Elemental analysis of two precious alloyceramic systems revealed the accumulation of Sn atoms within the interaction zone of couples subjected to a range of metal oxidation time; and varying total firing times. The source of Sn atoms which accumulated within the interaction zone was the opaque porcelain layer which contained an initially higher Sn concentration than the alloy. It is hypothesized that SnO2 provides continuity of electronic structure between alloy and ceramic structures and is a primary factor in controlling ceramic-metal adherence.
对两种贵金属合金-陶瓷系统进行的元素分析表明，在经历了一系列金属氧化时间和不同总焙烧时间的试样的相互作用区内，锡原子发生了累积。在相互作用区内累积的锡原子来源是不透明瓷层，该层最初的锡浓度高于合金。据推测，二氧化锡在合金和陶瓷结构之间提供了电子结构的连续性，并且是控制陶瓷与金属结合的主要因素。
