Ceramic-Based 3D Printed Supports for Photocatalytic Treatment of Wastewater

Figure 10

Several 3D printed square pieces of CaSO₄ were used to optimize the infiltration process with Ludox. All the samples were infiltrated with a solution of Ludox : water with a ratio of 1 : 5 (wt) for 30 s and then dried for 10 min at 70°C and finally they were fired at the temperatures shown in the images for 2 h.
