Fabrication of porous ceramic via recycling of glass with paper fiber as sacrificial fugitive

Recycled glass powder was added with ball clay and feldspar using ratio 90:5:5. The blend were mixed into different amount of paper fiber and cast into porous ceramic. Samples prepared with different compositions (2, 4, 6, 8, and 10 wt % of paper fiber) were heat treated at constant temperature (750 °C) for an hour. Samples with high percentage of paper fiber gave the largest pore size in the ceramic body, meanwhile lower percentage of paper fiber produced ceramic body with smaller pore size.
