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. |
