Abstract

In the present studies the effect of di-potassium hydrogen phosphate binder on sintering behaviour of pyrophyllite mineral has been investigated with a view to develop pyrophyllite based ceramic tiles. The various process parameters namely effect of binder content, particle size of pyrophyllite powder, compaction pressure and sintering temperatures have been optimized to make tiles possessing properties as per the requirement of Indian Standard specification. The formation of different phases formed on sintering of optimised composition has been investigated using X-ray powder diffraction technique. The thermal analysis of optimised composition has been studied with a view to understand the various thermal changes and various phase transformations taking place up to 1200°C temperature. The molecular bonding of aluminum phosphate and silica linkages have been studied by recording IR- spectra of optimised composition sintered at different temperatures. The morphology of aluminium phosphate and dehydroxylated has also been studied using scanning electron microscopy. The results of these studies are presented in this paper.
