Nitride ceramic microsphere and preparation method thereof
The invention discloses nitride ceramic microspheres and a preparation method thereof.The preparation method of the nitride ceramic microspheres comprises the following steps that a nitrogen-based emulsifier solution is prepared, the nitrogen-based emulsifier solution comprises a solvent and an emulsifier, the solvent is water, and the ratio of the water to the emulsifier is (55-75): (0.3-0.45); preparing a nitride ceramic microsphere precursor solution; separating powder in the nitride ceramic microsphere precursor solution from a solvent to obtain a paste material; and washing the paste material, and calcining in a nitrogen or inert gas atmosphere to obtain the nitride ceramic microspheres, the calcining temperature is 1300 to 1600 DEG C; the prepared nitride ceramic microspheres are small in particle size, a large amount of organic solvent does not need to be adopted in the preparation process, and preparation is carried out under normal pressure.
本发明公开了一种氮化物陶瓷微球及其制备方法，所述氮化物陶瓷微球制备方法包括以下步骤：制备氮基乳化剂溶液，所述氮基乳化剂溶液包括溶剂、乳化剂，所述溶剂为水，水、乳化剂的比例为(55‑75)：(0.3‑0.45)；制备氮化物陶瓷微球前驱体溶液；将所述氮化物陶瓷微球前驱体溶液中的粉末与溶剂分离，得到膏状物料；将所述膏状物料洗涤后，在氮气或惰性气体气氛下煅烧得到所述氮化物陶瓷微球；煅烧温度为1300‑1600℃；实现了制备的氮化物陶瓷微球粒径小，且制备过程中不需要采用大量的有机溶剂，且在常压下制备。
