Quantitative analysis: state of the art and new perspectives Dear all, you are cordially invited to present your contribution at the microsymposium "*Quantitative analysis: state of the art and new perspectives*". Congress: European Powder Diffraction Conference 18 Venue: Padova (Italy) – August 30 – September 2, 2024 Session: MS12 - Quantitative analysis: state of the art and new perspectives *Description: *The quantitative phase analysis (QPA) of complex samples has long been a scientific endeavour of great importance and QPA is now a powerful tool for researchers seeking a detailed understanding of materials and their applications to natural and industrial processes. Taking advantage of the existing experimental set-ups and software, QPA allows the determination of the composition of mixed crystalline and amorphous complex matrices such as ceramics/glass-ceramics, cementitious materials, bricks, alloys, pharmaceutics, catalytic materials, raw materials, soils, wastes and secondary raw materials, and many more. Furthermore, QPA is essential in studying structural changes during phase transformations, providing valuable insights into the behaviour of materials under non-environmental conditions. Extracting accurate and reliable data from the powder patterns is still far from being a routine method, and it requires innovative approaches and meticulous corrections, calling for detailed analytical protocols. This symposium focuses on the state-of-the-art of QPA and welcomes contributions on the use and recent advances of this analytical method in both academic research and industrial applications.*Keynote 1: **Giuseppe Cruciani (Univ. of Ferrara, Italy) *Quantitative phase analysis as a tool to develop the circularity of construction and demolition waste.*Keynote 2:** Ruben Snellings (Katholieke Univ.
