Key Features:

Bismuth (Bi):
Bismuth is a heavy metal known for its low toxicity, high density, and unique thermoelectric properties. It is non-toxic compared to other heavy metals like lead, making it an increasingly popular choice in various industries, including electronics, medical applications, and environmental technology. Bismuth’s distinct properties, such as its low melting point and high bismuth content, make it valuable for advanced applications.

Purity (99.9%):
With a purity of 99.9%, this bismuth nanopowder offers a high degree of material consistency. This level of purity ensures minimal contamination and consistent performance, making it suitable for high-precision applications in fields such as nanotechnology, materials science, and electronics.

Particle Size (80nm):
At 80nm, the nanopowder exhibits enhanced surface area and reactivity compared to larger particles. The small particle size improves dispersion, increases chemical reactivity, and enhances interactions with other materials. This makes it a superior choice for applications that require high surface contact and interaction, such as in catalysis and energy storage.

Properties:

Low Toxicity:
One of the most significant advantages of bismuth is its low toxicity compared to other metals, such as lead and mercury. This makes bismuth nanopowder a safer alternative for use in products that come into contact with humans, animals, or the environment, including pharmaceuticals, medical devices, and environmental technologies.
