Molybdenum Cube

In the fields of semiconductor crystal growth, high temperature vacuum furnace and special glass smelting, the reliability of materials directly determines the operating life of expensive equipment. Molybdenum blocks, with their amazing thermophysical properties (melting points up to 2623 ˚ C) and superior mechanical strength, are becoming an indispensable heavy-duty core component in global precision manufacturing.

1. Core feature: "stickler" of physical laws

Molybdenum blocks are not just a pile of metals, it is a "barrier" under extreme working conditions.

Low thermal coefficient: Molybdenum blocks have excellent geometrical stability even above 1500 O C, preventing thermal deformation of the structure.

Excellent thermal and electrical conductivity: superior to most superalloys, it is the choice of electrode materials and heat dissipation substrates.

Chemical inert: Under the protection of high vacuum or reducing gases (such as hydrogen and argon), it has strong corrosion resistance.

2. Production process: "alchemy" from powder to dense entity

The birth of each high-quality molybdenum block needs to go through a rigorous process closed loop:

Isostatic Pressing: Unlike ordinary molding, Isostatic Pressing ensures that the density of molybdenum blocks is absolutely uniform in all directions, which is the key to preventing internal stresses in large-scale components.

Intermediate frequency/vacuum sintering: Under strict control, high temperature sintering is carried out to make molybdenum particles fully cross-linked, and high purity (≥ 99. 95%) dense billets.

Precision forging and annealing: Through forging with large deformation, the grain is broken and the structure is refined, and the subsequent vacuum annealing process completely eliminates the processing stress to ensure that the molybdenum block does not collapse or break in the subsequent machining.

Surface machining: Use numerical control machine tools (CNC) to achieve precise size control and surface finish treatment.

3. Implementation Standards and Purity Ratings: Trust Behind the Data

We are well aware of the pursuit of "consistency" in scientific research and industrial production, and all molybdenum blocks follow: Execution standard: ASTM B386 or GB/T 3867.

Purity guarantee: 99.95% standard. For semiconductor applications, it can provide 4N (99.99%) grade, and strictly control metal impurities such as iron (Fe), nickel (Ni), and copper (Cu) below the PPM grade.

Physical indicators: Density ≥ 10. 22 g/cm3, ensuring that there is no trachoma or cavity inside.
