In order to obtain data for a prospective powder data file for dental gold alloys X-ray diffraction photograms of 75 different gold alloys were taken using a Guinier-Hägg camera and CuKalpha1 radiation. Before the X-ray photograms were taken the alloys had been heat treated at 700 degrees C, 800 degrees C or 900 degrees C depending on the solidus temperatures of the alloys. The lattice parameters of the samples were determined from the X-ray photograms. These data were supplemented by a specification of the interplanar spacings of the three strongest lines on the diffraction patterns and also by the relative intensities and Miller indices of these lines. An extensive library of reference films is to be collected and this and other details of the file are discussed. It is not intended that the file be used to identify a particular alloy but merely to identify the type of alloy. Thus it can serve as a guide to facilitate the proper selection of gold alloys within practical clinical dentistry.
为了获取牙科金合金预期粉末数据文件的数据，使用吉尼尔-哈格相机和CuKα1辐射拍摄了75种不同金合金的X射线衍射照片。在拍摄X射线照片之前，根据合金的固相线温度，对合金进行了700℃、800℃或900℃的热处理。从X射线照片中确定了样品的晶格参数。这些数据还补充了衍射图谱上三条最强线的晶面间距规格，以及这些线的相对强度和密勒指数。将收集一个广泛的参考胶片库，并讨论该文件的这一内容和其他细节。该文件并非用于识别特定合金，而仅仅是识别合金类型。因此，它可以作为一个指南，便于在实际临床牙科中正确选择金合金。
