Mechanochemical synthesis of spinel and mullite powder using transition alumina
, 芦田 利文 , 近畿大学工学部研究報告 , 43 , 43 , 37 , 42 , Dec. 2009
Summary:複数の種類の遷移アルミナとMgOまたはSiO2とを混合し,メカノケミカル反応でスピネルおよびムライトの生成を検討した.室温におけるメカノケミカル処理だけでは,反応が進行しなかったが,生成温度はどちらも大幅に低下し,粉体原料の調整方法として有望であると考えられた. -

Synthesis of Vaterite by Carbonation Process in Aqueous System
, MATSUSHITA Isao; HAMADA Yukitoshi; MORIGA Toshihiro; ASHIDA Toshifumi; NAKABAYASHI Ichiro , Journal of the Ceramic Society of Japan , 104 , 1215 , 1081 , 1084 , 1, Nov. 1996
Summary:The synthesis of vaterite was attempted by carbonation process (Ca(OH)_2+CO_2→CaCO_3+H_2O) in aqueous systems with addition of organic compounds having amino group or carboxyl group such as amine, carboxylic acid salt and amino acid salt. Sodium L-glutamate, sodium L-aspartate and ethylenediamine are effective for crystallization of vaterite from amorphous calcium carbonate (ACC), as an initial product. ACC gradually crystallized to vaterite while releasing the additive and H_2O contained in ACC, under the absence of OH^- species in the liquid phase. The existence of OH^- in the liquid phase prevented strongly the formation of vaterite from ACC.
