Ball milling was carried out in an 80 mL alumina vial under an ambient atmosphere using fourteen zirconia balls (10 mm dia.) by a high-energy ball mill (MSK-SFM-3, MTI Corporation, Richmond, CA, USA) with a rotational speed of 1200 rpm. The powder-to-ball mass ratio was kept at about 1:5 in all the experiments.
Ball milling is a top down approach and a method to reduce size of particle while Zeolite is a valuable inorganic materials having wide variety of applications. In this paper, ball milling of commercial synthetic Zeolite powder was studied with their time varied. Wet ball milling was selected as a potential means to decrease the particle size of Zeolite over dry grinding.
consequently wet ground by 2 mm-ball milling at 500 rpm for 3 h in isopropanol. The TiO 2 solution was then dried in the oven at 110 °C for 24 h.
The resultant glass melt was quenched into deionized water as a preliminary step and then subjected to particle size reduction to 3–5 µm by ball milling, finally mixed and blended with 40 wt%−60 wt% Al 2 O 3 powders. The tape casting process was accomplished on a laboratory caster (BHLY-011A) with a single blade casting head.
