Molybdenum powder is mainly used in plasma spraying, 3D printing, sputtering target spraying and high temperature resistant coating. The advantages of molybdenum powder are good fluidity, high density, wear resistance and high temperature resistance. Molybdenum powder is generally used in hard surface spraying and high temperature resistant surface treatment. Wococarbide can provide Mo powder products with different particle sizes according to customers' needs.
According to the different particle size content, molybdenum powder can be divided into five specifications: 05 type, 10 type, 20 type, 40 type and 60 type. According to the chemical composition, molybdenum powder can be divided into FMO-1 and FMO -2. FMO -1 is mainly used for large slab and molybdenum silicide electric heating elements; FMO -2 is mainly used as raw material of silicon controlled wafer and molybdenum top.
According to the quality level, it can be divided into two levels:

The two grades are mainly different in the structure of powder, and their physical performance is different from loose density. Grade 1 is high loose density spraying molybdenum powder. It is produced by plasma spheroidization. The powder is solid core spherical structure, and the apparent density is 5.1-5.5g/cm3. The second grade is ordinary spraying molybdenum powder, apparent density: 4-4.5g/cm3. The loose loading density of this kind of powder is low, the ball degree is high, and the production cost is low.
When transporting molybdenum powder, it is necessary to pay attention to moisture-proof and shall not collide violently. Store in dry, ventilated and acid-base free atmosphere to prevent oxidation. The retention period shall not exceed 6 months.
