Different Types Of Clay Used In Making Ceramics African ...

2021-11-30  The poor plasticity of kaolin is chiefly due to its relatively large particle sizes. Consequently, pre-fired kaolin ceramics can easily tear when bent, if in a moist unfired state (i.e. moisture levels are suboptimal). Of all classes of clay, kaolin has the highest temperature maturity levels (high-fire clay) with temperatures as high as 1,800 °C.

The application of clay minerals in ceramics - ScienceDirect

1991-3-1  APPLICATION OF CLAY MINERALS IN CERAMICS 431 Kaolin is used in whiteware bodies for its resistance to temperature, its re- liable thermal expansion properties and, of course, its fired color which is normally white to buff. Ball clay properties play a more varied role in white- ware formulations, however.
