Molybdenum (Mo) Powder possesses a fine particle size and high surface area, rendering it highly versatile in the fields of metallurgy and materials science. It is available in standard particle sizes ranging from -100 to -635 mesh, with even finer sizes down to -635 mesh obtainable in smaller lab-scale quantities. Split-screen fractions like -100+325 mesh are also offered. The oxygen content can be reduced to lower levels through specific reduction conditions.

Molybdenum (Mo) Powder belongs to the molybdenum products range and is selected for high-temperature strength, good thermal conductivity and low vapor pressure. It is commonly used in formulation, sintering, coating, filler, catalyst, electronic material and research use as well as vacuum furnaces, electrodes, heat shields, boats, crucibles and high-temperature hardware. When requesting a quote, confirm purity, particle size distribution, morphology, surface treatment, packaging and quantity.
