Molybdenum carbide has a high melting point and hardness, good thermal stability and mechanical stability, and excellent corrosion resistance and other characteristics. Molybdenum is a silvery white refractory metal, a melting point of 2615 ℃, density of 10.2 g / cm 3, the expansion coefficient is small, a special tube is almost the same coefficient of expansion of the glass. Molybdenum stable at room temperature is higher than 600 ℃, rapidly oxidized.

Tungsten sheet electrode nozzles
One kind of Kekai tungsten electrode nozzles, spray drying areas belonging to the field of mechanical equipment . The utility model using tungsten carbide materials and improve the structure of the nozzle so as to adapt to the high-pressure spray tungsten carbide nozzles. The utility model includes a protective shell , nuts, tungsten carbide rods nozzles core inserted in a protective case , and then tighten the nut on the protective shell. In addition to the utility model is characterized by the use of tungsten carbide rod nozzles as the core material , greatly improved wear resistance , but with the traditional nozzle structure also improved .
