Pearson's Crystal Data Features: Chemical system matrix

Features overview

The Pearson's Crystal Data software offers a special view of binary as well as multinary data called "(chemical) system matrix". It provides an overview of how many entries of the current answer set belong to a certain chemical system.
The screen shot shows the two-dimensional system matrix for the NaCl prototype, where the elements are sorted for atomic numbers.

The elements can be sorted in alphabetical order, for atomic number, periodic number, atomic size, atomic reactivity, and melting temperature. (For details, see: P. Villars, J. Daams, Y. Shikata, K. Rajan, S. Iwata, "A new approach to describe elemental-property parameters", J. Alloys and Compounds, accepted for publication (2006).)

Ternary systems can be displayed in a 2D matrix, too, if one of the elements is pre-selected as "fixed element". The third part can also be a functional group rather than an element, e.g. "[SO4]".

A three-dimensional representation as cube is available for ternary systems or quaternary systems with a fixed element or functional group. For all representations, you can also select the stoichiometric ratio.
