Molybdenum was discovered in 1778 and it belongs to refractory metals. During the chemical metallurgy of molybdenum, obviously, the produce of molybdenum power is a very important possession. Mosten has excellent facilities and technology to produce molybdenum products. Molybdenum is widely used in electronic-tube, transistors and rectifiers and other electronic devices.
