Features of Factory Molybdenum Aluminum Boride Powder MoAlB Powder 99%Min 200-500mesh
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Molybdenum Aluminum Boride (MoAlB) Powder, also known as MoAlB powder with a minimum purity of 99%, is a high-performance ceramic material that finds extensive applications in various industries due to its unique combination of properties. This particular grade of powder has a particle size range of 200-500 mesh, ensuring a consistent and uniform distribution, which is crucial for optimal performance in composite materials, coatings, and advanced technological applications.
The synthesis of MoAlB powder begins with the careful selection of raw materials, including high-purity molybdenum, aluminum, and boron. These elements are combined through a controlled chemical reaction at elevated temperatures, resulting in a compound with a hexagonal crystal structure. The powder’s formation involves a milling process, during which the larger particles are reduced to the desired 200-500 mesh size, ensuring a homogeneous mixture without any agglomerates.
One of the key features of MoAlB powder is its exceptional thermal stability, making it resistant to high temperatures up to 2000°C. This property makes it ideal for applications in aerospace, where components must withstand extreme conditions, as well as in the automotive industry for high-temperature components like exhaust systems. Its low thermal expansion coefficient also minimizes dimensional changes under heat, contributing to improved mechanical integrity.
MoAlB powder exhibits excellent wear resistance and hardness, which is beneficial in applications requiring friction reduction or protection against abrasive environments. It is often used in brake pads, cutting tools, and wear-resistant coatings. Additionally, its electrical conductivity, although lower than metals, is still appreciable, making it suitable for certain electronic and electromagnetic shielding applications.
In the field of electronics, MoAlB can be used as a sputtering target to deposit thin films with desirable properties, such as high thermal conductivity and resistance to corrosion. Its use in this context extends to microelectronics, solar cells, and semiconductor manufacturing.
Furthermore, MoAlB powder is known for its good chemical inertness, non-spalling characteristics, and low coefficient of friction. These traits make it suitable for applications in the bearing industry, where it can improve the performance and longevity of components subjected to heavy loads and sliding contact.
Another area where MoAlB powder thrives is in the development of advanced composite materials. Its high strength-to-weight ratio and excellent bonding properties enable it to reinforce polymer matrices, ceramics, or metals, leading to lightweight yet robust structures in the aerospace, automotive, and construction sectors.
In summary, Molybdenum Aluminum Boride (MoAlB) powder with a 99% minimum purity and 200-500 mesh particle size is a versatile material with a multitude of applications due to its exceptional thermal stability, wear resistance, and inherent properties. Its widespread use ranges from high-temperature engineering components to advanced functional coatings and composite reinforcements, making it a critical material in modern technology.
