| Abstract |
| Spodumene is well known as a lithia bearing nux and a low
expansion filler in whiteware bodies. In the present work,
an attempt has been made to develop a cost-effective
processing of mullite ceramics using spodumene at a nux.
It has been observed that mullite based ceramics can be
effectively prepared from low cost silica fume and electrostatic
precipitated alumina dust raw materials where
spodumene acts as a sintering nux. The latter (10 wt%)
has also been found to enhance the degree of mullitization;
however, an addition of 20 wt% spodumene lowers the
yield of mullite due to formation of a ~-quartz solid
solution. |
