Abstract: The paper presents and compares three methods for the quantitative description of particle spatial distribution, namely, the linear covariance, Radial Distribution Function (RDF) and tessellation methods. First, model structures were analysed using these methods. It was shown that the particle spatial distribution and the quantitative parameters are clearly interrelated. The presented methods were applied for a quantitative description of the structure of AlN-TiB₂ composite obtained via Self-Propagation High-Temperature Synthesis (SHS). Several parameters quantitatively describing the particle spatial distribution in the studied material were determined. The influence of the structural parameters on mechanical properties was investigated. The results are discussed in terms of further optimisation of the studied material.
