CERAMIC MATERIALS
Normal ceramics lack ductility and, in order to obtain this, heterogeneous metal-ceramic ( cermet'') mixtures have been proposed. Continuous distribution of the metal phase is difficult to achieve, but it has been observed that metal-ceramic-distribution may be effected by the dissociation or splitting up of a chemical sub-compound or solid solution on cooling into metal and non- metal phases. A mixture of a refractory compound of a metal (thoria powder) and the metal (thorium metal powder) is heated to a high temperature in an inert atmosphere or in vacuo and then cooled. The proportions are so chosen that the product splits up into metal and non-metal phases (thoria powder 5.8 pans, thorium metal 18.8 parts).
