CERAMIC MATERIAL AND PREPARATION METHOD THEREFOR
The present application provides a ceramic material and a preparation method therefor. The ceramic material comprises: a ceramic principal phase, the ceramic principal phase comprising a solid solution formed by Al2O3-MgO-La2O3; and in the solid solution, the molar ratio of Al2O3, MgO and La2O3 is (20.90-23.10): (2.85-3.15): (1.90-2.10). By means of the described method, the present application can provide a ceramic material having a frequency-temperature coefficient in the range of +-12 ppm/ DEG C.
本申请提供了一种陶瓷材料及其制备方法，该陶瓷材料包括：陶瓷主相，所述陶瓷主相包括Al2O3‑MgO‑La2O3形成的固溶物，其中，所述固溶物中Al2O3、MgO、La2O3的摩尔比为(20.90‑23.10)：(2.85‑3.15)：(1.90‑2.10)。通过上述方式，本申请能够提供一种频率温度系数在±12ppm/℃范围内的陶瓷材料。
