing solid-liquid separation and drying on the slurry to obtain hydrolysis-resistant aluminum nitride powder; according to the method, after organic acid is dispersed in ethyl alcohol, a nonionic modifier is added to treat AlN powder, a protective shell is formed outside the AlN powder, the aluminum nitride powder prepared through the method can not be hydrolyzed after being soaked in water at the room temperature for 16 d, and the modified aluminum nitride powder can stably exist in water for 120 h at the temperature of 60 DEG C and cannot be hydrolyzed.
本发明特别涉及一种抗水解氮化铝粉末及其制备方法，属于无机非金属材料技术领域，方法包括：将有机酸和改性剂溶解于溶剂中，得到混合溶液；将氮化铝粉末和所述混合溶液混合，后进行分散，得到浆料；将所述浆料进行固液分离和烘干，得到抗水解氮化铝粉末；通过使用有机酸在乙醇中分散后，加入非离子型改性剂对AlN粉末进行处理，在AlN粉末外部形成保护壳体，本方法制备的氮化铝粉末在室温下浸泡在水中可以16d不水解，在60℃条件下，改性后的氮化铝粉末在水中可以稳定存在120h不发生水解。
