Proprietary-Compound Tungsten electrode is the Tungsten material with two or mote rare earth oxide. Each additive works to the benefit of others and serves as a complement at the same time. Depending on the strong capability in R&D,BTMMF is presided over the Proprietary-Compound electrodes project (which is one of the State 863 Hi-Technology R&D projects). After thousands experiments, we finally found the best-quality composition. When this product is published, it got the approval from the authorities and the experts. Now this product has been exported to European and American, and become the noble in the Tungsten electrodes family. On Jan. 2006, this product is designated to the project that turns from Hi-Tech and become the project supported by the government.
