"Meta-vanadyl ammonium" is a crystalline powder that serves as a raw material for applications utilizing color and many compounds containing V. It is white or slightly yellowish, and when heated, it emits an ammonia odor, loses ammonia and water, and transitions from lemon yellow to reddish-brown, ultimately becoming a dark brown oxide after losing all ammonia. It slightly dissolves in cold water, hot ethanol, and methanol, and easily dissolves in warm water and ammonia water. 【Features】 ■ Raw material for applications utilizing color and many compounds containing V ■ Slightly dissolves in cold water, hot ethanol, and methanol ■ Easily dissolves in warm water and ammonia water ＼ For more details, please check by downloading the catalog ／

Vanadium is a rare metal that is not produced domestically, and most of it is imported from countries such as China, South Africa, and Russia. Our company extracts and recovers vanadium from used catalysts generated at domestic oil refineries, contributing to the stable domestic supply of our products for many years. All vanadium chemical products use recycled materials that are fully recovered in-house. ＼ For more details, please check by downloading the catalog ／

Our company is the only domestic producer of metallic vanadium. We also conduct integrated production from raw materials, supplying high-quality products with low impurity elements. We offer products with low gas components (O, N) and can supply bulk products, powders, and processed items to meet customer needs. In the future, we expect our products to be used in hydrogen purification and nuclear fusion-related applications. ＼ For more details, please check "Download Catalog" ／

Vanadium has properties that improve heat resistance and toughness when added to materials such as steel, titanium, and aluminum, and it is used as a steel additive in high-strength steel, structural alloy steel, tool steel, and more. It is primarily used in high-strength deformed bars and rolled products for constructing skyscrapers, the new National Stadium, and the Tokyo Skytree, as well as in additives for titanium alloys used in aircraft, hydrogen storage alloys, and sputtering targets. In the field of chemical products, it is used as a raw material for denitration catalysts and catalysts for petrochemicals. Additionally, redox flow batteries, which have a low environmental impact, are gaining renewed attention as secondary battery materials. 【Main Uses】 ■ Additive for titanium alloys ＼ For more details, please check "Download Catalog" ／

◆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" ／

We manufacture from recycled materials domestically. There are only a few manufacturers of metallic vanadium globally, and we are the only manufacturer in Japan. We achieve a vanadium purity of over 99.9%. We can process into bulk, powder, or molded products according to customer requests.
