@article{oai:ous.repo.nii.ac.jp:00000414, author = {土井, 章 and Doi, Akira and 河田, 幹夫 and Kawada, Mikio and 加藤, 忠蔵 and Kato, Chuzo}, journal = {岡山理科大学紀要, Bulletine of Okayama University of Science}, month = {Dec}, note = {P(論文), The so far obtained reports have shown that three endothermic peaks at 200~500℃ or the one endothermic peak at 216℃ appeared on the DTA curve of Cd(CH)_2 under the atmosphere air. In this report the thermal decomposition process of Cd(OH)_2 was studied by means of DTA and TG under atmosphere CO_2,N_2 and air. The DTA and TG curves under the atmosphere CO_2,N_2 have not been reported. The one exothermic peak and two endothermic peaks appeared on the DTA curve under the atmosphere CO_2. This exothermic peak was considered to be due to the formation of CdCO_3 and also the two endothermic peaks due to the decomposition of Cd(OH)_2 and CdCO_3. The formation reaction of CdCO_3 occured during the decomposition of Cd(OH)_2,and then the decomposition of CdCO_3 took place when the decomposition of Cd(OH)_2 was completed. It was considered from the results obtained that the following reactions occured during the thermal decomposition of Cd(OH)_2 under atmosphere CO_2 : endothermic peak at 265℃ Cd(OH)_2→CdO+H_2O exothermic peak at 240~340℃ CdO+CO_2→CdCO_3 endothermic peak at 468℃ CdCO_3→CdO+CO_2}, pages = {151--158}, title = {CO_2, N_2および空気雰囲気下におけるCd(OH)_2のDTA曲線}, volume = {7}, year = {1971}, yomi = {ドイ, アキラ and カワダ, ミキオ and カトウ, チュウゾウ} }
