"Priority-2030": Vyatka State University has developed software to study thermal expansion processes.
In 2022, the Department of Technology of Inorganic Substances and Electrochemical Productions at Vyatka State University created a contact dilatometry apparatus designed to measure the thermal expansion of ceramic, glassy, metallic and other solid materials with high precision. Measurements of thermal properties are necessary both for fundamental scientific research and for the certification of industrial samples of materials and products.
“The dilatometer developed at VyatSU has expanded functional capabilities, enabling operation in different atmospheres and at high temperatures. Unlike classical dilatometers, which are limited to a range of 400–600°C, our system allows the study of the expansion of refractory materials, such as glass and ceramics, at temperatures up to 900°C in a strictly controlled atmosphere,” said Alexey Ivanov, a junior researcher at the VyatSU Competence Center “Polymeric Materials.”
As the volume of measurements increased, the university’s researchers automated the data processing. The developed software not only ensures transmission of measurement results to a computer, but also provides the ability to perform self-calibration of the instrument and automatic real-time data processing.
“We can monitor parameters such as temperature and the relative change in the sample’s length. The collected data are uploaded to the software, where the user can set the range of temperatures of interest and enter the sample size for automatic processing. The output is a file that can be exported to any required editor,” said Alexey Vitalyevich.
Thanks to the new software, user interaction with the instrument has been greatly improved, and by minimizing the influence of human factors, measurement accuracy has been substantially increased.
VyatSU scientists regularly release software updates, improving the algorithms for automatic calibration and data processing.
The lack of Russian equivalents with a comparable set of characteristics makes the instrument and software a unique scientific tool in demand in the research community. This is evidenced by the successful deployment of one of the measuring installations at the St. Petersburg branch of the NRC “Kurchatov Institute” – PIYAF-IHS under a commercial agreement.
