MixiPol (3D Java Applet)

is Program of calculation and graphical imaging of full quasi-continuous X-Ray profiles of roentgenogram of polycrystal-phases and their mixtures at given concentrations (input BDQ-file is calculated by Developer and is kept in WWW-MINCRYST DB).

The program-applet is modified for using in two main variants with giving corresponding parameters.

  1. MixiPol-I calculates and images the profile of roentgenogram for the phase in corresponding Card of WWW-MINCRYST DB.
  2. Mixipol-II calculates and images the profile of roentgenogram of mixture of phases under the list, formed by User from WWW-MINCRYST DB. The wave length, CuKa or CoKa , is indicated by User.

The applet also is modified for calculation and the graphical imaging of roentgenograms in T-, T-and D-scales. The buttons starting variants of the applet are in the Menu of the Mineral Information Card.

The program-applet allows the user to allocate an angular interval and to detail the roentgenogram, increasing the image with orientation to the selected interval (Mode Zoom In) and to save this interval, with an opportunity of the addressing to it in the subsequent. Thus it is possible to reserve some variants of detailed representation of the roentgenogram according to a choice of different angular intervals with small intensity of reflexes. Separate reflexes of the roentgenogram can be identified and their given out characteristics (hkl, T, 2T, D) it is possible to specify with the call of BDQ-file (Modes Select + BDQ-file).

Mode Move allows looking through the increased variants of the roentgenogram.

Mode Hide/Tools allows to see on the screen the full image of the roentgenogram increased on a vertical with a part of elements of management or, accordingly, reduced with the basic part of elements of management.

Mode Intervals with two windows and two buttons (Delete, Add) allows to choose an angular interval with small intensity of reflexes and to increase its image together with the all roentgenogram. The beginning and the end of an interval is fixed in the right window and the interval can be added (Add) in the list formed in the left window. Button Delete eliminates useless intervals.

Mode Color allows the User to make the image more expressive - changing, by means of a special palette, color of the lines-curves representing components of a mix of the roentgenogram, the theoretical and experimental roentgenogram, a background and a framework, and also changing of type and thickness of lines.

Mode Texture allows to enter the textural multipliers modifying intensity of hkl-reflexes of the roentgenogram in one, two and even three directions, according to March-Dollase, Toraya-Rietveld and Rietveld (on the right in a window the help). The user chooses hkl-indexes of a texture and corresponding parameters of a texture and button Apply applies them.

Button Show angles shows the calculated angles of the texture (between the plane of a texture and other planes) from BDQ-file.

Mode Render Items allows to exclude/include the image of the corresponding components of roentgenogram temporarily.

Mode FWHM - allows to edition of parameters of full width on half of height (U, V, W).

Heading BDQ shows initial BDQ-file on the basis of which it is considered a polycrystal-roentgenogram. The BDQ-file calculates by the developer and is imported in WWW-MINCRYST DB.

Mode Other Parameters allows to switch on/off monochromator (for K-alpha2-component) and to choose type 100-ball normalization).

At last, the mode CONCENTRATION allows the User changing concentrations (within the limits of 100% - in sum) to model mixes of roentgenograms of crystal phases in the given concentrations.

Button WWW-MixiPol-2 starts the applet with input in corresponding scale (T, 2T or D) of roentgenogram. Procedure of formation of the list of the phases included in a mix is opened. After formation of the list the type of X-ray radiation - CuKa or CoKa -alpha must be indicated, since in Information Cards the different type of radiation for component of mixes can be specified.

Start of the prepared program by the result has the calculated initial roentgenogram of a mix of phases with equal concentration. The sum of concentration - 100% are strict. Further the User can vary concentration of phases (with the sum of 100%) just as also other parameters of the roentgenogram, with the purpose of modeling of quantitative composition of a mix comparison resulting profile of the roentgenogram of the mix with the experimental roentgenogram.

In summary we shall emphasize, that for convenience of comparison of resulting roentgenogram and experimental roentgenogram of mix is possible input of experimental roentgenogram in corresponding T- or 2T-scale and corresponding format and its superposition on the calculated model of roentgenogram of a mix.
