MISC

  1. 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．
  2. Adsorption of metallic ion by phosphorylated rice husks , 芦田 利文 , 近畿大学工学部研究報告 , 42 , 42 , 1 , 5 , Dec. 2008
    Summary:もみ殻を粉砕しリン酸化処理を施し，リン酸化もみ殻を調整した．リン酸化もみ殻のイオン吸着能を検討した．もみ殻の前処理がリン酸化率に大きな影響を及ぼすことが分かった．
  3. Refinement of zirconia by mechanochemical reactions between zircon and barium salt , ASHIDA Toshifumi; IMABAYASHI Hidekazu; KUME Atsuzi; KANEKO Yoshihisa , Research reports of the Faculty of Engineering, Kinki University , 38 , 9 , 13 , 20, Dec. 2004
    Summary:Zircon ore flour was mechanically milled with barium salts up to 40 hour with a vibrating ball mill. The sample milled were investigated by X-ray diffractometry to confirm the process of mechanochemical reaction. Zirconium oxide was observed in milling with barium oxide and with barium hydroxide. No rection was observed in milling with barium carbonate. The sample milled was leached for 3hr in 6M-HCl at 80℃. Zirconium oxide was refined from the filtrate by adding DL-mandelic acid. The yields of zirconium as zirconia reached 65% in milling with barium oxide, 15% in millling with barium hydroxide, and 22% in milling without barium salts, respectively. In each case, the yields remained unchanged in milling for more than 20 hours.
