grinding media was zirconia balls and milling time was 4 hours. After drying, the dried lumps were crushed and passed through the plastic sieve with an aperture size of 149 mm. The particle size and its distribution were determined with a laser particlesize analyzer (LS 230, Coulter Co., USA). The powder compacts were prepared by the diepressing technique. The pressure applied was 27 MPa

Yielding mass was subsequently grinded to form a fine powder by means of wet grinding in a planetary mill with 200 rpm for 2 h and with propanol as a milling media. Remaining propanol was removed by another calcification process at 700 °C for 2 h. Obtained mullite powder was uniaxially pressed into Φ 22 mm pellets with 100MPa pressure. The pellets were then sintered in static air at a

Key words: Kyanite, alumina, mullite, sinterization and attrition milling. Introduction Mullite (3Al 2O 3·2SiO 2) is the only stable compound (T mp ~1890 oC) in the Al 2O 3SiO 2 binary system at 1 atm pressure. It is an important phase in many traditional ceramics such as refractories and also in high technology applications for optical, electronic and structural components. Although
