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.

Heilongjiang fork molybdenum exploration total reserves of about 246.6775 ten thousand tons
Shanghai metal mesh recently learned that the Heilongjiang provincial key projects - Songling District fork molybdenum lead-zinc polymetallic ore exploration project obtained a new progress, submit Reserves the amount of 1.76 million tons of molybdenum plating, an average grade of 0.087% molybdenum, molybdenum metal content of 700,000 tons of low-grade, average grade of 0.048% molybdenum, molybdenum totaled approximately 246.6775 million tons; volume of 1 million tons of lead metal and zinc metal content of 140,000 t; silver metal content of 44 tons, became a world-class multi-metal deposit.Smooth implementation of the project, due to "geological survey team prospecting, private capital first, state-owned enterprises to follow up" prospecting advanced mechanism. According to the project feasibility study report, project design for the annual production capacity of 16.5 million tons of ore mining, at current prices, the annual output value of 4.1 billion yuan, tax 970 million yuan, 82.11 million yuan compensation for mineral resources; direct placement around 1,500 people, 3,000 indirect job placement, economic and social development on Daxinanling extremely important strategic significance. Currently, the project feasibility study report has been organized Heilongjiang Provincial Development and Reform Commission reviewed and approved assessment center project and report to the National Development and Reform Commission
