Aluminum titanate reinforced periclase complex-phase ceramic material
The invention relates to an aluminum titanate reinforced periclase complex-phase ceramic material, which is characterized by being prepared by the following steps: putting magnesium oxide powder and aluminum titanate powder into a ball mill for wet milling to obtain mixed slurry; drying and screening the mixed slurry to obtain fine ceramic powder; carrying out dry pressing molding on the fine ceramic powder to obtain a complex-phase ceramic green body; and sintering the complex-phase ceramic green body in a high-temperature furnace to obtain the periclase complex-phase ceramic material. According to the method, the characteristics of low expansion coefficient and good high-temperature performance of aluminum titanate are effectively utilized, the thermal expansion coefficient of the periclase complex-phase ceramic material is reduced, and the sintering performance and thermal shock resistance of the periclase complex-phase ceramic material are improved.
本发明涉及一种钛酸铝增强方镁石复相陶瓷材料，其特征在于：将氧化镁粉体和钛酸铝粉体放于球磨机湿磨，得到混合浆料；将混合浆料经干燥和筛分后，得到精细陶瓷粉；将精细陶瓷粉干压成型，得到复相陶瓷坯体；将复相陶瓷坯体置于高温炉中烧结，得到方镁石复相陶瓷材料。本发明方法有效利用钛酸铝膨胀系数低和高温性能好的特点，降低方镁石复相陶瓷材料的热膨胀系数，提高方镁石复相陶瓷材料的烧结性能和抗热震性能。
