Application

The purpose of the Bismuth single crystal, with dimensions of 15mm diameter and 25mm length, and a (100) orientation, lies in its exceptional properties that make it suitable for various advanced applications. As a brittle, yet heavy and lustrous metal, bismuth's unique diamagnetic characteristics and low thermal conductivity distinguish it from other metals, making it especially valuable in specific industrial and scientific contexts. This particular orientation and form are ideal for exploring bismuth's potential in the development of semiconductors, thermoelectric materials, and nuclear research, where its high density provides effective gamma-ray shielding, and its low neutron absorption allows for efficient neutron passage. Additionally, bismuth's properties enable its use in low melting-point alloys for safety devices and in cosmetic or medicinal compounds. This crystal exemplifies bismuth's versatility and utility in advanced technological and scientific fields.
