The aim of the presented research was to analyze ceramic material based on cordierite as a function activation time and sintering temperature. Three-component oxide mixture prepared (MgO + Al2O3 SiO2 in ratio 2:2:5). To decrease temperature, 10 mass % Bi2O3 added this mixture. mixtures were mechanically activated for 5 240 minutes ball mill. Activated sintered at temperatures 1173-1573K. XRD me...

Synchrotrons can be used to generate X-rays in order to probe materials at the atomic level. One approach is to use X-ray diffraction (XRD) to do this. The data from an XRD experiment consists of a sequence of digital image files which for a single scan could consist of hundreds or even thousands of digital images. Existing analysis software processes these images individually sequentially and ...

Hydration and dehydration reaction processes of many organic and inorganic compounds accompany phase changes, and X-ray diffraction (XRD) is a very powerful technique for studying the reaction processes. Thermal analysis is another important technique often used to obtain information needed for understanding the reaction processes. Commercially available instruments for XRD and thermal analysis...

A deep machine-learning technique based on a convolutional neural network (CNN) is introduced. It has been used for the classification of powder X-ray diffraction (XRD) patterns in terms of crystal system, extinction group and space group. About 150 000 powder XRD patterns were collected and used as input for the CNN with no handcrafted engineering involved, and thereby an appropriate CNN archi...
