Transparent aluminum oxynitride ( AlON ) ceramics have been prepared through aqueous gelcasting forming technique starting from the raw materials of single phase powders. The powder was specially treated for anti‐hydrolysis in ethanol before shaping technique. surface‐treated powders could then be dispersed an aqueous‐organic solution to prepare stable slurries containing 35 vol% solids loading. obtained were subsequently casted, calcined, and pressureless sintered at 1950°C 8 h nitrogen atmosphere. High transparent with average grain size 112 μm in‐line transmittance 81% wavelength 1100 nm obtained.
