Ceramic materials colour pigments

A ceramic material is a hard, high melting solid which is 

An opacifier is a glaze additive that makes an otherwise 

Superconductors have been applied to develop train systems that operate with magnetic-levitation (MAGLEV) in which the train effectively travels sslOmm above its tracks, i.e. virtually frictionless motion. The first commercial train came into service in Shanghai in 2003 and can reach speeds of 440 km h.  

Ceramic materials are commonplace in everyday life, e.g. floor and wall tiles, crockery, wash-basins, baths and decorative pottery and tiles, and also include the cuprate 

9) as colour pigments. One of the factors that has to be taken into account when choosing a pigment is the need for it to withstand the high hring temperatures involved in the manufacture of ceramics. This is in contrast to the introduction of pigments into, for example, fabrics.

The topics chosen for inclusion in this chapter reflect areas of active interest and elaborate upon some topics that have been given only brief mention in earlier chapters. In describing the chemistries of the d- and /-block metals in Chapters 21,22 and 24, we included many examples of solid state compounds, and we now look further at electrical conducting and superconducting properties. At various points in the book, we have mentioned colour pigments in ceramic materials when...
