The formula of the ternary so called x-phase in the Co-W-C system has been found to be f&W&. The structure has been determined from X-ray powder photographs. The crystal axes of the hexagonal unit cell with the atoms in the space-group Drr4 -P6Jmmc are c = a = 7.826 A. The cell contains two formula
Mixtures of N,O, and N,O, have been prepared from measured volumes of NO and 0,. Phase relationships in the system N,O,/N,O,, which depend on the composition of the samples and on the temperature, were studied by the Guinier technique and differential thermal analysis. Single crystals of phases A an
