Aluminum nitride ceramic and preparation method thereof
The invention relates to the field of ceramic materials, in particular to aluminum nitride ceramic and a preparation method thereof. The preparation method of the aluminum nitride ceramic comprises the following steps: mixing aluminum nitride powder with a sintering aid to obtain mixed powder, and carrying out compression molding on the mixed powder to obtain an aluminum nitride ceramic green body; the carbon content of the aluminum nitride powder ranges from 0.05 wt% to 0.1 wt%, and the oxygen content of the aluminum nitride powder ranges from 0.6 wt% to 1.2 wt%; and sintering the aluminum nitride ceramic green body to obtain the aluminum nitride ceramic. The preparation method of the aluminum nitride ceramic provided by the invention can reduce the preparation cost of the aluminum nitride ceramic.
本公开涉及陶瓷材料领域，具体涉及一种氮化铝陶瓷及其制备方法。该氮化铝陶瓷制备方法包括：将氮化铝粉体与烧结助剂混合得到混合粉料，并对所述混合粉料进行压制成型，得到氮化铝陶瓷生坯；所述氮化铝粉体的含碳量为0.05~0.1wt%，含氧量为0.6~1.2wt%；对所述氮化铝陶瓷生坯进行烧结，得到氮化铝陶瓷。本公开提供的氮化铝陶瓷制备方法能够降低氮化铝陶瓷制备的制备成本。
