1. The place of ceramics in the world of materials
To begin with, it's essential to define what a ceramic material is, and to situate it in relation to other materials. For the record, a "material" is a solid that has properties of use, i.e. "serves a purpose".
From a chemical point of view, the composition of ceramics corresponds to a combination of metallic atoms (such as aluminum, calcium, titanium, cerium...) and non-metals or metalloids (oxygen, carbon, nitrogen, boron and silicon).
The only ceramics that don't exactly match this criterion are a very small number of covalent compounds of boron and silicon with nitrogen and carbon, with special properties: Si 3 N 4 , SiC, BN, B 4 C and B ...
