Abstract
A study of the partial substitution of feldspar by Blast Furnace Slag (BFS) and its effects on the properties of sanitary ceramics, has been carried out. Characterization of rheological behavior, thermal, structural, physical, and mechanical properties of fired sanitary-ware bodies, show that 10wt. % is the optimal value for BFS in the formulation of sanitary ceramic. DRX, SEM, and FT-IR analyses confirmed that the starting crystalline phases (quartz and mullite), with the gradual appearance of anorthite, allow a non-negligible improvement in flexural strength (33 to 38 MPa), and a reduction in water absorption (0.35 to 0.10 %). From DTA/TG data, a little change in weight loss during the firing process (8.83 to 9.66 wt. %), was recorded. The Na-electrolytes with a mass ratio Na2CO3/ Na2SiO3 = 1.5, and a combined mass percentage (0.375 wt. %), are found to give the optimum values for good quality sanitary ceramic slip.
