在进行干式混合时，将例如氧化铝源、氧化镁源及氧化钛源混合即可，由可制备出具有均匀组成的钛酸铝镁-氧化铝复合陶瓷的观点出发，优选通过在粉碎容器内与粉碎介质一起搅拌，边粉碎边混合。使用二氧化硅源时，将氧化铝源、氧化镁源及氧化钛源与二氧化硅源一起在粉碎容器内搅拌即可。

粉碎通过例如在粉末容器内投入原料及粉碎介质后，使粉碎容器振动或者旋转来进行。通过使粉碎容器振动或者旋转，原料粉末与粉碎介质一起被搅拌并混合，同时被粉碎。为了使粉碎容器振动或旋转，可以使用例如振动磨、球磨机、行星磨、高速旋转粉碎机等销棒粉碎机等惯用的粉碎机，从工业性规模上易于实施的角度出发，优选使用振动磨。在使粉碎容器振动时，其振幅通常为2mm-20mm，优选为12mm以下。粉碎可以连续式进行，也可以间歇式进行，但是从工业性规模上易于实施的角度看，优选连续式进行。

通过烧结这样的混合物，能够得到本发明的钛酸铝镁-氧化铝复合陶瓷。
烧结可以以粉末状的原状对混合物进行烧结，也可以成形之后进行烧结。粉末状的混合物，可通过例如加压成型法等方法成形。
烧结温度除了易于生成钛酸铝镁之外，由实用性的观点出发，通常为1300℃-1600℃，优选为1400℃-1550℃。达到烧结温度的升温速度通常为10℃/小时-500℃/小时。
烧结通常在大气中进行，但是，根据所使用的原料，也即氧化铝源、氧化镁源及氧化钛源、以及使用二氧化硅源时的二氧化硅源的种类和使用量比，也可以在氮气、氩气等惰性气体中进行烧结，在一氧化碳气体、氢气等还原性气体中烧结也可以。另外，也可以减低氛围中的水蒸气分压进行烧结。
烧结通常使用管式电炉、箱式电炉、隧道式炉、远红外线炉、微波加热炉、竖井式炉、反射炉、旋转炉、辊底式加热炉等惯用的烧结炉进行。烧结可以间歇式进行，也可以连续式进行。另外，可以静置式进行，也可以流动式进行。
烧结所需要的时间，只要是对于由混合物生成为钛酸铝镁来说足够的时间即可，根据混合物的使用量、烧结炉的形式、烧结温度、烧结氛围等有所不同，通常为10分钟-24小时。
通过对混合物进行烧结，使混合物成形后进行烧结时，能够得到钛酸铝镁-氧化铝复合陶瓷的成型体，以粉末状的原状对混合物进行烧结时，能够得到粉末状的钛酸铝镁-氧化铝复合陶瓷。通过烧结得到的粉末状的钛酸铝镁-氧化铝复合陶瓷可以用通常的方法，例如加入水等进行成形的方法成形，通过烧结成形后的成型体，也可以得到烧结体。
在式(1)-(3)中，x的值可通过镁源及钛源的使用量、以及烧结条件(压力、温度等)进行控制。此外，a的值则可通过氧化铝源的使用量、镁源和钛源的使用量、以及使用兼有氧化铝源的化合物作为二氧化硅源时其的使用量进行控制。进而，b的值可通过二氧化硅源的使用量进行控制；使用铝硅酸盐作为二氧化硅源时，c、d及e的值可通过其组成及使用量进行控制。
