Abstract

Microstructure of commercial dental alloys and their amalgams were studied primarily by x-ray diffraction, optical metallography, scanning electron microscopy, and x-ray energy dispersive spectroscopy. X-ray diffraction revealed more phases than normally reported in these materials. Presence of new phase was discussed and their formation mechanism understood. Some phases having interacting 2 theta degrees values with others were properly identified. Both new and conventional dental alloys and their amalgams, namely Tytin, Sybraloy, Dispersalloy, Kerr Spheraloy, Caulk Spherical, Shofu Spherical, and Caulk 20th Century Microcut were used to complete the investigation.

摘要

主要通过X射线衍射、光学金相显微镜、扫描电子显微镜和X射线能谱对市售牙科合金及其汞齐的微观结构进行了研究。X射线衍射显示出这些材料中比通常报道的更多的相。讨论了新相的存在及其形成机制，并对其有所了解。正确识别了一些与其他相具有相互作用的2θ值的相。使用新型和传统牙科合金及其汞齐，即钛锡合金、赛布拉洛伊合金、分散合金、克尔球形合金、考克球形合金、松风球形合金和考克20世纪微切合金来完成这项研究。
