Mechanochemical route for synthesis of spinel(MgAl_2O_4) and mullite(3Al_2O_3・2Si0_2)from several types of transition alumina were investigated. Spinel was mechanochemically synthesized without calcination，when the mixture of χ-Al_2O_3 and MgO was ground for 192 h with a planetary ball mill. When the other types of transition alumina，r，δ，θ and κ-alumina，were used as raw materials，no formation of spinel was observed only by mechanochemical process. By using the mixture ground for 24 hr，however，formation temperature of spinel decreased below 900 ℃. On the other hand，n o formation of mullite was observed in mechanochemical treatement by using the mixture of any type of transition aluminas and silica as a raw material. Calcination above 1000℃ caused the ground mixture to form mullite.
