Abstract
Triaxial ceramic bodies used for the manufacture of tableware, electrical porcelain, sanitaryware etc contain feldspar, quartz and clays as the main ingredients. Feldspar serves as a flux in these bodies for achieving proper bonding among different particles. Silica is commonly used as a filler which imparts rigidity to the fired wares and lowers the drying shrinkage of clay bodies, and thus, reduces drying cracks in the green stage. This is also preferred because of its low cost and abundance in pure form. Quartz is, however, non-plastic and its addition•makes the body more fragile. Clay adds plasticity and enables shaping of the green ware into the required form; on heating, it decomposes to mullite, which adds to the strength of the ceramic ware.
