X-ray investigation of the equilibrium phase diagram of CH4-N2 solid mixtures

The phase diagram of solid methane-nitrogen mixtures is investigated by x rays. The boundaries of the maximum reciprocal solubility of the components are determined in the temperature range from 5 °K to the melting point of the mixture. The lattice parameters and molar volumes of the observed phases are studied as a function of temperature and concentration. Negative thermal expansion is found at certain temperatures and concentrations of nitrogen in methane crystals.
