🔹 Molybdenum Granules 99.95% – High Purity Vacuum Smelted Mo

Molybdenum granules are precision-manufactured metallic particles made from high-purity molybdenum (Mo) that has been vacuum arc melted or electron beam melted to achieve a certified purity level of ≥99.95%. These granules are specifically designed for use in applications requiring extreme thermal resistance, chemical stability, and structural integrity. From advanced vacuum coating technologies and powder metallurgy to high-performance alloying and electronics manufacturing, molybdenum granules play a critical role in modern industry and research environments.

Our molybdenum granules are produced using advanced metallurgical processes, including vacuum arc melting and controlled crushing. This ensures the end product has extremely low oxygen content, a narrow particle size distribution, and consistent elemental composition. With standard granule sizes of 3×3 mm and 6×6 mm and fully customizable options, we offer flexible solutions for demanding technical specifications.

🧪 Chemical Composition & Technical Properties

Each batch of molybdenum granules is produced under strict quality control using high-purity molybdenum feedstock. The granules are subjected to analytical testing via ICP-OES (Inductively Coupled Plasma Optical Emission Spectroscopy) and LECO oxygen/nitrogen analyzers to verify purity and ensure compliance with industry standards.

⚙️ Manufacturing Process

Our molybdenum granules are produced via vacuum arc melting (VAM) or electron beam melting (EBM) techniques, which eliminate volatile impurities and ensure a homogeneous molybdenum matrix. After solidification, the ingots are mechanically crushed and sieved into granule form under cleanroom conditions to avoid contamination.

Key Steps:

High-purity Mo feedstock selection
Vacuum arc melting (inert or high vacuum atmosphere)
Controlled solidification and cooling
Mechanical crushing
Size classification (screening and sorting)
Cleaning, pickling, and packaging

Every batch is traceable with a production code, and customers receive a full certificate of analysis (COA) including chemical composition, particle size distribution, and oxygen content.

📦 Applications of Molybdenum Granules

Thanks to their purity and stability, molybdenum granules are suitable for a wide array of industrial, scientific, and metallurgical uses.

🧪 1. Vacuum Coating and Evaporation

Molybdenum is used in electron-beam and thermal evaporation processes to deposit thin films onto substrates. Its high melting point and low vapor pressure ensure uniform deposition, making Mo granules ideal for:

Semiconductor device fabrication
Hard and optical coatings
Solar panel and display technology

Research shows that molybdenum thin films provide excellent electrical performance and durability, particularly in applications like photovoltaic cells and microelectronics.

🏢 2. Precision Alloying Additives

Mo granules are added to base metals to enhance strength, corrosion resistance, and creep performance in:

Superalloys for aerospace
Titanium-molybdenum biomedical alloys
Stainless steels (such as 316L and 904L grades)

⚛️ 3. Electronic Component Manufacturing

Used in cathodes, anodes, and contact components where electrical conductivity and heat resistance are critical, such as:

Vacuum tube grids
Thermionic emitters
Integrated circuit packaging

🔬 4. Research and Laboratory Use

In laboratories, molybdenum granules are used for material synthesis, metal joining experiments, and evaporation crucibles. Their consistent properties make them ideal for scientific studies and prototype development.
