Abstract

In the framework of valence electrons collectivization theory, estimates of characteristic pressure values, which can cause superconductivity of hydrogen compounds (hydrides) at elevated temperatures up to room temperature, are made. The calculated values are compared with experimental data obtained in the study of compounds LaH10: Тс ≈ 250 K, Р ≈ 170 GPa.

Key words: HTSC, metal-hydrogen compounds.
