ABSTRACT
Pyrocarbons are dense carbons with structures close to graphite, i.e. formed by a stacking of graphene layers containing 2D, 1D or point defects. They are prepared by a gas-phase route such as chemical vapor deposition, and so have a variable nanotexture. This article describes their processing and characterization techniques, and their structural and textural classification, in relation with their properties, which make them useful in numerous high-tech applications.

INTRODUCTION
pyrocarbons are dense carbons with a graphite-like structure, consisting of a stack of graphene layers containing 2D, 1D and point defects. They are generally produced from the gas phase, by chemical deposition. As a result, their nanotexture is variable.
In this article, the main ways in which pyrocarbons are developed, characterized and classified structurally and texturally are discussed, along with the relationship with their properties, which lead them to be used in many high-tech applications.

They are prepared by a gas-phase route like chemical vapor deposition; accordingly, they have a variable nanotexture. This article describes the processing and characterization techniques, their structural and textural classification, in relation with their properties, which lead them to be used in numerous high-tech applications.
