Preparation of porous ceramic membranes from Sayong ball clay
The starting material was Sayong ball clay from Perak, Malaysia. The ball clay powder was sieved with a 75 µm mesh standard screen and mixed with corn starch (Glow-San Sdn. Bhd.) in a mass ratio of 70:30. The mixtures then underwent a dry milling process using a Lab Roller Mixer-LRM 30 (China, 40 alumina balls) at 140 rpm for 5 hours.Web
