A conventional (Minimax), two single-particle high-Cu (Summalloy and Aristaloy CR), and two dispersed-phase (Cluster and Phasealloy) amalgam alloys were each admixed with 0.5 wt% of CuF2, InF3, SnF2, and CaF2, and evaluated for F-, Cu, and Sn release, as well as for corrosion resistance, microstructure, and compressive strength. Over a 43-week interval, only Cluster revealed somewhat of a sustained F- release in artificial saliva. A ranking for F- release was Cluster (highest), Summalloy, Phasealloy, Minimax, and Aristaloy CR. The effectiveness of the F- compounds in releasing F- followed CuF2 (highest), SnF2, InF3 (1.0%), InF3, and CaF2. Amalgams with admixed CuF2 released both the most Cu and increased Sn. For three amalgams, CaF2 admixtures also increased the Cu release. Constant-potential coulometry distinguished among the different fluoride amalgams. Only Minimax revealed a significant reduction in compressive strength with two admixtures. Microstructural analysis revealed an increased pore distribution around the Ag-Cu dispersed particles, and it was assumed that the F- particles were contained within the pores, since SEM, EDS with a low element detector, and ESCA were all unable to detect the F- particles.
一种传统的（极小极大值）、两种单颗粒高铜（Summalloy和Aristaloy CR）以及两种分散相（Cluster和Phasealloy）汞合金分别与0.5 wt%的CuF2、InF3、SnF2和CaF2混合，并对其氟离子、铜和锡的释放情况以及耐腐蚀性、微观结构和抗压强度进行了评估。在43周的时间间隔内，只有Cluster在人工唾液中表现出一定程度的持续氟离子释放。氟离子释放的排名为Cluster（最高）、Summalloy、Phasealloy、Minimax和Aristaloy CR。氟化合物释放氟离子的有效性顺序为CuF2（最高）、SnF2、InF3（1.0%）、InF3和CaF2。混合有CuF2的汞合金释放的铜最多，锡含量也增加。对于三种汞合金，添加CaF2也增加了铜的释放。恒电位库仑法区分了不同的氟化物汞合金。只有Minimax在添加两种混合物后抗压强度显著降低。微观结构分析显示，在银 - 铜分散颗粒周围的孔隙分布增加，并且由于扫描电子显微镜（SEM）、配备低元素探测器的能谱仪（EDS）和光电子能谱（ESCA）均无法检测到氟离子颗粒，因此推测氟离子颗粒包含在孔隙中。
