During the preparation of the quaternary oxidant tetraethylammonium iodate from the aqueous reagents, the residue after vacuum evaporation of most of the water exploded, breaking the flask. This was attributed to possible presence of excess periodic acid in the reaction mixture [1]. Further details and precautions to avoid heating the salt, normally stable in storage, are given [2],... [Pg.1561]

In 1988, Cava and co-workers also prepared (88a) a quaternary oxide, Ba/K/Bi/O, and observed superconductivity at -28 K. This compound was the first "non-transition metal" oxide with a Tc above the legendary "alloy record" of 23 K. Further studies indicated (88a) that the optimum composition for "high temperature" superconductivity in this system was Ba0 6K0 4BiO3 x, having a Tc of 30.5 K (Figure 17). The samples were multiphase, and the superconducting fraction varied from 3 to 25%. Superconductivity for the rubidium-substituted compound was observed at -28.6 K. [Pg.47]

Structure of YBa2Cu307. reproduced from G. F. Holland and A. M. Stacy, Physical Properties of the Quaternary Oxide Superconductor YBa2Cu3Ox, Acc. Chem. Res. 1988, 21, 8. One-dimensional Cu-O chains (shown in color) run along the crystallographic t>-axis, and two-dimensional Cu-O sheets lie in the a-b plane. Loss of colored oxygen atoms from the chains at elevated temperature results in YBa2Cu306. [Pg.342]
