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.

Silicon molybdenum rod
Mainly engaged in Molybdenum tube disilicide heating elements and other molybdenum silicide products development, design and manufacturing, with an annual output of molybdenum disilicide heating elements and other products, 120 tons of molybdenum silicide. Products are sold throughout the country and exported to Japan, Southeast Asia, India, the Middle East, Europe, America and other countries and regions. Currently, the Company's molybdenum disilicide heating elements have occupied 60 percent of the domestic market, by the user's trust and praise.
Molybdenum disilicide heating element is a kind of Molybdenum crucible ilicide based resistance heating element is heated in an oxidizing atmosphere to a high temperature, a dense surface layer of silica glass film to protect it no oxidation. Therefore, it has a unique high-temperature oxidation resistance. In an oxidizing atmosphere, the highest temperature is 1800 degrees, can be used as electronics, ceramics, magnetic materials, glass, metallurgy, refractories and other industrial high temperature furnace heating elements. Molybdenum disilicide heating element resistance does not change with use, which is not aging, so old and new components can be mixed. It should be noted that molybdenum disilicide heating elements not in the range of 400 ~ 700 ℃ long-term use, or the strong component due to low temperature oxidation of pulverized.
