Abstract: D R A W I N G
GROWTH OF CRYSTALS OF OXIDIC MATERIALS OF THE GARNET, ORTHOFERRITE AND SPINEL FERRITE STRUCTURES FROM LEAD OXIDECONTAINING FLUXES TO WHICH V2O5 IS ADDED YIELDS CRYSTALS OF INCREASED SIZE. IN CERTAIN SYSTEMS, NOTABLY OF THE ORTHOFERRITE STRUCTURE, CONTROL OF EASY DIRECTION OF MAGNETIZATION IS AFFORDED SO THAT PLATES WITH THE EASY DIRECTION NORMAL TO THE PLANE MAY BE REPRODUCIBLY GROWN.

Abstract: Catalyst members of the class exemplified by the nominal atom formula RE1 xPbxMnO3, in which Pb can be replaced by other divalent cations and Mn can be replaced by other trivalent cations, are activated by acid etching. The procedure is particularly efficacious where preparation is by ceramic firing techniques with activation making such materials comparable in activity to crushed single crystals of the same compositions. Activated catalysts of this class are useful for catalytic conversion of auto exhaust pollutants to non-toxic forms.

Abstract: Catalyst members of a class exemplified by La0.8K0.2MnO3 catalyze the conversion of NOx pollutants to the non-polluting materials N2O, N2, and O2. These compounds are also effective for promoting oxidation reactions such as CO to CO2.
