Tin and Bismuth have low melting points and are relatively easy to process. Tin compounds are used as defoamers in glass production, ferrites in electronic material components, and abrasives for dielectrics and stones. In addition, studies on its use in lithium-ion battery materials and other applications are underway. We believe that Bismuth compounds have a huge potential for growth in the future. They can be used as surge arresters to suppress abnormal voltage, ceramic capacitors that are electronic material components, welding materials, storage batteries for automobiles, and additives for semiconductors and more.
