Refractory Oxides | SpringerLinkLast updated: September 1, Y ou started your morning with ceramics—and they'll dominate your day. Inside your brick, cement, and glass home, you woke to the quartz clock, washed in the tiled bathroom, breakfasted on pottery cups and bowls. Maybe you worked all day at a computer packed with ceramic-based electronic components, like microchips , capacitors , or resistors , before heading back home for a glass of wine, gobbled down dinner from those same pottery plates, and sat in front of the liquid-crystal TV or Gorilla glass smartphone , before heading for bed and setting the quartz clock, ready to repeat again tomorrow. Though it's far from obvious, we live in a ceramic world, just as people have for thousands of years.

The thermal and mechanical properties of these ceramics often limited the size of objects that could be cast in a single process in the pre-Classical Old World the availability of large quantities of very fine-grained loess clays was probably a decisive factor behind the astonishing levels of piece-mould casting achieved in Bronze Age China.

Ceramics are essential for our day to day life. It is useful from clay products to porcelain. Generally, a ceramic is a non-metallic, solid inorganic compound. Earlier ceramics were used only for pottery. Now, with the changing times, ceramics are more and more used only for specific purposes. Use of ceramics has been from ancient times. Based on these uses there are three basic types of ceramics:.
