Instructor-prepared materials will be used for this class,
so No Text will be Required
(however, several texts are recommended depending on individual student needs.
Click here for a short list of texts which
you may be interested in acquiring.)
Prerequisites
Successful completion of Mineralogy (EPS 301) or an equivalent Mineralogy or
Materials science course from another institution is highly recommended but
not absolutely required. A fundamental backround in scientific methods, geometry,
trigonometry and algebra is essential, and some more advance mathematics is
desirable (though not absolutely necessary). Undergraduate and graduate students
from other departments may enroll in the course with permission from the instructor.
The course is available for graduate credit to E&PS graduate
students who complete an additional research project -- see your instructor
for requirements.
Radiation Safety Exam
All students enrolled in the class (including any auditors) must
take and pass the Radiation Safety Exam for XRD users before being allowed to
use the laboratory. This should be completed by no later than
March 7th (before Week 8). The exam is administered by the Radiation Safety
group of the Safety, Heath and Environmental Affairs (SHEA) office. Most of
what you need to know for this exam will be covered in Week 2 (and in related
reference material), and it is your responsibility to complete this requirement
in a timely manner. Please see our "Requirements
for Users" page for details about who to contact.

Synopsis of Course
An introduction to the use of X- ray Powder Diffraction as an analytical method. The course will emphasize the practical use of X-ray diffraction as an analytical tool for the identification of crystalline materials in minerals, rocks, soils and engineered materials. Topics to be covered:
Some hands-on laboratory exercises will supplement lecture topics.
Note: The revision dates for course materials are listed below. Those without a current (2007) revision date have not been updated from the previous time the course was offered.
Another source of online resources is our lab's XRD Resource page. Here you will find links to online tutorials on topics related to XRD, equipment manufacturer's web pages, and a variety of resources to supplement the course materials linked below.
These materials form the required text for this class. Students are responsible for the material contained in the Acrobat PDF files listed below regardless of whether that material is covered directly in class.
Acrobat PDF Note: To view the Acrobat PDF files in your web browser, just click on them. To download the files so you can have a copy for reference, use your right-Mouse button (Mac users, just hold the mouse button down) and choose to "Save Target as .." or "Save Link As. ." to save a copy of the file. The files may be printed from your Web browser or from Acrobat Reader after downloading. Sometimes files will print more reliably if downloaded first and printed directly from Acrobat Reader (than if printed from your web browser).
PowerPoint Note: The online PowerPoint included here are "single-page webpages" of the "MHT" variety. These are usually very large (6 to 14 MB) because they include all the graphics in the presentation in a single file but usually display more reliably than the versions that access separate graphics files. They basically work just like a regular PowerPoint slide show. To make them work on your computer you will need the following:
Because these files are usually very large (since all graphics are included) and will take a long time to download on anything but a high-speed connection. If loading in directly in Internet Explorer, they will open a new, blank window while downloading, but it is strongly suggested that you download the files to your local system (Right-click and "Save file as . . " or "Save Link") and open them after they have downloaded. These files may also be opened directly in Powerpoint (if you have that program) or using Microsoft's free PowerPoint viewer. The 2007 version the the viewer is downloadable at: ftp://eps.unm.edu/pub/microsof/PPntView2007.exe.
