文档介绍：Traditional Ceramics NO. 120120076 Name: Qiang Xue Traditional Ceramics ponents Traditional ceramics are made from three ponents : clay , silica(flint), and feldspar. ? Clay consists mainly of hydrated aluminum silicates with small amounts of other oxides such as TiO 2 , Fe 2O 3 , MgO, CaO, Na 2 O, and K 2 O. Table 1 lists the positions of several industrial clays.

Silica The silica(SiO 2 ),also called flint or quartz, has a high melting temperature and is the ponent of traditional ceramics. ? Feldspar Potash feldspar, which has the position K 2O· Al 2O 3· 6SiO 2 , has a low melting temperature and makes a glass when the ceramic mix is fired. It bonds the ponents together.
