Formation of new functional materials and device heterostructures on the basis of nanosystems of superionic conductors

Search for conditions of conservation of fast ionic transport (FIT) in nanosystems of advanced superionic conductors (ASIC)[1-4] and synthesis of new types of device thin-film heterostructures on this basis is a fundamental scientific problem. ASICs (α-AgI, solid electrolytes of the family RbAg4I5, etc. ) are crystals with a record high level of ionic conductivity and a low value of activation energy E～0. 1 eV.

用氮气和戊基黄药浮选时黄铁矿的低电位疏水状态

为了解释和查明N2TEC浮选法的基本原理，本文报道了在用戊基钾黄药(PAX)作捕收剂时，黄铁矿的低电位疏水状态的研究成果。新制定的N2TEC浮选法的目的是提高难处理含金硫化矿金回收率。在典型的N2TEC浮选法中，用氮气代替空气作为浮选气体，戊基钾黄药作为评选含金黄铁矿颗粒的捕收剂。l997年3月，第一个N2TEC浮选工艺在内华达州Lone Tree矿山浮选厂投产，一直操作至今。根据电化学校制接触角测量结果，研究了黄铁矿的低电位、低pH疏水状态与浮选变量(pH、气相组成、捕收剂浓度和黄铁矿电位)之间的关系。
