Yttrium oxalate may be dehydrated in vacuum at a temperature as low as 260 deg , and decomposition of the oxalate itself begins upon completion of dehydration. In vacuum as well as in an open furnace, various carbonato-oxalates and oxycarbonates are

It is shown that the first step in the thermal decomposition of europium(III) oxalate leads to reduction to the divalent state. In an oxidizing atmosphere the europium is reoxidized and continues decomposing gradually to Eu2O3 at 390°. In an atmosph

The decomposition of mixtures of metal oxides with NOClO4 or NO2ClO4 was studied by gasometry, thermogravimetry, D.T.A. and i.r. absorption. It is shown that NOClO4 is first converted to NO2ClO4, which reacts with some of the oxides to form the corre

The thermal decomposition of NOClO4 (powder, or fragments of pressed pellets) and of NO2ClO4 (granules) has been studied gasometrically and by X-ray diffraction. During the decomposition of NOClO4, NO2ClO4 is formed as an intermediate. The following

Anhydrous lanthanum oxalate is stable at 320°C. On heating this salt at higher temperatures intermediates are produced which appear to correspond to definite compositions, but they are contaminated with finely dispersed carbon. The course of the dec

The reaction at 300°C between molten lithium perchlorate and chromium(III) oxide gave lithium dichromate. When lithium perchlorate and chromium(III) oxide were in the formula weight ratio of 2:1 respectively, the chromium was oxidized completely int

The influence of the oxides TiO2, V2O5, Co2O3, MnO2, Fe2O3, Co2O3, NiO, CuO, La2O3, CeO2, Pr6O11, Eu2O3, Gd2O3 and Tb4O7 on the thermal decomposition of lithium perchlorate trihydrate, was surveyed. Most of the oxides lowered the decomposition temper

The paths followed in the thermal decomposition of ytterbium oxalate depend on the external conditions. Partial reduction to divalent ytterbium occurs in vacuum. These results confirm previous postulates: (a) that in solid reactions of the type solid

The thermal decomposition of the light rare earth oxalates was studied in vacuum in the temperature range 340–440°C. The behaviour of the whole group (with the exception of europium oxalate) was analogous to that of lanthanum oxalate. The relative
