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 formed in the temperature range 300 to 420 deg . Disproportionation of the carbon monoxide originating from the initial decomposition of the oxalate takes place to an extent of nearly 60%. The carbon thus deposited stabilizes the oxycarbonate and CO and CO/sub 2/ are evolved only on heating at 700 to 1000 deg . In an oxidizing atmosphere the carbon is burned away, and white Y/sub 2/O/sub 3/ may be obtained at 420 deg under proper conditions. (auth)
