The heat decomposing process of REPO4 was tested with TG-DTA experiments. The results showed that the decomposition temperature of REPO4 with CaO was reduced because of adding NaCl-CaCl2 mixture （NaCl：CaCl2 = 1：1 ）. The influence of the addition of NaCl-CaCl2, roasting temperature and roasting time on decomposition ratio of REPO4 with CaO was studied. The results showed that the decomposition ratio of REPO4with CaO was 79% when the addition percentage of NaCl-CaCl2 was 10%, the roasting temperature was 750℃, and the roasting time was 1 h.展开更多

Given that the global financial crisis was mainly triggered by the collapse of the collateral pool for dealer-based credit intermediation, this issue needs to be resolved quickly for normalized credit supply. Primarily, increased supply capacity for safe assets that can serve as valid collateral is the key agenda. This would be possible with a better use of USTs that are kept in EME silos and a broader recognition of an emerging market sovereign collateral pool. The inclusion of new collateral into the expanded and invigorated repo system that includes Asia would stabilize global capital flows and improve financial stability. In a related context, a market-driven, risk-mitigating regional repo market initiative would also bring balance to an increasingly market-driven financial ecosystem and mitigate the global shortage of safe assets.展开更多
