blended in a highenergy ball mill for 10 hours using a 304 stainless steel ball of 12 mm in diameter. The ball to powder ratio was 10:1 and 5 wt. % paraffin wax was used as a binding agent. The resulting mixture was poured into a mould to form a prefabried bulk ceramic (preform), ovendried at 50 0C and sintered at over 400 0C.

 · By ball milling, the surface of particles is rubbed against balls, and the friction between particle/ball breaks the bonds of functional groups like Si O Si on the surface of particles. This study shows how nonfiring sintering is effective for solidifying silica (SiO 2 ) powders, where high relative densities are obtained.
