Copper/zinc oxide mixtures show strong synergistic effects when used together as catalysts, particularly in methanol synthesis and water-gas-shift reactions. The authors have employed semiempirical quantum-mechanical calculations (INDO) to study the electronic properties of ZnO, CuO, and CuO/sub 2/ clusters (less than or equal to 26 atoms), of Cu ...

A METHOD for determining excess zinc in zinc oxide has been devised1. It is based on measurement of the hydrogen produced by the excess metal when the sample is dissolved in hydrochloric acid. It will detect 0.05 µgm. of excess zinc. This communication summarizes the results obtained by the method with oxide in various states.

Interstitial zinc in zinc oxide
Journal of Physics and Chemistry of Solids, 1957Abstract Methods of introducing interstitial zinc into single crystals of zinc oxide are described which involve heating the crystals in zinc vapor followed by rapid quenching. The interstitial zinc atoms act as donors with a low ionization energy and they are observed by the extra conductivity which they impart to the crystals.

An overview is given of zinc oxide varistors, which are made of semiconducting ceramics with highly nonohmic current-voltage characteristics, which originate at the grain boundaries. These varistors are widely utilized to protect electric power lines and electronic components against dangerous voltage surges.
