Ceramic composite and preparation method thereof
Ceramic composites and methods of making the same are provided. The preparation method of the ceramic compound comprises the following steps: mixing aluminum slag and a carbon accelerant to obtain a mixture; and reacting the mixture in a nitrogen atmosphere and at a temperature equal to or greater than 1600 DEG C to obtain the ceramic composite. Wherein the aluminum slag comprises aluminum, oxygen, nitrogen and magnesium. The weight ratio of oxygen to aluminum is 0.6-2. The weight ratio of nitrogen to aluminum is 0.1-1.2. The weight ratio of magnesium to aluminum is 0.04 to 0.2. Wherein the ceramic composite comprises aluminum nitride accounting for at least 90 wt% of the ceramic composite.
提供陶瓷复合物及其制备方法。陶瓷复合物的制备方法包括：混合铝渣及碳促进剂，以获得混合物；以及使混合物在氮气环境中且在等于或大于1600℃的温度下进行反应，以获得陶瓷复合物。其中，铝渣包括铝、氧、氮及镁。氧与铝的重量比值为0.6～2。氮与铝的重量比值为0.1～1.2。镁与铝的重量比值为0.04～0.2。其中，陶瓷复合物包括占陶瓷复合物的至少90wt％的氮化铝。
