“…Details of the image acquisition system have been published elsewhere [1]. Due to the high dynamical response and linearity of our X-ray detector [3] we are able to perform quantitative image analysis. In particular we are able to extract the absolute values of the source material density within an error of less than 20%.…”

“…78 The position sensitive detectors based on CCDs or linear proportional counters are limited in their spatial resolution or could be very expensive if designed to cover the broad range of angles usually required in powder diffraction experiments. The IP-detectors, on the other hand have been developed in various configurations ranging from flat plates [79][80][81] , to cylindrical curved plates. [82][83][84][85][86] The usual limitations encountered with the IP detectors pertain to the requirement for an external IP scanner.…”

This project was aimed at developing the foundation, based on existing knowledge of various high temperature material properties, to explore new ceramic materials with interesting phase transformation properties. The systems focused on were one and two component oxide ceramic systems with the potential for application in the aerospace industry, namely, high temperature, chemically stable, oxide ceramics. A thorough evaluation of literature was conducted to identify three to five key ceramic oxide materials that may have promising high temperature phase transformation behavior. Eventually, based on literature and PIs extensive knowledge on phase transformations in oxide ceramics, four candidate ceramic oxide materials were identified for in-depth investigation of their high temperature and phase transformation properties by state-of-the-art, in-situ high temperature experimentation which included DSC/TGA, dilatometry and high temperature X-ray diffraction using synchrotron radiation. These included (a) Y 2 SiO 5 , (b) CaWO 4 , (c) CePO 4 and (d) YTaO 4 .

“…Construction of a fast PSD system to cover a wide 2 range with adequate spatial resolution can be expensive, particularly in systems which use linear sensitive proportional counters or CCDs. IP detectors which use a phosphor film tend to be less expensive and have been developed both as flat plates (Gualtieri et al, 1996;Rizzo et al, 1995;Thoms et al, 1996) and as cylindrical curved detectors (Fujiwara et al, 2000;Garrett et al, 1995;Kellermann et al, 2001;Nishibori et al, 2001a,b). However, one problem with the IP detectors has been the delay in data acquisition, either owing to the size of the area detector or to the requirement of an external scanner, which can also compromise reproducibility.…”
