Phase Fun With Feldspars: Simple Experiments to Change Chemical Composition, State of Order, and Crystal System part of Mineralogy:Activities
Students will use X-ray diffraction to determine the composition of an "unknown" feldspar and then perform experiments to change the phase and composition of the feldspar.
Determination of Chemical Composition, State of Order, Molar Volume, and Density of a Monoclinic Alkali Feldspar Using X-Ray Diffraction part of Mineralogy:Activities
This activity involves using XRD to determine the chemical composition, state of order, molar volume, and density of a monoclinic alkali feldspar.
