◆Vanadium Sample Containers for Neutron Scattering Experiments Soleil Mining Co. handles vanadium containers for neutron scattering experiments. Vanadium (V) has the characteristic of having a small negative value for the interference scattering wavelength, but it is not zero. Therefore, a Bragg peak originating from vanadium is detected. Soleil Mining Co. has successfully developed sample containers that minimize this peak to nearly zero by adding elements to the vanadium. These were developed in collaboration with the High Energy Accelerator Research Organization. Soleil Mining Co. can provide you with superior sample containers for neutron scattering experiments. This eliminates the occurrence of peaks from sources other than the measured sample, enabling measurements with very high precision.

Vanadium dioxide (VO2), which exhibits a metal-insulator transition, is known to be useful as a phase change material (PCM) because it generates a large latent heat without melting. However, there was a challenge due to its low thermal conductivity, which prevented the interior from undergoing a phase change instantaneously. Therefore, we developed a solid latent heat storage material with high thermal responsiveness by appropriately dispersing metal and using spark plasma sintering (SPS). 【Features】 ■ Can store heat without melting, unlike typical PCMs ■ Maintains processability equivalent to metals ■ High thermal responsiveness *The developed product is about 470 times that of paraffin (as of 2023) ＼ For more details, please check "Download Catalog" ／

At Taiyo Mining, we recognize "the protection of the global environment" as an important issue and have aimed to establish products and technologies that are friendly to both people and the Earth. One of the results of this effort is the recycling system for valuable resources such as molybdenum and vanadium. We have increased the recycling rate of rare metals and achieved stable supply, receiving high praise even overseas. In oil refineries, molybdenum-based catalysts are used as desulfurization catalysts to improve oil quality and remove sulfur, which causes air pollution. Catalysts that have lost their activity are separated and recovered through our resource recycling process, which retrieves molybdenum and vanadium that adhered during refining. Additionally, the remaining alumina ore is effectively utilized. Moreover, in oil refineries, catalysts are also active in processes such as metal removal, nitrogen removal, and decomposition, in addition to desulfurization. 【Features】 ■ Increased recycling rate of rare metals and achieved stable supply ■ Separation and recovery of molybdenum and vanadium adhered during refining ■ Effective utilization of remaining alumina ore ■ Catalysts are active in oil refineries for metal removal, nitrogen removal, decomposition, etc. ＼ For more details, please check "Download Catalog" ／
