Abstract: The synthesis of superhard materials is an interesting research subject in the field of materials
science. Recently, experimental and theoretical research activities on materials with an hardness comparable to or higher than diamond have
been stimulated by the postulation and discovery of novel carbon- and boron-based superhard materials. Besides diamond and c-BN, β-C3N4,
c-BCN and fullerenes are also potential candidates for superhard materials. This review deals with the latest research progress in the field of novel carbon- and boron-based superhard materials.

Key words: superhard materials, B-C-N system, carbon-based materials, boron-based materials
