XRF and Raman Characterization of Antimonite

Instrumentation Science & Technology, 2009
Abstract Two type Antimonite (stibnite) ore samples were analyzed by polarized energy dispersive X-ray fluorescence (PEDXRF) spectrometry and by confocal Raman spectrometry (CRS) in this study. The samples were collected from two different localities (Izmir-Odemis and Bursa-Uludag zones from Turkey) according to the sampling methods. The first locality

Paintings? a challenge for XRF and PIXE analysis

X-Ray Spectrometry, 2000
Conventional pigment analysis of paintings requires the removal of micro-samples followed by the preparation of cross-sections. There are also requirements for investigating several locations within a painting in order to obtain information about dating and provenance or the reason for aesthetic impressions of the paint materials. The need to carry out

Enamel paint techniques in archaeology and their identification using XRF and micro-XRF

Radiation Physics and Chemistry, 2017
Abstract This investigation focuses in detail on the analysis of discoveries in South Moravia – important sites from the Roman period in Pasohlavky and Musov. Using X-ray fluorescence analysis and micro-analysis we help identify the techniques of enamel paint and give a thorough chemical analysis in details which would not be possible to determine by

Alumina Characterization by XRF

Advances in X-ray Analysis, 1989
One of the most important properties that characterizes alumina is its elemental composition. Although XRF has been applied to the analysis of aluminas for the past three decades, special aluminas have always presented a maj or challenge. Moreover, only recently did it become possible to analyze for light elements such as Na. Two new sample preparation
