This is a metallic bismuth (Bi) powder in the micron size range, supplied at 99.9 % purity with a particle size of 200 mesh. It carries CAS number 7440-69-9 and is suited to laboratories and production teams working on alloys, aerospace materials and pyrotechnic compositions.
Bismuth is a heavy, soft metal with a rhombohedral crystal structure. It has a density of 9.8 g/cm³ and a Mohs hardness of 2.5 at 20ºC. It melts at 271.3 °C and boils at 1560 °C, a low melting point that makes it useful in alloy work. Its electric resistivity is 106.8 microhm-cm, and its coefficient of expansion at 20ºC is 13.3 x 10 ⁻⁶.
The powder is offered in 25gr, 100gr, 500gr and 1000gr packs, covering needs from small trials through to larger batch work.
- Used as an alloying addition in the preparation of bismuth-containing alloys.
- Applied in materials development for aerospace components.
- Used as an ingredient in pyrotechnic formulations.
