Aluminum nitride powder as well as preparation method and application thereof
The invention discloses aluminum nitride powder as well as a preparation method and application thereof. The preparation method of the aluminum nitride powder is characterized in that the method comprises the following steps: enabling an aluminum source, activated carbon and a pore-foaming agent to be subjected to a hydrothermal reaction and obtaining a solid precursor is obtained, wherein the aluminum source is aluminum salt, and the pore-foaming agent is water-soluble hydroxide; and calcining the solid precursor and a nitrogen source to obtain the aluminum nitride powder. The activated carbon is used as a carbon source reducing agent, the pore-foaming agent is utilized to form a nano structure, the nano activated carbon structure not only can be used as a template for growth of nano aluminum nitride, but also can enable the aluminum element and the activated carbon to be mixed more uniformly, and the obtained aluminum nitride powder is higher in purity.
本发明公开了一种氮化铝粉体及其制备方法与应用。本发明氮化铝粉体的制备方法，其特征在于，包括以下步骤：将铝源、活性炭和致孔剂进行水热反应，得到固体前驱体，其中，铝源为铝盐，致孔剂为水溶性氢氧化物；再将固体前驱体和氮源进行煅烧，得到氮化铝粉体。本发明以活性炭作为碳源还原剂，利用致孔剂使其形成纳米结构，该纳米活性炭结构不仅能作为纳米氮化铝生长的模板，还能使铝元素与活性炭的混合更加均匀，所得氮化铝粉体纯度更高。
