In order to prove sodium poisoning dose not effect the self
cleaning performance and to make use of technology commercially
viable, demonstration has been done on ceramic glazed tiles with
one square foot size substrate using permanent marker stain by
exposure to sun light. Fig. 9 shows 1 sq ft of glazed ceramic tiles
coated with TiO2 thin film using the optimized sol composition
using a manual spray gun and fired in a continuous belt furnace at
the production rate of 3.5 m2/h.
