在通过核反应~(24)Mg(d,a)~(22)Na制备~(22)Na时,我们曾考虑用MaO作靶,因此研究了电泳法制备MgO薄层的条件。选用丙酮作介质,用超声波发生器制备了MgO的比较稳定的悬浮体,以Pt片作阳极,以Cu片为阴极进行电泳,研究了电泳的电压、产额(Y)和悬浮液浓度(C)、电泳时间(t)的关系以及一些添加剂对薄层的影响。 We have considered the use of MaO as a target for the preparation of ~ (22) Na by the nuclear reaction ~ (24) Mg (d, a) ~ (22) Na, so the conditions for the preparation of MgO by electrophoresis were studied. Acetone was used as a medium to prepare a relatively stable suspension of MgO using an ultrasonic generator. Pt as an anode and Cu as a cathode were used for electrophoresis. The effects of voltage, yield (Y) and concentration of the suspension (C) ), Electrophoresis time (t) and the effect of some additives on the thin layer.
