A water‐based method for producing aluminum oxynitride (AlON) green bodies with a relatively high density is described. While alcohol is usually the medium for ball milling, this approach utilizes water to form a rigid network of aluminum hydroxide in Al 2 O 3 –AlN preforms. Al 2 O 3 –AlN preforms were prepared by four different routes based either on alcohol or water‐based slips, and underwent identical sintering procedures. Samples prepared using the water‐based method and pressure filtration reached a green density of 67%, compared with 52% and 47% for samples prepared from alcohol‐based slips and formed using pressure filtration and dry pressing, respectively.
