wallpapers Resource 2020-11-18
Molybdenum powder is usually prepared from ammonium paramolybdate or calcined MoO3 as a raw material and reduced with hydrogen. It is a raw material for preparing molybdenum deep-processed products by powder metallurgy.
Molybdenum powder is an important inorganic mineral. From a geological point of view, molybdenum powder is a natural mineral of the earth's crust.
Classification of molybdenum powder
Molybdenum powder is divided into sprayed molybdenum powder, ultra-fine molybdenum powder, nano-molybdenum powder, large-size molybdenum powder, and high-purity molybdenum powder

Test method for molybdenum powder
1. The chemical composition analysis of the product is carried out according to the regulations of GB/T 4325 (all parts).
2. The Fisher particle size determination of the product shall be carried out in accordance with the provisions of GB/T 3249.
3. The particle size distribution of the product is determined according to the method negotiated between the supplier and the buyer.
4. The loose density of the product shall be determined in accordance with the provisions of GB/T 1479.2.
5. Visual inspection of product appearance quality.
Export volume of molybdenum powder
From January to May 2020, China's molybdenum powder exports totaled 169.71 tons, an increase of 20.75% over the same period last year. Among them, China exported 34.617 tons of molybdenum powder in May, an increase of 110% month-on-month and 43.6% year-on-year.
Data show that in May, China exported 19.1 tons of molybdenum powder to Japan, an increase of about 3.8 times from the previous month; exports to South Korea were 4.005 tons, a decrease of 33.25% from the previous month; exports to the United States were 0.402 tons, an increase of 101% from the previous month.
